综采工作面切眼联合支护技术探析

Analysis of Combined Support Technology for Cutting Holes in Fully Mechanized Mining Face

开切眼是综采工作面开采的重要环节之一,特别是随着煤矿开采深度的不断增加,全面做好综采工作面切眼联合支护对于保证综采安全性有着非常重要的作用.本文以某工程为实际案例.分析了综采工作面开切眼煤柱留设技术要点,重点研究了综采工作面切眼联合支护技术要点,从现场应用情况来看,取得了较好的联合支护效果,对类似综采工作面切眼联合支护有一定的借鉴意义.

Open-cut is one of the important links in fully mechanized mining face.Especially with the continuous increase of mining depth in coal mine,it is very important for fully mechanized mining face to fully complete the combined support of open-cut to ensure the safety of fully mechanized mining.This paper takes a project as an actual case.This paper analyzes the technical points of coal pillar retaining in fully mechanized working face,and focuses on the technical points of combined support in fully mechanized working face.From the field application,good combined support effect has been achieved,which has certain reference significance for similar combined support in fully mechanized working face.
