摘　　要：安全、高效、低成本地开发利用薄煤层资源对于许多老矿区的可持续发展具有重要的现实意义。通过对山东省部分地方煤矿在极薄煤层开采方面进行的探索研究，总结出一套倾斜短壁前进式开采、无人工作面中深孔爆破工艺和沿空留巷技术，是解决极薄煤层（0．37～0．40m）开采的行之有效的采煤方法，可最大限度地回收煤炭资源。It has important realistic meaning for many old mine areas＇ continuable development for how to extract the extremely thin coal seam resources safely, efficiently and low costly. The quest research in this aspect carrying on in Shandong province＇ s local coal mines was introduced in this paper. A series of effective mining methods for extremely thin coal seam（0. 37 -0.40 mm） mining has been summarized, i.e. , shortwall advancing mining method in the dip, medium- deep borehole blasting technique, entry reserved for next sublevel, etc. It has reclaimed the precious coal resources at biggest degree.
