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。
Coal mining face, the lower end is directly linked with the upper and lower sections of roadway, and were arranged scraper conveyor head and tail, and more mechanical and electrical equipment, frequent personnel, require a larger work space, by the tunnel And mining face mining pressure greater impact, roof activity, is a frequent site accidents. End support situation directly affects the rapid promotion of mining face and safety production, in order to ensure safe and efficient mining, end bracket design and research of great significance.
