东海煤矿是龙煤集团典型深部开采矿井,矿井在深部开采过程中,出现回采巷道变形严重、采场矿压显现剧烈、瓦斯涌出量增大、深部煤岩层温度不断升高等灾害,致使作业环境不断恶化。以下分析了东海矿六采区34#上左六采煤工作面近距离煤层采场上覆岩层运动及矿压显现规律,对煤矿安全高效开采具有一定指导意义。
The Donghai coal mine is a typical deep mining mine of Longmeng Group. During the deep mining process, the serious deformation of the mining roadway, dramatic occurrence of mine pressure in the stope, increase of gas emission, rising of temperature of deep coal rock formation, Deteriorating. The following is an analysis of the law of overlying strata movement and the occurrence of overburden strata in the close-seam coal seam in the left-6th coal mining face of the No. 6 coal seam in the No.6 mining area of Donghai Mine, which is of guiding significance to the safe and efficient mining in coal mines.
