大倾角软煤层综采工作面矿压显现规律研究

Study on strata behavior regularity of step soft seam fully mechanized coal face

通过对平煤集团十三矿己15- 17煤层综采分层和放顶煤工作面矿压观测资料进行分析和比较研究 ,揭示了大倾角软煤层条件下采用分层开采、放顶煤开采工作面支架受力及矿压显现的基本规律 ,对于加强综放工作面控制、推广应用综放技术有十分重要的指导意义和借鉴价值。

On the basis of analysis and comparison of the strata behavior of the fully mechanized slicing mining and sub-level caving workface,it has illustrated the load of props and strata behavior regularity of the Step Soft Seam fully mechanized caving workface by slicing mining and sub-level caving of the Ⅵ 15-17 coal seam of the Thirteen Coal Mine of Pingdingshan Coal Industry Group.The study is of great importance to strengthen controlling of fully mechanized caving mining workface and extending technique of fully mechanized caving mining.
