“三软”煤层综放面矿压规律及支架适应性研究

Study on strata pressure laws and adaptability of supports in fully mechanized top-coal caving face ofthree-soft seam

通过对陕西秦源煤矿N101综放面实际观测数据进行分析,得出了“三软”复杂结构煤层综放面矿压显现活动规律,并对支架的适应性进行分析。

In this paper, by analyzing ground behavior measure data from the working face N101 in Qinyuan coal mine ,strata pressure laws of fully mechanized top-coal caving face in three-soft seam are discussed. Moreover, adaptability of the powered support is analyzed, which offers scientific basis for support design at similar conditions.
