Abstract

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.
