摘　　要：采煤工作面回采方法很多,根据不同煤层赋存条件制定不同的开采方法,煤层厚度决定煤炭回采的工艺,根据煤厚变化调整采煤方法是切实可行的办法。九龙矿2号煤因地质影响局部煤层分叉,分为2号煤和2号下层煤2层,2号煤厚度为2.6 m,2号下层煤厚度为3.2 m。在施工过程中结合回采工艺及煤炭回收各方面的考虑,在15245S工作面前期使用综采工艺,后期增加后部输送机改为综放工艺。通过对15245S工作面超前谋划,科学组织探索回采过程中工艺的改变,同时摸索出回采期间快速安装后部输送机的方法。mining methods are formulated according to the occurrence conditions of different coal seams.The thickness of the coal seam determines the coal mining technology.Adjusting the mining method according to the change of coal thickness is a practical method.The 2#coal of Jiulong Mine is divided into two layers of 2#coal and 2#lower coal layer due to geological influence.The thickness of 2#coal is 2.6m and the thickness of 2#lower coal is 3.2m.In the construction process,considering all aspects of the mining technology and coal recovery,the fully mechanized mining technology is used in the front of 15245S work,and the rear conveyor is added to the fully mechanized caving technology in the later period.Through advanced planning of the 15245S working face,scientifically organized exploration of technological changes during the stoping process,and at the same time explored the method of quickly installing the rear conveyor during the stoping period.
