Study of Mine Pressure Appearing Law for Blasting Mining Face in Steeply Inclined Coal Seam

摘要：

　　On the basis of field observation,mine pressure law and characteristc of single hydraulic prop force were investigated in No.12313 steep mining face of Linsheng mine.It is found that the load increases gradually from the pillars of the first row to the end of pillars,thus,the load of the latest pillars is largest.The pace distance of the main roof periodic pressure is 1/2.45 that of the first weighting step distance by theoretical derivation,and the result is in accordance with field observation.Advancing stress concentration zone beyond the original rock stress exists in the front of mining face wall,and its stress increases with closing to the upper roadway.
