摘　　要：煤层巷道过断层破碎带时,巷道掘进受断层控制作用明显,常规的巷道支护技术和施工方法很难奏效。通过对煤层巷道综掘工作面过断层技术的探索研究以及在姚桥煤矿7502B运输顺槽的实践,总结出了切实可行的综掘工作面过断层技术,为综掘工作面过断层破碎带提供了一些可以借鉴的经验。In the process of crossing fault fracture zone, roadway excavation is obviously controlled by faults due to the complicated geological conditions and the conventional roadway support technology and construction meth- od dont work. Through study on the technology of crossing faults in fully mechanized working face and practice on conveyor gateway in Yaoqiao Colliery, the author concludes the practical technology of crossing faults and provides experiences for crossing fault fracture zone in fully mechanized working face.
