Green mine construction creates a mystery of 90% profit

Eco-friendly enterprises are prosperous. The annual profit of 90 percent from the green mine construction, Dulan gold mining company fai prove with their own practical action to the community: the development of green mining, building green mines not only suffer, but also the big payoff.

Mining enterprises are the mainstay of green mine construction, which is related to the success or failure of green mine construction, and directly related to the green development process of China's mining industry. In recent years, under the great attention of the Party Central Committee, under the advocacy of the Ministry of Land and Resources and other ministries and commissions, local governments have actively sought the balance between mining development and ecological protection, and green mine construction has entered the fast lane.

However, in some places, there are still a few mining enterprises that have a partial understanding of “the construction of green mines must be invested heavily in increasing costs”. Some mining companies believe that there is no need to build green mines for short mining periods, and some mining companies feel that they are surrounded by mining areas. Good ecological environment does not require the construction of green mines. All of these are manifestations of the lack of understanding of the green development concept, which makes these mining enterprises less active in the construction of green mines, directly affecting the overall progress of the national green mine construction.

Green is the greatest productivity. The construction of green mines is not only the need of ecological civilization construction, but also an effective means for mining enterprises to cultivate new development kinetic energy, improve core competitiveness and achieve sustainable development of enterprises. Green development is the “bottom line” for mining companies and an iron rule that mining companies must follow. At the symposium on green mine construction held by the Ministry of Land and Resources recently, Ling Yueming, deputy director of the Ministry of Land and Resources, pointed out that it is necessary to use incentives and constraints to mobilize the enthusiasm of mining enterprises, enhance endogenous power, and truly make the rules of mining enterprises "Taste the sweetness", let the mining enterprises that are chaotic as "eat a bit of pain."

We firmly believe that with the continuous emergence of law-abiding mining enterprises and the increasing number of green mining enterprises, mining enterprises such as Jinhui Mining, which have tasted the sweetness from the construction of green mines, will benefit greatly!

Guanghui is the Jinshan Silver Hill. Recently, when the China Mining News reporter walked into Jinhui Mining Co., Ltd., located in the Gobi Desert of the East Kunlun Mountains, and witnessed the tremendous changes brought about by the company's construction of green mines, it was known that the scientific theory of "two mountains theory" was The far-reaching significance and impact of practice.

“Green is the biggest productivity. Our company's current annual profit of more than 90% comes from the construction of green mines.” Zhang Qiyuan, the chairman of the company who tasted the sweetness from the construction of green mines, excitedly told the China Mining News reporter, “If we don’t build The green mine is still in accordance with the level of mining five years ago, then we are now at a loss."

Green development is the only way for the mining industry and an inevitable requirement for the construction of ecological civilization. At present, there are still some mining enterprises that have a one-sided understanding that “the construction of green mines will inevitably increase the cost”. Why does Jinhui Mining Company stand out from the crowd and prove its charm of green development with its own practical actions? More than 90% of its green profits are How to get it? With all kinds of questions, the China Mining News reporter once again went deep into Kunlun Mountain and revealed the Jinhui Mining Company.

Green idea in my heart

Jinhui Mining Co., Ltd., located in Wulonggou District, Dulan County, Qinghai Province, was established in September 2006. It is a collection of 13 exploration and mining projects selected by the Qinghai Provincial Bureau of Geology and Mineral Resources and 13 Geological Prospecting Units. The large-scale gold mining enterprise integrating the comprehensive utilization of tailings is also one of the “three pillar industries” of Qinghai Provincial Bureau of Geology and Mineral Resources.

Walking through the mining area, in addition to enjoying the joy of green trees and birds and flowers in the Gobi Desert, you can also deeply feel the company's new "green culture" - "firm ecological self-confidence and enhance ecological consciousness. Various signs of green development, such as realizing self-improvement, respecting nature, adapting to nature, protecting nature, beautifying nature, respecting nature, and gratifying nature, can be seen everywhere.

