| Abstract: | Based on the observations of the rock pressure and its changes during the period from initial mining and finishing mining in north-north #4 blast mining coal face at 20 level in Chang'gouyu Coal Mine plus the characteristics of strata pressure behaviours,this article determines the first roof weighting intervals and the periodic weighting intervals at the face.In this way,the regularity of roof movement during mining process is mastered.This provides sound grounds for roof management for mining in #4 coal seam. |
| Keywords: | inclined coal seam blast-mining wall-face mine pressure regularity |
