Green Mine Zhaojin Group: Strengthening Environmental Protection and Building Green Mines

Zhaojin Group always adhere to environmental guidelines "abide by environmental regulations, prevent environmental pollution and promote energy reduction of waste, rational use of resources, focus on continuous improvement, create green mining" in order to achieve safety, production, environmental protection and the simultaneous development of speed, efficiency synchronous growth As a goal, we will place environmental protection work in a prominent position, strengthen comprehensive management, and build an ecological enterprise. Zhaojin Group has been awarded Shandong Province circular economy the top ten scientific management model enterprise in Shandong environment-friendly enterprises, environmental protection and other outstanding enterprises honorary title of environmental work experience in the country to promote non-coal mining enterprises. At present, 11 mining companies of Zhaojin Group have reached national-level green mining enterprises, and five enterprises have already reported to the state and are now in the process of examination and approval. All mines have reached clean production enterprises, achieving a double harvest of enterprise benefits and ecological benefits.

Further raise awareness, strengthen responsibilities, and put environmental protection work on the agenda. "To protect the environment, we must not leave pollution to the society and leave it to future generations." This is the consensus reached by Zhaojin Group from top to bottom in mine development. Zhaojin always adhere to the "first to Guanghui, then to Jinshan Silver Hill," the concept of environmental protection, to further strengthen the leadership of environmental protection, the implementation of number one person take overall responsibility of the work system. The environmental protection targets of “contaminant discharge standards, elimination of major environmental pollution accidents, reclamation greening rate of not less than 80%, and usable waste recovery rate of over 90%” are listed as environmental protection targets, and environmental protection work is regarded as a benefit for future generations. The descendants of the German government work to grasp, and strive to achieve a harmonious development of the economy and the environment. At the beginning of each year, Zhaojin Group has signed “Environmental Responsibility” with each enterprise, and incorporates the objectives into the assessment of production economic responsibility system at all levels, and implements a monthly inspection and monthly assessment system to form a first-level level. The environmental protection work pattern of the first-level insurance level lays the foundation for the environmental protection work idea to be in place, the responsibility is in place, the system is in place, the application is in place, and the assessment is in place. At the same time, Zhaojin Group also actively implements the "Environmental Protection Law", "Mineral Resources Law", "Energy Conservation Law", "Circular Economy Law" and other laws and regulations, strengthen employee training and study, and insist on holding an environmental protection work meeting every month to analyze the situation. Solve problems, correct deficiencies, and ensure the effective implementation of environmental responsibility systems at all levels.

Further increase investment in science and technology, vigorously implement scientific and technological innovation, and improve resource utilization efficiency. Environmental protection is inseparable from the investment in technology. In order to promote the environmental protection work of enterprises to a new level, Zhaojin Group has continuously increased investment in environmental protection through the use of post-doctoral research stations, academician workstations, enterprise technology centers and other technological innovation platforms, and invested in environmental protection and “three wastes” governance every year. More than 100 million yuan, focusing on the development of key technologies and equipment for efficient energy conservation, ecological restoration, and resource recycling. In terms of mining, in view of the characteristics that the mine mining depth is declining year by year and gradually transferred to deep mining, research on deep ore body mining methods is carried out, focusing on solving complex mining technology conditions, low mining efficiency in harsh environments, high loss and high rate of loss, and safety. Problems such as difficulty in production guarantee, through the study of ground pressure management and the law of ore flow, using the theory of ground pressure control, research and development of complex ore mining technology under deep well conditions; continuously improving the level of equipment for mining, and using information technology to build green Ecological mines are close to the international advanced level. In the aspect of mine selection and smelting, the first is to strengthen the recovery research of refractory smelting; the second is to strengthen multi-element comprehensive recovery, eat dry and squeeze; the third is to carry out new smelting method test and carry out research on cyanide-free gold.

Further strengthen supervision and strengthen the management of tailings ponds, subsidence areas, goaf areas and “three wastes”. The tailings pond, the subsidence area and the goaf have always been the focus of Zhaojin Group's environmental protection work. During the “Twelfth Five-Year Plan” period, on the basis of centralized management, Zhaojin Group made great efforts to grasp the comprehensive management of tailings ponds, subsidence areas and goafs, and adopted effective measures such as soil compaction, backfilling, and afforestation. Restore ecological balance and improve environmental quality. In recent years, 96 million yuan has been invested in the tailings pond, subsidence area, and goaf treatment. The tailings pond is maintained, afforested, vegetation, slope protection, dam surface compaction, water sprinkling and dust suppression. Zhaojin Group has more than 60,000 square meters of green vegetation per year, planting more than 30,000 trees, reclaiming more than 80,000 cubic meters of land, building 22 new sewage treatment plants, increasing 26 sets of boiler dust removal and desulfurization facilities, and upgrading and upgrading the plant to remove dust. 38 facilities, beautify the mine environment, purify the mine air, and achieve the environmental goals of “blue sky, clear water and green land”. In terms of “three wastes” governance, Zhaojin Group strictly enforces the “three wastes” emission system, continuously increases investment in environmental protection facilities, and invests more than 300 million yuan in the “three wastes” governance, focusing on strengthening cyanide, chemical wastewater, smelting soot, and boilers. The emission index of soot is controlled, so that the waste water is not discharged, the exhaust gas reaches the standard discharge, and the waste slag is standardized, so as to prevent the occurrence of pollution accidents. In the aspect of wastewater treatment, the tailings are all returned to the production process for recycling after sedimentation and filtration; the cyanide wastewater is treated by the sewage treatment system, and all of them are returned to the process to achieve zero discharge of cyanide-containing wastewater. In the aspect of waste gas treatment, the smelting soot treatment project is implemented. After the flue gas is treated, the emission concentration of nitrogen oxides should be below 200ppm. In the aspect of waste slag treatment, the gold concentrate and the sulphur mine are ground hardened, and a shelter is built and covered with tarpaulin to prevent rainwater loss and dust.

Paying attention to science and technology, tackling difficulties and tackling key problems, and achieving major breakthroughs in dust control work. In recent years, Zhaojin Group has actively used scientific and technological means to achieve major breakthroughs in dust control. Cooperation with the United States, Andy Fenlan Bo Environmental Protection Technology Co., Ltd., invested 1.8 million yuan using bio-nano dust suppression systems at the Jinchiling gold processing plant Sec crusher, after several site visits and repeated authentication, determine that the project can The application was promoted and a bio-nano-dust suppression system was installed at the broken place in the Da Yin Ge Zhuang gold mine. The use of the system enables the dust of the dust point to be effectively controlled. The total inhibition rate of the dust is up to 95%. The dust is not flying at 5 meters from the equipment, and the operator can wear it without 95% of the time. Dust mask. On December 2, 2013, Zhaojin Group organized a site meeting for the promotion and application of bio-nano-dust suppression technology in the Jinyiling Gold Mine, and decided to promote and apply it throughout the company in 2014 to completely solve the dust suppression problem at the job site.

The environmental protection issue determines the development environment of Zhaojin, which affects the brand building and sustainable development of Zhaojin. Zhaojin Group will further strengthen leadership, strengthen measures, develop and innovate, establish an ecological civilization concept of “respecting nature, adapting to nature, and protecting nature”, placing ecological civilization construction in a prominent position, and making full efforts to protect the environment and mine ecological environment. Realize the simultaneous development of economic and ecological benefits, benefit the enterprise, benefit the society, benefit the people, and make due contributions to building a beautiful golden capital and beautifying the gold!