“The key to building a green mine is innovation in concept. We have a series of important speeches from General Secretary Xi Jinping’s “four solid and solid” and “developing and utilizing under the premise of protecting the ecological environment” In the mining industry, the company’s chairman Zhang Qiyuan said with deep feelings, “Only by the green development concept, the development path of harmony between man and nature can be developed in the mining industry. We will continue to create a green development atmosphere by actively advocating and implementing the national guidelines and policies, and we are now deeply rooted in the company's cadres and workers, and we are beginning to transform into a personal development. Conscious action."

Ideas determine practices, ideas guide actions. In recent years, the company has complied with the requirements of the times, fully implemented the “four transformations” of the Qinghai Provincial Party Committee and the call for the construction of the “Eco-civilization Pioneer Zone” and the “Green Exploration and Development Year” of the Qinghai Provincial Department of Land and Resources and the Qinghai Provincial Bureau of Geology and Mineral Resources. To deploy and conscientiously implement the overall requirements of the “four fronts in the province” and the construction of “Damei Qinghai, the most beautiful Haixi” and the county government of Dulan County to build “Ecological Dulan and Splendid Dulan”. Vigorously promote the construction of green mines, and use 100% of the energy to carry out the work of “greening, greening and re-greening” in the mining area, and successfully explored the “green development model” suitable for the characteristics of Qinghai Plateau, and was included in the Qaidam Circular Economy Experimental Zone. Key enterprises and key enterprises in the gold industry park of Qinghai Province.

Through the construction over the past few years, the company has built recreational facilities such as landscape pavilions, artificial lakes and music fountains, fitness plazas, and national fitness centers. It has successfully planted various green plants and explored the mixed cultivation of trees, shrubs and grasses. The greening road has effectively improved the natural environment and climatic conditions of the mining area, and gradually formed a new scene of green trees, birds and flowers, and harmony between man and nature, making the mining area become the hinterland of Kunlun Mountain and the desert Gobi of Qinghai Plateau. An oasis on the beach.

Recently, after the main leaders of the Haixi State Committee visited the company, they fully affirmed the construction of green mines with the words “very beautiful and particularly shocking” and asked all resource-based enterprises in the state to come and observe.

"Point stone into gold" benefits come

The company's green mine construction with ecological protection priority as its core, such as the four-and-two-pronged, brings a steady stream of “real gold and silver”.

"We have adopted a series of green development measures such as improving resource utilization, energy conservation and emission reduction, recycling, and technological innovation to control the production cost to the advanced level of similar gold mines in China, and the profits generated by this account for the total profit of the enterprise. More than 90% of the company not only did not increase the cost of the enterprise, but also greatly promoted the development of productivity and significantly improved the economic benefits of the enterprise." Zhang Qiyuan said.

Since its establishment, the company has always adhered to the four principles of “rich and poor, difficult, thin, and large”. In the mining process, advanced digital software for mines was used to establish a digital model of the mine, realizing the space of each ore block. Location, grade, ore, metal amount and other information can be extracted and inquired at any time to visually display the area and location of different grades. By using the geological model and the measured solid model of the measured roadway, the three-dimensional modeling of the stope design and the medium-deep hole blasting design is realized. The blasting parameters in the blasting range can be directly calculated. According to the medium-deep hole design, the grading model can be designed. Calculate the amount of ore and grades before and after depletion of each blasting mine, effectively guide the mine mining and ore blending work, and control the depletion of ore.

“According to the expert group's argument, the mine mining grade is 2.39 g/t, the current grade is 2.49 g/t, and the grade is 0.1 g/ton. This alone increases the annual economic benefit by about 15.5% of the total profit.” Zhang Qiyuan said.

The ore type of the Wulonggou area where the company is located is a fine-grained altered rock type easily muddy gold ore. The size of the gold inlay is fine and fine. Therefore, the ore needs fine grinding, but since the ore contains about 37% of argillaceous minerals, It is easy to produce a large amount of secondary slime and affect the flotation index. They determine the amount of sand returned by grinder crushing products and cyclone bottom flow and the amount of sand return in the bottom of the grinding grader cyclone, combined with the theory of steel ball grading and the grinding effect in production practice to determine the mill. Steel ball grading scheme, real-time grinding and grading process inspection, revision and improvement of steel ball supplementation system, improve grinding efficiency, solve the problem of “over-grinding” and “under-grinding” of grinding operations, and ensure that grinding products meet the requirements of grinding products. Flotation process requirements reduce mill energy consumption and steel ball consumption.

