Welcome to the official website of Hainan Mining.
We systematic planning and promotion "green transformation" sustainable development rout, continuously optimizes the energy structure, improves the comprehensive utilization rate of energy, designs the green low-carbon long-term mechanism, improves the comprehensive ability of energy saving and emission reduction,establishes a clear division of labor, clear authority and responsibility, synergistic and efficient management mechanism, and all staff participate in promoting the "green transformation" development and construction.
We strictly abide by the Environmental Protection Law and the Air Pollution Prevention and Control Law etc., and constantly improve the environmental management system by revising the "Measures for the Protection of Environmental Management"; Optimize the environmental management organization structure, set up a Safety and Environmental Protection Department in the headquarter.
We have established a comprehensive environmental management mechanism, especially in the difficult aspects of environmental management, such as identification of environmental risks, monitoring of pollution factors, hidden trouble detection and management and noise control, groundwater pollution prevention and control, etc., formulated the "Compliance Evaluation Management Measures", "Emergency Response Plan for Environmental Emergencies", "Pollution Sources Self-Monitoring Measures" and other systems and documents, and our subsidiary companies have also established systems such as "Environmental Risk Hidden Danger Detection", "Soil and Groundwater Management Measures "， which standardize the implementation requirements and clarify the division of responsibilities and penalties in terms of management responsibilities, workflow, performance indicators, assessment and evaluation.
In terms of environmental emergency management, we revised the "Emergency Response Plan for Environmental Emergencies" in 2022, adhering to the principles of "Safety First, Precaution Crucial, Comprehensive Management, Public Participation, and Responsibility for Damage", and carried out whole-process and hierarchical control on risk management, prevention and early warning mechanism, information reporting, emergency response and emergency security, etc., to ensure that environmental emergencies are dealt with in a scientific and efficient manner.
We focuses on the sustainable development of mining ecosystems, and has explored a model of "development, protection and greening" through mine reclamation, reforestation, ecological restoration, etc., and continuously improves the rate of vegetation coverage and greening rate of the plant, which improves the carbon sequestration capacity of mining ecosystems, and achieves the purpose of controlling and reducing carbon emissions.
Since the establishment in 2007 to 2022, we have finished a total of 3,322,500 compulsory tree planting, ecological restoration of an area of 3,461,900 m², and a total of 160 million yuan in treatment funds. In the past four years, a total of 838,400 trees have been planted in areas such as the quarry under the maple tree, the backfilling area, and 324,200 m² have been used in the ecological restoration of the reclaimed land, and 41,500 m² have been used in the repair of the slopes and terraces by spraying.
We has set up the energy management policy of "full participation, energy conservation priority, scientific and technological innovation, and low-carbon development", continuously improved the construction of the energy management system, and established the energy management organization structure.Especially for Shiliu Iron Ore Branch, which has set up a special energy saving leading group and a deputy general manager in charge of energy saving management.
We promotes the energy management system certification work, and in 2022 has obtained ISO 5001:2018 energy standard certification. The energy used in the company's production and operation process is mainly electricity, diesel oil and a small amount of gasoline. In order to save energy and improve the energy utilization rate, we adopts a series of ways to improve the energy use efficiency.
The sources of water consumption of Hainan Mining mainly include new water and production cycle water. We vigorously develops production recycled water utilization projects, optimizes the construction of industrial water pipeline network, and increases the proportion of recycled water in the total water consumption. In 2022, our industrial water recycling utilization rate was 95.55%, an increase of 1.21% year-on-year, and reduced new water consumption by 642,700 cubic meters year-on-year, a decrease of 21%.
In order to protect water resources and improve the utilization of water resources, We has vigorously developed recycling water utilization projects in the process, formed an effective circulating water management mechanism, and achieved good water-saving benefits.
The ore dressing wastewater is treated through the tailings concentration pond in the plant and all the overflow water is reused. After the tailing enters the tailing pond and precipitates, the tailing is stored in the pond, and the overflow water enters the tailing pond (3000m³) through the overflow well, flood discharge tunnel, and dissipation pond, and is finally pumped back to the beneficiation plant. Beneficiation wastewater through the plant disposal recycling reuse and tailing pond overflow reuse "double cycle" comprehensive reuse to achieve the production of wastewater plant emissions.
Our main waste include waste gas, waste water, solid waste and hazardous waste, we have made a series of waste management system, emphasizing on the hazardous waste from the generation, collection, storage to the transshipment of the whole process of management,and build a recycling system for waste materials to improve the disposal and management system of waste materials.
We set targets related to environmental pollution emission to achieve "zero environmental pollution accidents" and "qualified rate of 100%".
