S4001工作面放顶煤开采临时支护工艺研究

Study on the Technology of Temporary Support of Mechanized Coal Caving Mining on the Working Face S4001

本文通过介绍砂墩子煤矿优化前及优化后的前探梁临时支护方式,优化后前探梁临时支护,操作方便、快捷、简单,随掘进前移,紧跟迎头,能够及时有效地控制顶板,防止顶板片帮、冒顶事故发生,在保证施工安全的同时,大大提高了工作效率。

This paper introduces the temporary support of the front beam of Shadunzi Coal Mine before and after the optimization to optimize the forestope temporary support. It is easy to operate, fast and simple. With the driving forward, it can head-on follow and timely and effective control the roof to prevent the accidents of roof spalling and roof falling. It can ensure the safety of construction and greatly improve the efficiency.
