41 law enforcement teams, 5 unmasking groups, 36 hard measures, Shanxi carried out a "dragnet" mine risk hidden danger inspection

After the "11·16" major fire accident occurred in the Yongju coal industry in Luliang, the Shanxi Bureau of the State Mine Safety Administration immediately organized the "double investigation" of fire hazards up and down the mine, effectively strengthened risk identification and control and hidden danger investigation and rectification, effectively resolved and eliminated all kinds of fire risks in mining enterprises, and resolutely prevented and contained major accidents.

First, strictly prevent fires in coal mines. Keep an eye on the 79 coal mines in the province that are prone to spontaneous combustion; keep an eye on the coal mines that are mined by the top coal caving process in northern regions such as Datong, Shuozhou and Xinzhou; keep an eye on the coal mines that are currently mined in Jinzhong, Yangquan and other regions where 15# coal seams are covered with unminable coal seams containing phosphorus; and urge coal mining enterprises to implement comprehensive fire prevention measures such as spraying inhibitor, injecting nitrogen and grouting. Strengthen the monitoring of toxic and harmful gases in goaf and the prediction and prediction of spontaneous combustion in coal seam, and strictly prevent spontaneous combustion in goaf.

Second, strict fire operation and polymer material management. Urge mining enterprises to strictly examine and approve underground fire operation, prohibit illegal electrical and gas welding operations in the mining face and return air flow, in the shaft and main roadway fire operation must formulate safety measures and emergency plans, evacuate the affected area of the operator in advance, by the mine leaders on the spot, supervision throughout the whole process, to ensure that nothing goes wrong; At the same time, strengthen the management of polymer materials, conduct comprehensive screening of polymer materials in use, and prohibit non-flame retardant and unqualified polymer materials from entering the well.

The third is to prevent fire caused by improper use of underground mechanical and electrical transportation equipment. Deeply drawing lessons from the "9·24" major fire accident in Shanjiao Coal Mine, Guizhou Province, we continued to carry out special rectification of belt conveyor transportation in coal mines, continued to map out the province's underground use of belt conveyor and belt manufacturers, and established a ledger list for management. Urge mining enterprises to focus on the "disease-bearing" operation of mechanical and electrical transportation equipment and tape, unreliable flame retardant performance of tape, serious wear and tear of tape is not handled in time, various types of protection are not complete, carbon monoxide and smoke sensors are not effective and other prominent problems that are easy to cause fire.

Fourth, strict fire prevention management of ground buildings (structures). In view of the frequent occurrence of fire accidents in winter, local governments are urged to organize relevant departments to immediately organize and carry out full coverage fire prevention checks on mine wellhead rooms, joint buildings centered on wellheads, and ground buildings near air intake wellheads, set fire doors, fire fighting equipment and smoke alarm devices in strict accordance with regulations, and set safety exit signs; Effective measures should be taken to prevent fireworks from being introduced into the well for buildings connected with the well head, such as joint buildings. No fireworks are allowed within 20 meters near the wellhead room and the ventilation room, and no illegal overlapping electric heating is allowed.

Fifth, strengthen fire risk monitoring and early warning. Urge mining enterprises to install carbon monoxide and smoke sensors in key locations such as underground mining operations, closed places and return air flows in strict accordance with regulations. Dispatchers, security monitoring system check-in personnel and on-site operators should stop operations and withdraw personnel as soon as possible when carbon monoxide and smoke alarm or abnormal alarm is found, and production can be resumed only after risks and hidden dangers are eliminated. Smoke alarm devices should be installed in wellhead rooms, densely populated places on the ground and other places to evacuate people in time.

Shanxi Bureau 36 coal mine supervision and law enforcement teams, 5 non-coal mine mountain supervision and law enforcement teams were dispatched, and 36 hard measures were taken to carry out special investigation and rectification of major accident hidden dangers. Urge the emergency management departments of cities and counties to promptly carry out a "dragnet" inspection of hidden risks in combination with the relevant requirements of the comprehensive rectification of mine safety production and the special investigation and rectification of major accident hidden dangers. The establishment of five covert investigation and covert visit groups, led by the bureau leadership, fragmentation of the province's dynamic investigation of the safety of the "insecure mine" to carry out law enforcement inspections, the comprehensive use of production rectification, upper limit punishment, notification of exposure, interview reminders, accountability and other means to maintain the "fight against non-violation" high-pressure situation. At the same time, the law enforcement and service guidance will be combined, and the supervision and law enforcement departments will be organized to carry out assistance and guidance for the "insecure mine", and the "one mine and one policy" will help mining enterprises solve prominent problems in safety production.
