摘要
针对同发东周窑煤业C5号层8103和山4号层8402综采工作面,通过合理确定放煤工艺,应用头、尾两巷安全出口畅通,改造乳化液泵站供液系统,提高采煤机牵引速度等关键技术,有效提高了工作面单刀产量,取得了良好而显著的成效。
This paper introduces the fully mechanized coal mining face of C5 layer 8103 and Shan4 layer 8402. The key technologies, such as improving the traction speed of the shearer and reforming the liquid supply system of the emulsion pump station, have been improved effectively.The yield of single knife has achieved good and remarkable results.
