为了控制亭南煤矿103综放面主采8#煤层的自燃现状。根据亭南煤矿103综放工作面实际情况,提出了结合综放面的气体分析数据和工作面采空区的三带分布状况,在停采撤架期间对两道、停采线和采空区采取压注轻质膏体、高分子胶体、复合胶体等材料的综合防灭火技术措施,并加强通风系统管理,减少工作面风量,保障了工作面的顺利撤架。结果表明:利用停采撤架的防灭火技术在亭南煤矿的应用是行之有效的,可靠的。
For control spontaneous combustion of 8# layer coal of fully mechanized caving face No.103,the condition of the working face is introduced.Based on the gas analysis data of fully mechanized caving face and the distribution of "Three belts" in gob,the combined fire prevention measure to two tunnels,mining suspending line and gob during mining suspending and supports withdraw is raised,which is mainly using light grease,high polymer gel and compound gel.Reinforcing ventilation system management and decreasing working face ventilation are also conducted to guarantee the safety of working face.It indicates that the combined fire prevention techniques are effective and reliable during mining suspending and supports withdraw.
