摘要
沿空留巷可以提高采出比、降低巷道掘进量、降低瓦斯灾害。文中探讨了煤矿开采中围岩稳定性的影响因素,认真探讨了沿空留巷顶板在破断时的原理过程,为沿空留巷技术的在煤矿中的合理使用提供了非常重要的参考作用。
Gob side entry retaining can improve the recovery ratio, reduce the amount of roadway excavation and reduce the gas disaster. This paper discusses the influence factors of surrounding rock stability in coal mining, The principle and process of roof breaking in gob side entry retaining are discussed, it provides a very important reference for the reasonable use of gob side entry retaining technology in coal mine.
