摘　　要：针对潞宁煤业31101综采薄煤层工作面回采过程中受冲刷带等复杂地质条件的影响,造成的回采困难、成本增加等问题,分析总结了当前常用薄煤层工作面过冲刷带的技术及其适用条件,充分考虑薄煤层工作面过冲刷带选择技术的各种关键影响因素,科学合理地选择了松动爆破技术辅以采煤机截割技术过冲刷带的组合方式,并对松动爆破技术的炮孔布置及薄煤层截割设备进行了选型,为工作面过冲刷带提供了技术指导。实践证明:采用松动爆破及采煤机截割组合技术,不仅使工作面顺利通过了大规模冲刷带,而且为矿山多回收了超过6×104t煤炭,取得了较大的经济效益及社会效益,为后续矿山实际生产带来了突破性的指导意义,也为同行业及类似矿山提供了技术指导。In response to the complex geological conditions such as scouring zones during the backstoping process of the 31101 fully mechanized thin coal seam working face of Luning Coal Industry Co.,Ltd.,which have caused difficulties in backstoping and increased costs,this paper analyzed and summarized the current commonly used techniques and their applicable conditions for crossing the scouring zone in thin coal seam working faces,fully considered various key influencing factors of the selection technology for crossing scouring zone in thin coal seam working faces,scientifically and reasonably selected the combination method of loose blasting technology supplemented by coal mining machine cutting technology for crossing scouring zone,and selected the blasting hole layout of loose blasting technology and thin coal seam cutting equipment,providing technical guidance for crossing scouring zone in working faces.The practice proves that the combination of loose blasting and coal mining machine cutting technology not only enables the working face to smoothly pass through large-scale scouring zones,but also recovers more than 6×104 t of coal for the mine,achieving significant economic and social benefits.This has brought breakthrough guidance to the actual production of subsequent mines and also provided technical guidance for the same industry and similar mines.