“We carried out a large number of mineral processing techniques to analyze the problems in the beneficiation process and the changes in ore properties, conduct flotation test research in a timely manner, continuously optimize the pharmaceutical system and process conditions, summarize the best process parameters, and stabilize the beneficiation process, thereby improving Flotation recovery rate, flotation recovery rate increased from 77.0% to 81.9%, which can increase economic benefits by about 20.2% of total profit each year." Zhang Qiyuan said with a sense of accomplishment.

The company's "building dam in the dam" mode is to make full use of the well-prepared and well-stabilized sand and gravel materials to form dams, which not only shortens the transportation distance and raw material cost of dam materials, but also The construction of the dam and mulch filming site in the later stage was leveled, which saved a lot of construction cost of the tailings pond. According to rough statistics, the company has reduced the cost of new tailings storage by more than 17 million yuan through the construction of this innovative tailings pond, and the annual damming cost has been reduced by more than 20 million yuan, equivalent to an annual savings of 25.8% of the total profit. %.

Even in other companies, it is very insignificant, and it is the easiest to “run and leak” and pollute the environment. In this company, it has also become a profitable tool for “Daijinjinjin”. They reconstructed the backwater pumping station that was originally located at the bottom of the tailings pond, and made a mobile backwater pumping station by welding. The position of the pumping station increased with the height of the tailings dam surface, which not only reduced the height difference of the return water, but also The laying and conveying distance of the return water pipeline is shortened, the operating efficiency of the water pump is improved, and the power consumption is reduced. By improving the tailings pond return system, annual electricity and maintenance costs are reduced by approximately 2.4% of total profit.

Through the collapse mechanism, they built a tailings discharge management mode of “multi-point small flow, dry beach dam” to improve the quality of the return water, install an automatic control pump at the original backwater pumping station of the tailings pond, and timely recover the wastewater. The recycling of ore dressing wastewater has truly achieved zero pollution and zero emissions from flotation wastewater. At the same time, they rectified the underground well water, discharged all the water in the well through the construction drain hole to the transport flat, and discharged it to the mouthwash backwater device through the transport ditch. The transfer pipeline is installed in the Pingshuo backwater device, and the downhole water is transported to the tailings pond. After being settled by the tailings pond, it is recycled for use in the plant selection, realizing the recycling of underground water and “zero discharge”.

“The above two measures save more than 3.1 million yuan per year, accounting for 3.7% of the total profit. At the same time, these measures not only eliminate waste water discharge and environmental pollution, but also reduce the amount of fresh water produced by the plant, and increase the green area of ​​the mine. The conditions were created to increase the irrigation and greening area of ​​the mining area by nearly 300 mu without increasing the water supply and pipelines, contributing to the construction of the 'garden-type mine' and the greening of the mining area,” Zhang Qiyuan said.

Innovation is the driving force for enterprise development, and innovation in the company has also become a source of benefits. In recent years, the company has earnestly carried out the “all-in-one innovation” campaign, encouraging all employees to participate in independent innovation and rewarding innovative projects, which has fully stimulated the company's overall innovation enthusiasm and promoted the company's ability to innovate. In recent years, the company has received 189 innovative projects. Through innovation, technical improvements such as equipment improvement, optimization process, and simplified procedures have been carried out in various production links such as mining, flotation, and tailings management, which have improved equipment operation rate and work efficiency, and reduced material and energy consumption. Innovative projects in all aspects save annual production costs or increase economic benefits by more than 10 million yuan, accounting for 11.9% of total profits.

