Study on the Principal of Ground Pressure within the Top Irregularly Damaged Zone in Working Face

Abstract:

Top layered irregular damage zone conditions under stratified due to the stress concentration caused by the upper residual coal will lead to increased recovery difficult. This article by tracking Laokengkou coal mine 7408 face advancing the rock pressure value in the process and analysis, to grasp the distribution of stress concentration in different locations in the process of mining face, for the safety evaluation of the current conditions support improvement measures formulated to provide the necessary reference.
