摘要
采煤工作面上、下端头是直接与上、下区段巷道相联,而且分别布置刮板输送机头和机尾,机电设备多,人员出入频繁,要求有较大的工作空间,受巷道和工作面采动矿压的影响较大,顶板活动强烈,是工作面事故多发地点。端头支护情况直接影响回采工作面的快速推进和安全生产,为保证安全高效开采,端头支架设计研究意义重大。
The mining work surface,the bottom head is directly related to the upper and lower section of the associated roadway,and are arranged scraper conveyor head and tail,electrical and mechanical equipment and more personnel access frequently,requiring a large working space,by the roadway and the face in the impact of higher strata,the roof is intensive,is the Face of the accident-prone locations.End support directly affect working face of the rapid progress and safety,to ensure the safe and efficient mining,end support design of great significance.
