(January 6, 2005 the State administration of work safety, the State administration of coal mine safety supervision Bureau announced come into force on the date of promulgation, 21st) first as a follow-up after the first mining, monitoring, wind and fixed the gas control policy, State-owned King the occurrence of gas accident in coal mine, according to the work safety law, the coal mine safety supervision regulations and other laws and administrative rules and regulations, this provision is enacted.
    The second State-owned coal mines (including State-owned coal mining enterprises and mines, hereinafter referred to as mine) to set up gas control agencies and professional and technical personnel, establish accountability and management system of gas control, implement governance funding.
    Chief of coal mine gas control is first responsible person; Chief Engineer technology responsible for gas control in coal mine, responsible for the Organization to control gas and technical safety measures, responsible for funding arrangements.
    In charge of coal mine safety Administration Deputy supervision responsibility for gas control; other administrative Deputy in charge of programmes, measures of gas control in the field of implementation.
    Head of the coal mine will be on duty on the day of the full responsibility for work safety, must grasp well the number of discovered gas hazards must take immediate measures to deal with.
    High gas mine coal and gas outburst in charge should be rotated every six months to the local coal mine safety watchdog and gas control in coal mine safety supervision Organization report. Third coal mine methane classification system must be established.
    Identification of coal mine gas levels in each year must be carried out in accordance with the regulations.
    Appears in coal mine gas dynamic phenomenon, must be reported within 24 hours of local coal authority and the coal mine safety supervision organization, and timely application has the qualifications prescribed by the State certifying agency for identification shall not be undeclared.
    Clear gas grade gas dynamic phenomenon has occurred, but not mine, since the required gas should be completed within 60 days from the date of appraisal work, applications for identification in accordance with mine management. The fourth non-job of disallowed gas concentration in coal mine.
    Find jobs of disallowed gas concentration should be traced.
    Mining and other work sites in the airflow when the gas concentration reaches 1%, you must stop using the electric drill; when the gas concentration reaches 1.5%, you must stop working, cutting off power supplies, evacuate, for processing.
    Near the blast site within 20 metres of gas concentration in the air is 1%, no blasting blasting operations you must perform "a gun seized three" and "three interlocking" shooting system.
    The fifth must implement the provisions of the gas drainage in coal mine.
    The provisions of the mine safety regulations mine gas drainage system should be established, must be gas drainage, establishment of permanent ground gas drainage system or temporary gas drainage system in underground, and after implementing the first pick.
    Mine protective layer must first be mined, not capable of protection layer mining conditions must be pre-pumping outburst coal seam, and ensure the roughing time and effectiveness.
    Sixth article must establish a reliable monitoring system of coal mine. High gas outburst mine high gas area of low gas mine, mine safety monitoring system must be equipped with reliable operation, installation, use and maintenance of systems and sensors, you must meet the requirements of the provisions of the mine safety regulations; monitoring center on duty station should be established within the mine control room, must be equipped with safety training qualified professionals on duty 24 hours.
    Officer on duty when he found the underground gas alarm, must be dealt with immediately and found large areas in underground gas limited, must immediately power withdrawn people.
    Article seventh coal mine ventilation capacity must be approved each year to ensure fan actual ability, no hyper-ventilating ability to organize production.
    Approved mine ventilation capacity should be reported to provincial coal Department for review, the provincial coal mine safety supervision organization record.
    Appears under the coal mine wind overload, gas concentration exceeding limits and unreasonable series ventilation equivalent Super ventilation capacity to produce ultra ventilation capacity production of mines, mining areas, face, must immediately cut their production, to adjust the layout and ventilation systems, within the approved mine ventilation capacity for production fell to.
    High gas outburst mine safety regulations shall be strictly in accordance with the provisions of the arrangement of mining, production and prevent unreasonable set campaign production.
    Eighth article must establish and implement of coal mine gas detection system, and take prevention measures.
    All jobs in coal mine locations and likely to build up in gas stations must be fixed, regular inspection of gas and gas inspection program and to take measures to prevent gas inspectors missed. Coal and gas outburst in gassy mines, mines, mining in high gas area of low gas mine, there must be a dedicated gas inspectors to check Ben gas.
    Gas inspectors found the ultra limited has the right to stop work immediately, evacuate.
    Outburst of coal and gas outburst must take risk prediction and outstanding prevention outburst measure, control measures of verification and safeguards, "four in one" comprehensive outburst-prevention measures, and strengthening gas geology prediction.
    Outburst of new levels and new mining areas, expose prominent must make prevention and control of coal seam outburst seams in a crosscut design and approval by the technical director.
    Outburst prohibited the use of overhead line electric locomotive has been used, and corrective action must be completed within 1 year; during the corrective action, safety measures must be taken.
    Nineth coal must be equipped with an independent ventilation system, the level of production and mining area must be separate ventilation. High gas outburst, each district must be set to at least 1 special air; the main liaison between the inlet and return airway lanes must be building a permanent wall, you need to use, you must install 2 interlocking positive throttle and reverse throttle 2.
    Mining district, the air must be run through the entire mining area, prohibited a for airway, for some air. Auxiliary fan must be managed by a designated officer to ensure the normal operation. Do not use more than 3 local fans while 1 in heading face to the wind.
    Using 2 sets of auxiliary fan air supply to the same place, must be accompanied by wind electricity closed. Tenth must strengthen the caving in coal mine management.
    Projecting coal seam outburst and threats, is strictly prohibited on top coal caving mining method was used. Caving must formulate fire prevention, dust-proof, gas-proof, safety measures such as roof control and design based on geological features of seam caving coal mining; coal (waste) stuck on coal port, the explosive is strictly prohibited.
    When there is a gas or coal dust explosion hazard, do not pick top-coal blasting. On top coal caving mining method was used when mining easy spontaneous combustion and spontaneous combustion of coal, must be prepared to prevent spontaneous combustion in goaf of design, establishment of fire monitoring system, the concentration of carbon monoxide sensors are configured, and to take effective and comprehensive measures to prevent spontaneous combustion. Found in underground spontaneous combustion, you must include all possible evacuations in the area threatened by the fire, take measures for processing.
    Hazard is not completely eliminated, no resume production.
    These provisions come into force on the date of promulgation.
