Detailed rules for prevention and control of rockburst

Rock burst refers to the dynamic phenomenon that coal (rock) around coal mine roadway or working face is suddenly and violently damaged due to the instantaneous release of elastic deformation energy, which is often accompanied by instantaneous displacement, throwing, loud noise and air waves of coal (rock).

Rock burst can be classified according to the main body and load type of elastic energy release of coal (rock), and targeted prevention measures can be taken for different types of rock burst to realize classified prevention.

Establishing "Zero Impact" Target Management System in Coal Mine

Rock burst mines should establish the concept of disaster prevention in advance, strengthen the "zero impact" target management without casualties, roadway damage and equipment damage, establish the "zero impact" target management system in coal mines, and strengthen the on-site management of monitoring and early warning and comprehensive impact prevention measures. In accordance with "regional measures first, local measures follow up, warning signs appear, measures are taken to solve the danger, dynamic phenomena appear, and measures are taken to solve the danger, and there are hidden accidents and mining operations are not allowed" In view of the key factors such as deep mining depth, thick hard roof and geological structure, comprehensive regional scour prevention measures should be taken to prevent rock burst from the source. Through risk prediction, monitoring and early warning, local preventive measures such as strengthening support and relieving pressure are taken in the dangerous area of rock burst. If dynamic phenomena or high-risk monitoring and early warning signals still appear after taking regional and local comprehensive anti-scour measures, comprehensive anti-scour measures must be further strengthened to ensure that the measures are effective, otherwise mining operations may not be carried out.

First, strengthen the prevention and control measures of coal mine rock burst

Rockburst mines shall regularly carry out rockburst risk assessment and hidden danger investigation, establish management systems such as risk assessment, scheme design and implementation, project quality control and hidden danger investigation, clarify the main responsibilities of rockburst prevention scheme design (improvement), implementation (execution), inspection (acceptance) and organization (coordination), and strictly review and implement it. For moderate and above rockburst danger areas with hard roof and geological structure as the main disaster-causing factors, effective prevention measures should be formulated and implemented for the main disaster-causing factors. To evaluate the coal mining face with moderate or above impact risk, long-distance power supply and liquid supply (more than 500 meters away from the coal mining face) should be adopted, and hydraulic supports should be used for the upper and lower exits and roadway advanced support. Install video surveillance at the tunneling face, the upper and lower exits of the coal mining face or the advance support roadway and coal seam drilling construction site in moderate and above impact danger areas to solve the danger. When it is found that the monitoring data exceeds the critical index of rockburst risk early warning, the personnel irrelevant to the scour prevention operation should be evacuated, the risk relief and pressure relief work should be carried out, and the scour prevention scheme should be implemented.

Two, orderly carry out the demonstration mine construction of rockburst prevention and control.

Coal-producing provinces (autonomous regions and municipalities) with rockburst mines can refer to the Basic Requirements for the Construction of Demonstration Mines for the Prevention and Control of Rockburst in Coal Mines (see Annex for details), adhere to the combination of incentives and constraints, take enterprises as the main body and the government as the guidance, strengthen planning, improve relevant supporting policies, and stimulate the enthusiasm and creativity of coal mining enterprises in building demonstration mines. First, select typical mines with good basic conditions and high management level, organize relevant experts to conduct technical consultation and guidance, study and formulate a construction scheme of demonstration mines for rockburst prevention and control suitable for the characteristics of this mining area, study, test and popularize advanced and applicable technologies, equipment and typical experience, carry out the construction and intelligent construction of typical demonstration mines for rockburst prevention and control, and build a demonstration mine with "sound management system, optimized mining deployment, supporting anti-scour equipment, effective monitoring and early warning, reliable local measures and safe construction operation". Through typical demonstration and orderly promotion, a number of demonstration mines with outstanding effects and strong driving force will be built to prevent and control rock burst in coal mines. On the basis of summarizing the experience in the construction of demonstration mines for the prevention and control of rockburst, the regulations and standards for the prevention and control of rockburst in coal mines are improved, and the prevention and control technologies, equipment and typical practices of rockburst in coal mines are popularized, so as to effectively prevent the rockburst accidents in coal mines.

Detailed rules for prevention and control of rock burst in coal mine

Rule number two These rules are applicable to the prevention and control of rock burst in coal mining enterprises (coal mines) and related units.

Rule three. The main person in charge (legal representative and actual controller) of a coal mine enterprise (coal mine) is the first person responsible for the prevention and control of rockburst, and is fully responsible for the prevention and control work; Other responsible persons shall be responsible for the prevention and control of rockburst within the scope of their duties; The chief engineer of a coal mine enterprise (coal mine) is the technical person in charge of the prevention and control of rock burst, and is responsible for the prevention and control technical work.

Article 4? The cost of rock burst prevention and control must be included in the annual safety cost plan of coal mining enterprises (coal mines) to meet the needs of rock burst prevention and control.

Article 5? Rock burst mines must prepare emergency plans for rock burst accidents, and organize emergency plan drills at least once a year.

Article 6? Rock burst mine must establish safety technology management system, post safety responsibility system, prevention training system, accident reporting system and other work norms.

Article 7? Encourage coal mining enterprises (coal mines) and scientific research units to carry out research and scientific research on the prevention and control of rockburst, develop and popularize the use of new technologies, new processes, new materials and new equipment, and improve the level of rockburst prevention and control.