"We are through the transformation of coal-fired boilers, took electric heating heating energy efficient centralized control, effective control of the heating area and winter ranges, to achieve different temperatures in different regions, reducing energy waste and reduces management heating system The maintenance cost can save more than 2 million yuan per year, accounting for 2.4% of the total profit. The project not only saves costs, but also reduces exhaust emissions and reduces environmental pollution.” Zhang Qiyuan took the finger to the China Mining News reporter to calculate the benefit account. Come, "the company actively fulfills its corporate social responsibility, actively cooperates with the local new rural construction, actively participates in local rescue and disaster relief, and implements 'poverty alleviation and hardship' in a solid manner. According to the idea of ​​'happy and proactive poverty alleviation, steady and rapid poverty alleviation', it is really helpful for local farmers and herdsmen. Supported, created a good relationship between the enterprise and the production and living environment. At the same time, strengthen the environmental protection of the mining area, communicate with the local farmers and herdsmen, and live in harmony, without any incidents such as petitions, reports, environmental pollution, etc. More than 1 million yuan, accounting for 1.2% of total profits."

"Then you have to invest in the landscaping and greening of the mining area?" Faced with the doubts of the China Mining News reporter, Zhang Qiyuan is proud to point to Guanjingting: "All greening in the mining area, including artificial lakes and viewing pavilions And all the flowers and trees, we are co-constructed with the construction enterprises and the company's cadres and workers work overtime to work out. Especially the construction of the observation pavilion, the company employees sacrifice the rest time, first dump the soil bag on the mountain bag, then plant The flowers and grasses have been built, so the greening of the mining area includes the management of the tailings pond and the waste rock pile, and there is almost no investment."

Green is always on the road

Green development is endless and expensive. In recent years, the company has actively implemented the concept of green development. “Never sacrifice economics and waste resources at the expense of temporary economic growth.” While acquiring wealth from nature, it is in line with nature, protecting nature and beautifying it. Naturally, awe of nature, grateful to nature, and consciously carry out the coordinated development of economic growth and ecological environment throughout the development of mining. In 2016, the company was identified as “National Green Mining Development Demonstration Zone” by the Ministry of Land and Resources, and it was one of the 50 “National Green Mining Development Demonstration Zones” built during the “13th Five-Year Plan” period.

In the green development, they are unique, starting from every detail of every link, not only "face", but also "lizi", and strive to build an essential green mine. They conscientiously implement the environmental protection requirements for the restoration and control of the geological environment of the mine. The flotation adopts a clean-up process to explore ducks and geese in the clarification area of ​​the tailings pond. In order to avoid the pollution of the tailings pond dust to the environment, the company planted green plants such as barley on the pulp in the dryland area of ​​the tailings pond. At present, the tailings ponds, ducks and geese are in groups, and the green scorpions are in pieces, which have been highly recognized by the local safety supervision and environmental protection departments. In order to protect the Wulonggou natural wild oak forest, they invested in the construction of the rail transit system, which not only reduced the pollution of the original ecological forest and the surrounding environment during the transportation of the automobile, but also shortened the transportation distance and saved the transportation cost. At the same time, they made full use of the waste residue generated by the construction of the tunnel, built the mining industry site, turned waste into treasure, and built the first-class rail transportation industrial site and the mining and transportation dispatching center in the province.

"We have a new concept now, that is, to transplant the hospital's 'minimally invasive' surgical concept into the construction of the mine. In the mining development, try to reduce the 'surgery' as much as possible, if you really want to use the 'minimally invasive' 'Small surgery' to minimize the disturbance to the ecological environment, and to suture after surgery, to achieve perfection, even beyond the original effect." Zhang Qiyuan said.

It is understood that at present, the company is guided by the development concept of “innovation, coordination, green, openness and sharing”, and has determined that “green mines are the forerunner, safe mines are the guarantee, rule of law mines as the bottom line, innovative mines as the driving force, and digital The construction of the “Ten-type mine” with the means of mine as a means, science and technology mine as the way to lead, open mine as a way, benefit mine as the support, humane mine as the foundation, and harmonious mine as the goal, has drawn a clear development idea for the development of Jinhui Mining. .

The green hills are the Jinshan Yinshan, and the construction of green mines is always on the road. "We will take the 'Qinghai Gold Mine Resources Development Engineering Technology Research Center' as an innovation platform, thoroughly implement the 'Five Developments' concept, effectively and effectively promote the construction of 'Ten-type mines', change concepts, take the initiative, in the green development concept Stride forward and strive to turn Dulan Jinhui Mining Co., Ltd. into a domestic first-class modern green gold mining enterprise during the 13th Five-Year Plan period," Zhang Qiyuan said.
