摘　　要：急倾斜煤层走向长壁工作面在开采过程中,松软煤层及软弱底板问题极大地限制了煤矿智能化开采的飞速发展,其产生的煤壁片帮和底板破坏、滑移问题极易造成人员伤亡、设备损坏等安全生产事故,给煤矿安全生产带来极大的威胁。对急倾斜煤层走向长壁工作面的松软煤层及软弱底板产生的原因进行分析,并对其防治工艺进行探讨,为类似地质条件下复杂煤层开采提供借鉴。During the mining process of the steep coal seam longwall working face,the problems of soft coal seam and weak floor greatly limit the rapid development of intelligent mining in coal mine.The damage and sliding problems of coal wall caving and floor are easy to cause casualties,equipment damage and other safety accidents,which pose a great threat to coal mine safety production.Analyzed the causes of soft coal seam and weak floor of steep coal seam longwall working face,and discussed the prevention technology,which can provided reference for other similar geological conditions of complex coal seam mining.
