摘要
针对辛置煤矿2#煤层2-106回采工作面瓦斯超限问题,在U型通风系统的基础上,选用本煤层抽采、高位钻孔抽采相结合的技术方法降低工作面瓦斯浓度,使其保持在可控的范围内,确保2-106回采工作面U型通风期间不发生瓦斯超限事故,实现全矿的安全生产。
Aimed at gas overrun at No. 2-106 working face in 2e coal seam in Xinzhi Coal Mine, the gas drainage in current coal seam and the gas drainage by high-level drilling were com- bined to reduce gas concentration at working face under U-shape ventilation. The gas concentra- tion was kept in the controllable scope, and no gas overrun accident happened at No. 2-106 work- ing face during the ventilation, achieving the safety production in the whole coal mine.
