摘　　要：落差较大的断层,严重影响采煤工作面的安全生产。逆断层在永夏矿区较为罕见,车集煤矿2902工作面切眼为矿井首次揭露大落差逆断层,通过对大落差逆断层回采技术难题研究分析,对工作面爆破机理及效果反向分析总结,对综采工作面爆破规律摸索,优化了爆破参数及爆破防崩措施;合理控制回采层位,减少了破岩量;制定了托顶煤控制措施,有效实现了安全快速通过逆断层,对类似构造煤层开采具有较强的参考价值。The large drop reverse fault seriously affects the safe production of coal mining working face.The reverse fault is rare in Yongxia mining area.The technical difficulties of large drop reverse fault mining in fully mechanized mining face were firstly studied and analyzed in the 2902 working face of Juji coal mine.Through the reverse analysis of the blasting mechanism and effect,the blasting law of fully mechanized working face was explored and the blasting parameters were optimized.Reduction of the rock breaking amount was achieved due to reasonable control of the mining level.The control measures of supporting roof coal were formulated,which effectively realizes the safe and rapid passage through the reverse fault,and has a strong reference value for the mining of similar tectonic coal seam.
