摘要 针对平煤十矿丁5,6卸压区域内的煤层和未卸压区域内的煤层区域制定合理的防突措施,并对区域措施效果进行了检验和验证。同时对局部煤层的情况实施了综合防突措施,最后对反向风门、压风自救系统、避难硐室、爆破作业等安全防护措施进行了论述。 In order to make the outburst prevention measures in 5 & 6 coal seams of D group be more effective, the paper makes reasonable measures for outburst prevention measures accord- ing to the coal seams in pressure relieving zone and pressure non-relieving zone in 5 & 6 coal seams of D group, and conducts the inspection and verification on the regional measures effects. At the same time, it conducts the comprehensive outburst prevention measures on local coal seams, and then elaborates the safety protection measures of reversed damper, self-rescue com- pressed air system, refuge chamber and blasting operation.
