新型前探梁的研制及应用

Development and Application of New Type Cantilever Roof Bor

在煤矿掘进工作时前探梁对于加强顶板管理,防止冒顶事故的发生起着举足轻重的作用,目前前探梁种类很多,但大多数前探梁在设计时多注重了"护",轻视了"支"。千秋矿根据自己的工作条件设计出了与空顶直接接触的前探梁,支护范围可根据实际要求做出调整,实现了对空顶的真正支护。

In mine excavation work before the probe beam for strengthening roof management, prevent roof fall accident play a decisive role, currently in front of many types, but the majority of cantilever beam in the design of pay more attention to ＂support＂, ＂branch of contempt＂. Qianqiu Coal Mine according to the working conditions of their own designs and empty top in direct contact with the cantilever beam, the supporting range can be adjusted according to the actual requirements, the emntv top real support.
