Mine geological environment protection and restoration management in Qinghai Province

The geological environment protection of mines must run through the whole process of mineral resources development. It must adhere to the principles of “development in protection, protection in development” and “pre-existence prevention, governance in the event, and recovery afterwards”, and strict environmental protection standards for the development and utilization of mineral resources. Into management, to minimize the impact and damage of mineral resources development activities on the environment. Newly built (expanded) mines, production mines, and closed pit mines should be mine environmental protection and restoration work according to the requirements of different stages. In accordance with the principles of Yi Nong, agriculture, Yi Jian, Jianlin, Yicao, and grass, the land reclamation work will be carried out.

1. Newly built (expanded) mines must meet the environmental protection access conditions. When applying for a mining license, the applicant shall submit the mineral resources development and utilization plan, environmental impact assessment report, mine geological environment protection and comprehensive treatment plan, construction project geological disaster risk assessment report and soil and water conservation plan approved by the competent department. Land reclamation plan, etc. The implementation of the environmental protection one-vote veto system will not be approved for mining rights applications that have environmental impacts and are highly destructive or difficult to restore.

2, mining rights before applying for mining permits, to sign with the land and resources departments mine geological environmental responsibility, clear duties and responsibilities mine geological environment protection, in full accordance with the law deposited in environmental restoration margin. The mine geological environment restoration and treatment costs and land reclamation costs shall be included in the production costs in accordance with relevant regulations. Strictly implement the "three simultaneous" system of simultaneous design, construction and simultaneous production of mine construction and environmental protection facilities. If the environmental protection facilities are not accepted or accepted by the competent department, they shall not be put into production. At the same time set up for mine beneficiation plant must have a comprehensive utilization of tailings and governance programs.

1. The mining right holder must strictly follow the approved development and utilization plan, mine geological environment protection and comprehensive treatment plan, engage in mining activities and mine geological environmental protection, and earnestly fulfill the mine geological environment recovery and management obligations. Formulate relevant plans and measures to strengthen the environmental treatment of waste water treatment and long-term stacking of tailings slag during mining and beneficiation, and strive to achieve simultaneous restoration and treatment.

2. The mining right holder must strictly perform the land reclamation obligation in strict accordance with the approved land reclamation plan. Take effective measures to minimize the damage to land area, reduce the degree of damage, effectively protect cultivated land, especially basic farmland, and strive to achieve mining, protection, and reclamation.

(3) Closed pit mine

1. The closed pit mine shall submit the mine geological environment restoration and management plan. Before the open pit mine is closed, it is necessary to submit a closed pit report including the land reclamation implementation report, ecological restoration and secondary geological disaster management. Before the mine is closed, the closed pit report including the prevention and control of mine geological disasters and restoration and management shall be submitted.

2. Before the mine is closed or closed, it is necessary to strictly carry out environmental protection work such as land reclamation, ecological restoration, tailings pond protection, waste slag filling, and wastewater treatment according to the planned and prescribed time.

3. The land and resources management department shall, in conjunction with the relevant departments, inspect and check the geological environment restoration and resettlement of the closed pit mine, and meet the acceptance criteria to close the pit. If the mine geological environment restoration and land reclamation tasks are not completed or the requirements are not met, the mining rights restoration and restoration deposit and land reclamation fees of the mining right holder shall be recovered according to law, and the competent land and resources department responsible for mining registration shall be specially used for the mine. Geological environment restoration and land reclamation.

According to the impact of mine development on human settlements, industrial and agricultural production, and regional economic and social development, combined with the analysis of the geological environmental impact assessment of the province and the development trend of mine geological environment, the key governance areas of the mine geological environment are divided.

The key geological environment management area of ​​the mine refers to the area with high exploitation and utilization of mineral resources, serious damage to the geological environment of the mine, and great impact on economic and social development; state-owned large and medium-sized old mines and closed pit mines constructed before the liberation and planned economy periods cannot be defined. Responsible persons, areas of mines with serious environmental problems; areas where environmental problems caused by mineral development pose a serious threat to the lives and property of local people. A total of 26 key areas of mine geological environment management were planned, with a total area of ​​129,100 square kilometers, accounting for 17.99% of the total area of ​​the province.

In the key geological environment management area of ​​the mine, focusing on the unowned mine caused by historical legacy and loss of mineral rights, the key geological environment management project of the mine is taken as the carrier, and the national and provincial financial funds are actively pursued to carry out the restoration and treatment of the mine geological environment. Encourage and guide all kinds of social funds to participate in the restoration and restoration of the geological environment of the mine in various ways, such as the priority of the governor to obtain land use rights.

