沿空留巷技术在煤矿开采中的应用

Application of Gob-side Entry Retaining Technology in Coal Mining

现如今随着我国煤矿综采技术的不断提高,我国矿井的开采深度也在持续加深,沿空留巷技术作为煤炭综采中的重要技术,能够有效提高综采安全性,并有效降低采空区域变形,能够为巷道的后续维护奠定扎实基础。与此同时,沿空留巷技术还可以对煤柱的宽度进行具体控制,能够有效隔离巷道和采空区域,确保后期巷道内不会有污水和有害气体进入。本文将对沿空留巷技术在煤矿综采中的应用进行具体分析,希望可以有效提高我国煤矿的开采效率。

Nowadays,with the continuous improvement of fully mechanized mining technology in China’s coal mines,the mining depth of China’s coal mines is also deepening.As an important technology in fully mechanized coal mining,gob-side entry retaining technology can effectively improve the safety of fully mechanized mining and effectively reduce the deformation of goaf,which can lay a solid foundation for the subsequent maintenance of roadway.At the same time,the gob-side entry retaining technology can also control the width of coal pillar,which can effectively isolate the roadway and goaf,and ensure that no sewage and harmful gas will enter the back roadway.This paper will analyze the application of gob-side entry retaining technology in fully mechanized coal mining,hoping to effectively improve the mining efficiency of coal mines in China.
