摘　　要：对于煤层倾角大的工作面,普通的综采设备在回采过程中,遇到诸多技术上的难题。城山煤矿在遇到大倾角的地块时,首先采取了俯采工作面调整为俯倾斜采煤工作面,并在回采过程中对采煤机进行了改革,突破了技术难关,实现了安全开采。With regard to the face of big slope angle seams,the ordinary fully mechanized mining equipments meet many difficult technical problems.In Chengshan Coal Mine,the big slope angle land parcel is met,the downward mining face is adjusted to the downward slope mining face.In the mining process,the miner is improved,the technical difficulty is broken out,the safe mining is realized.