Third, the mine geological environment key governance project

(1) Principles of key governance projects

Adhere to the principle that the ecological environment damage within the direct visibility of the Sanjiangyuan area, urban areas, and important traffic trunk lines, famous scenic spots and tourist areas will be restored to the principle of sustainable restoration; insist on prioritizing the safety of human settlements, industrial and agricultural production, and regional economy. The principle of old mine management with great influence on social development, heavy harm and significant treatment benefits; adhere to the principle of rational layout, step-by-step implementation, highlighting key points and adapting to local conditions.

A total of 129 key geological environment treatment projects in the province were arranged, with a total area of ​​366.10 square kilometers, accounting for 28.70% of the total area occupied and destroyed by the province. The total land reclamation area was 156.02 square kilometers, accounting for the occupation of the province and destroying agricultural use. 29.99% of the total area. In accordance with the "first focus, then general" and prioritized, phased implementation ideas, completed in 2008 to 2010 and 2011 to 2015.

1, 2008 to 2010

Priority should be given to old mines that have a major impact on human settlements safety and economic and social development, are highly hazardous, and have significant effects after treatment. Mainly due to the loss of historical and mining rights, the main coal mine, closed pit gold mine and urban planning areas, ecologically fragile areas and closed traffic mines on both sides of the main traffic trunks are mainly treated. There are mainly gold and coal mines in Haibei, gold, multi-metals and coal mines in Haixi, gold deposits in Qingnan, brick and clay mines in Xining and Haidong. There are 70 planned treatment projects, with a restored area of ​​230.65 square kilometers and a land reclamation area of ​​89.94 square kilometers.

2. 2011 to 2015

Mines that can produce good social, economic and environmental benefits after governance will be dominated by closed-pit gold deposits in ecologically fragile areas, followed by radioactive mines and coal mines. There are mainly sand gold mines in the Qingnan and Qilian Mountains, brick and clay clay mines in the eastern region, and polymetallic and radioactive mines in the Huangnan and Hainan regions. There are 59 planning and control projects with a treatment area of ​​135.45 square kilometers and a land reclamation area of ​​66.08 square kilometers.

During the planning period, the total investment of mine geological environment restoration and management in the province was 2.871 billion yuan, including 1.344 billion yuan during the period from 2008 to 2010 and 1.473 billion yuan during the period from 2011 to 2015. The fund raising of the mine geological environment restoration and treatment project is mainly based on the central government's financial input, which requires 80% of the central funds and 20% of the local financial self-raised funds.

The principle of investing in capital investment is: state-owned mines with historical legacy, closed, no clear responsible persons and serious environmental damage, with state investment as the mainstay. In the planned economy period, the geological environment problems of the historical mines remaining in the state-owned mines that are still being produced are in the form of government subsidies and capital contributions shared by enterprises. For the mine geological environment problems newly generated in the mines currently in the production stage, the developers shall undertake the tasks of environmental protection and restoration and management.

Through the implementation of the key geological environment management project of mines, we strive to achieve a recovery rate of 20% and 30% of the geological environment of the remaining mines in 2010 and 2015, and strive to achieve a land reclamation rate of 20% and 30%. Strive to achieve the national average level of the restoration rate of the geological environment and the land reclamation rate of the mines in the past 2020.

Fourth, improve the management system and operational mechanism

(1) Establishing a leadership responsibility system for mine geological environment protection

Establish and improve relevant laws, regulations and rules for mine geological environment protection, and clarify the legal responsibility system for all aspects of mine geological environment assessment, monitoring, protection and restoration. Establish the administrative head responsibility system for mine geological environment protection, implement the administrative department responsibility system and assessment system for mine geological environment protection, and include the target tasks of mine geological environment restoration and management in the government's term of office and annual work targets for assessment.

Based on the principle of prioritization, highlighting key points, and step-by-step implementation, starting from key mines, conducting key mine geological environment surveys and land reclamation monitoring and evaluation work, providing reliable basic information for mine geological environment protection and restoration and land reclamation work .

Gradually implement the mine geological environment monitoring, forecasting and early warning reporting system. The construction of the mine geological environment monitoring network will be carried out with the focus on salt lakes, coal and large exposed mines. Through the establishment of mine geological environment monitoring demonstration points, accumulate experience, and gradually establish and improve the province's mine geological environment monitoring system.
