摘要
嵩山煤矿克服偃龙矿区"三软"煤层压力大、来压快等不利条件,通过对综采工作面回撤技术的研究与实施,大大缩短了回撤工期,实现了安全、快速、高效回撤的目的。
In Songshan Coal Mine, Some adverse conditions were overcome in ＂three soft＂ coal seam, such as large pressure in coal seams, to pressure fast. Through the research and practice of withdraw technology at the fully mechanized coal face, the withdraw period of 2201 fully mechanized coal face was greatly shortened. The safe, fast and efficient retracement purpose at the fully mechanized coal face was realized.
