| Abstract: | Combining the characteristics of the complex geological structure of the No.3 coal seam in Lanxi Kechuang Yuxi Coal Mine and the indeterminate in-situ stress,the commonly used in-situ stress measurement methods are introduced,and the stress relief method is used to measure the in-situ stress of the 3#coal seam.As a result,the coal pillars in the mining roadway of the 3#coal seam,the coal(rock)pillars of the roadway protection roadway,and the coal pillars of the stop line have been reserved,which ensures the mining safety of the 3#coal seam in Yuxi Coal Mine. |
