摘要
为了有效地防治煤巷及抽采巷自燃发火,通过对己15-14140机巷煤层自然发火特点、煤层成分、水分、孔隙率等内在因素和水力冲孔、水力压裂、断层附近造成的巷帮煤柱承压、煤体破碎、季节及压差变化等外在因素进行分析,提出了注阻化黄泥浆、水泥浆、及时封闭抽采残孔、巷帮刹实充填等综合防治措施。
In order to prevent and control the spontaneous ignition of coal lane and extraction lane, this article puts forward comprehensive prevention and control measures including casting inhibitor yellow mud, cement paste, timely closing extraction hole and lane side solid packing through the analysis of the internal factors including spontaneous ignition characteristics, component of the coal seam, moisture and porosity and the external factors including hydraulic hole, hydrofracture, lane side coal pillar pressure bearing and coal body fragmentation, and seasons and pressure deviation of F 15-14140 lane coal seam.
