我矿使用的是苏制 T_(13)K 型插腿式掩护支架,这种型式的上端头支架(后称端头支架),在使用中暴露出一些值得研究和急待解决的问题,这在相类似的综采工作面中有一定的普遍性。一、端头支架处的现状及改善的径途端头支架和风巷上帮之间总是有一段大小不等的距离,溜子机尾一般又比支架向上帮长出一段,这样在端头支架和风巷上帮之间就形成了一条窄长的空隙,这个空隙宽一般在0.5～2m,长一般在4～6m,正处于采面上隅角部位。端头支架的管理对安全生产有着重要的关系。
My mine is using the Soviet-made T_ (13) K-type leg shield type shield, this type of upper end bracket (later known as the end bracket), the use of exposed some worthy of study and urgent problems, which In a similar fully mechanized mining face in a certain degree of universality. First, the end of the stent at the status quo and improve the way End of the bracket and the airway upstairs there is always a range of sizes ranging from the general skateboard tail than the stent to help out a period of growth, so in the end bracket Alley wind and help to form a narrow gap between the gap, the gap width is generally 0.5 ~ 2m, usually 4 ~ 6m long, is located in the corner of the mining area. The management of end brackets has an important relationship with work safety.
