(October 25, 2006 national safety supervision management General makes 10th, announced since January 1, 2007 up purposes) a, and will coal mine security procedures (original national safety supervision authority straddling national coal mine security monitored Council makes 16th,, following referred to procedures) 68th article provides of: "used put top coal mining method mining Shi, must comply with following provides: (a) must according to seam geological features prepared put top coal mining design.
    (B) the face must meet the following conditions: 1. No coal (Rock) and gas (carbon dioxide) outburst; 2. top-coal and roof-coal caving or take measures such as presplitting blasting in time after collapsing and roof caving goaf of filling height of the taller-than-coal mining.
    (Three) must for seam of mining technology conditions and put top coal mining process of features, on fire, and dust, and anti-gas, and put coal step from, and put coal order, and mining put parallel relationship, and roof control, and bracket selection, and end head support nursing, and cut eye spread surface, and bracket installation, and initial put top (coal), and face ending and the bracket back withdrawal, developed security technology measures. (Iv) coal (waste) stuck on coal port, no explosion; there is gas or explosion danger, do not pick top-coal blasting. "Modified for:" used put top coal mining Shi, must comply with following provides: (a) mine first times used put top coal mining, or in seam (gas) assigned save conditions changes larger of regional used put top coal mining Shi, must according to roof, and seam, and gas, and natural angry, and hydrological geological, and coal dust explosion sex, and impact to pressure, geological features and disaster risk prepared mining design, mining design should by experts argument or delegate has related qualification units evaluation Hou reported to the group or County above coal management sector approval,
    And reported to the coal mine safety supervision organization record.
    (B) for the coal seam mining technology of top-coal caving mining technology with conditions and characteristics must be gas, fire-proof, dust-proof, waterproof, coal mining technology, roof supports, mining and face early closure and other security measures. (C) by presplit blasting of hard roof or weakening the hard top-coal processing, should be carried out in the face of mining area and specific safety measures.
    Is prohibited by blasting in working face coal, and stuck in the roof caving of coal (waste rock).
    (D) high gassy and easy spontaneous combustion coal seam, should be taken with gas pre-drainage methods of integrated measures and comprehensive fire prevention and extinguishing measures to ensure the little gas content in coal seam in 6m3/t or surface maximum wind speed is not more than 4.0M/s.
    (E) face is strictly forbidden the use of wooden pillars, metal pillars support methods.
    Any of the following circumstances, prohibited the use of single hydraulic prop caving coal mining: (a) the angle greater than 30 ° of the seam (horizontal top-coal caving in steep inclined thick seam).
    (B) the burst seams.
    Any of the following circumstances, no top-coal mining: (a) the average coal seam thickness is less than 4m.
    (B) a ratio greater than 1:3.
    (C) mining areas or mining rates up to mine design specifications.
    (D) the seam of coal (Rock) and gas (carbon dioxide) danger of outburst.
    (E) difficult, hard top-coal caving of hard roof, and take measures so caving still poor roof caving bash the height of not more than coal mining. (F) hydro-geological conditions, likely after mining and surface water, strong aquifer and water conduction of old kilns. "Second, the 158th of the procedures provided for in article:" high gas mine coal (Rock) and methane outburst mines, must be equipped with mine safety monitoring and control system. No equipment of mine safety monitoring and control system for mine roadway and semi-coal rock lane and gas emission of rock roadway drivage, must be equipped with methane, wind blocking device or methane and wind breaker electric locking device. No equipment of mine safety monitoring and control system of rock drivage working face gas emission-free, and must be equipped with wind blocking device. No equipment of mine safety monitoring and control system of mine face, must be equipped with methane power meter. "Is revised as follows:" all mines be equipped with mine safety monitoring and control system. Mine safety monitoring and control system installation, use and maintenance must comply with the requirements laid down in this regulation and related. "Third, this decision as of January 1, 2007.
                                                                                                            Other provisions, in accordance with the original implementation of the procedures.
