Opinions on further strengthening the work of mine safety production

8. Improving the ability to support scientific and technological innovation Strengthening the construction of science and technology support systems for mine safety. Strengthen research on the prevention and treatment of major mining disasters, organize major key technology research. Promote the development and application of mine information technology, intelligent equipment and robots. A number of major science and technology projects related to mine safety were implemented. To study and promote the construction of a national key laboratory in the field of mine safety.

3. Forestall and defuse major security risks

(9) Improve the safety management system in mines. Mining enterprises should improve the safety production standardization management system with safety risk classification control and hidden danger investigation and management dual prevention mechanism as the core. Strictly carry out risk identification and assessment and implement hierarchical control, regularly carry out full coverage of hidden danger investigation and management, establish a list of hidden risk accounts, and implement closed-loop management. Mine safety supervision and supervision departments at all levels shall promote enterprises to effectively improve the quality of risk and hidden danger investigation and rectification, establish a major hidden danger management and supervision system, track supervision before major hidden dangers are eliminated, and supervise the rectification and cancellation. Where major hidden dangers still exist or accidents occur due to inadequate investigation and rectification, enterprises and relevant responsible persons shall be investigated for their responsibilities according to law.

10. Strengthening disaster management. Mining enterprises shall identify hidden disaster factors and implement regional management and advanced treatment of major disasters such as coal and gas outburst, rock burst and water damage. The evaluation of coal mine disaster levels shall be included in the scope of safety testing and inspection, and the evaluation results shall be publicized in a timely manner. Standardize the management and verification of coal mine production capacity. Where the slope height of the stope and dump of a metal and non-metal open-pit mine is greater than 100 meters, the stability analysis of the slope shall be carried out year by year. Where the volume of the goaf of a metal and non-metal underground mine exceeds the prescribed amount, a special stability assessment shall be carried out in a timely manner. The quality inspection of the flood discharge structure of the tailings pond shall be carried out once every three years.

(11) Strict safety management of equipment and facilities. We will improve the review, issuance and supervision mechanism of safety signs for special equipment in underground mines. Regular safety and reliability inspection shall be carried out on in-use equipment and facilities that have obtained safety marks for underground special equipment. Establish a intelligent supervision platform for the whole life cycle of mining safety equipment, and implement a safety responsibility system for mining equipment.

(12) Standardize the management of non-coal mine outsourcing projects. Non-coal mining enterprises are uniformly responsible for the safety management of outsourcing engineering construction units. It is strictly prohibited to outsource special blasting operations in metal and non-metal underground mines. The number of contracting units for excavation projects of metal and non-metal underground infrastructure construction shall not exceed 3. The number of contracting units for mining projects of large and medium-sized metal and non-metal underground production mines shall not exceed 2, and the number of contracting units for mining projects of small metal and non-metal underground production mines shall not exceed 1, and contracting units shall not subcontract or subcontract mining projects and blasting operations. The contractor shall dispatch the project leader, technical personnel and special operation personnel to the project department; The person in charge of the project and the technical personnel shall have a secondary school degree or above in mining related majors or a professional title of intermediate or above, and shall not take part-time jobs in other mines. Strive to the end of 2025, production mines to establish their own mining (stripping) construction team or entrust with the appropriate conditions of the overall management of enterprises.

(13) Strengthen safety control in mines that have stopped production. A mine that has stopped production for rectification shall formulate a rectification plan, limit the number of people going down the well in a single shift, control the number of people at the same operation site within 10, and report to the mine safety supervision and supervision department before rectification operations can be carried out. Local governments and relevant departments shall observe coal mines for rectification of suspension and suspension of production, observe or inspect other mines for suspension and suspension of production, and carry out inspection and acceptance of resumption of work and production in accordance with regulations. If construction and production continue to be organized during suspension and suspension due to inadequate supervision and inspection, the enterprises and relevant responsible persons shall be seriously investigated for responsibility according to law.
