摘要
随着煤矿开采深度的加大,以往可获得良好支护效果的传统支护方法,在诸多条件下已出现显著的支护不协调、支护强度低等问题.在进行沿空留巷支护时,出现了与上述类似的问题,给整个综采工作面的正常开采带来了很大的困难.主要介绍了当前综采工作面沿空留巷支护技术应用存在的问题及原因,重点分析了综采工作面沿空留巷的巷旁支护技术和巷内支护技术.
Abstract
With the increasing depth of coal mining,traditional support methods that used to achieve good support effects have encountered significant problems such as inconsistent support and low support strength under various conditions.Similar problems as mentioned above occurred during the support for gob-side entry retaining,which posed great difficulties to the normal mining of the entire fully mechanized mining face.This paper mainly introduced the problems and reasons of the current application of support technology for gob-side entry retaining in fully mechanized mining face,with a focus on analyzing the roadside support technology and roadway support technology for gob-side entry retaining in fully mechanized mining face.
