采煤方法选择及采区布置探讨

On Mining Method Selection and Mining Areas Layout

通过对玉井煤矿采煤方法选择及采区布置探讨,得出:9号煤层采用倾斜长壁综合机械化放顶煤采煤方法,全部垮落法管理顶板;本井田9号煤层顶煤冒放性较好,适合采用放顶煤开采;井下9号煤层布置一个综采放顶煤工作面。

The discussion on mining method selection and mining area layout in Yutian Mina drew conclusions as follows. Inclined long-wall fully-mechanized top-coal caving could be adopted in No.9 coal seam with whole-caving method managing roof. With good falling ability, the No.9 coal seam is suitable to use the top-coal caving. Therefore, a fully-mechanized top-coal caving face was set on the seam.
