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。
針對辛置煤礦2＃煤層2-106迴採工作麵瓦斯超限問題，在 U 型通風繫統的基礎上，選用本煤層抽採、高位鑽孔抽採相結閤的技術方法降低工作麵瓦斯濃度，使其保持在可控的範圍內，確保2-106迴採工作麵 U 型通風期間不髮生瓦斯超限事故，實現全礦的安全生產。

Aimed at gas overrun at No. 2-106 working face in 2 # 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.
