易自燃煤层特殊条件下综放开采工作面防火技术研究

Researches of the Fire-preventing Measures for Comprehensive Mining Coal Face at the Spontaneous Combustion Coal-seam under a Special Condition

分析了耿村矿１３０１工作面易自燃煤层特殊条件下综放开采工作面自然发火的危险性；探讨了因采空区漏风而引起的工作面自然发火的防治措施．经现场实施研究表明，均压通风、低风量供风、加快工作面推进速度的综合防火技术，成功地防止了自然发火，保证了综放开采工作面的安全生产．

The occurrences of the spontaneous ignition of the comprehensive mining coal face at the spontaneous combustion coal-seam under a special condition from the 1301 face in Gengcun coal mine has been analysed. In order to prevent the spontaneous ignition at the working face, which caused by the air leakage in the goaf, the comprehensive fire-preventing measures are adopted for balanced-pressure ventilation, low-volume air supply, and the speed_up tunnelling at coal face. The testing performances at worksite shows that the measures are both practical and effective for preventing the spontaneous ignition. Therefore, the safety-production in coal mines have been insured.
