摘　　要：根据郭二庄煤矿22208工作面地质条件,研究了三软煤层条件下大倾角综采技术。对开采过程中出现的技术难题,通过研究其机理,进而采取相应的安全技术措施,顺利地实现了大倾角仰斜开采,同时,也拓宽了综采工艺的适用范围。According to geological conditions of 22208 coalface in Guoerzhuang mine, combined mining tech nology under large inclined angle ＂three soft＂ coal seam condition has been studied in this paper. Based on the technology problems during mining process, corresponding safety technical measure by studying its mechanism have been taken, and large inclined angle rise mining has been realized successfully. At the same times, the applicable scope of combined mining technology also has been expanded, which has accumulated valuable experience for mining other similar coal seam in mine.
