保护层开采不充分区域突出煤层工作面消突技术实践

Outburst coal seam working face outburst elimination technology practice in insufficient protective seam mining area

针对保护层开采不充分区域突出煤层消突难题,以冀中能源峰峰集团大社矿92622工作面为实例,结合现场管理经验,制定了保护层开采不充分区域突出煤层工作面消突措施方案,并对消突措施落实后的应用情况进行了分析,结果表明,该措施保证了工作面回采期间瓦斯含量符合规定,达到安全回采工作面的目的。

Based on the outburst elimination problem in insufficient protective seam mining area, 92662 working face of Dashe Mine in Jizhong Energy Fengfeng Group was taken as example, combined with management experience on the site,outburst elimination measures in insufficient protective seam mining area was settled, the corresponding application of outburst elimination was analyzed, the result showed that the technology ensured the gas content meeting the standards and safe recovering mining.
