摘要:
摘要:为提高煤炭资源采出率、减少巷道掘进量、缓解采掘接替紧张局面,部分煤矿采用沿空留巷技术对工作面顺槽进行维护。在复合顶板条件下,采用何种支护方式对工作面顺槽顶板进行有效控制是保证综采工作面沿空留巷成功的关键。

Abstract: in order to improve the recovery rate of coal resources, reduce the amount of roadway excavation, alleviate the mining-excavation tensions, part of the mine using gob-side entry retaining technology to face crossheading maintenance. In the condition of composite roof, which support on working face roof control is to ensure the effective channel for fully mechanized coal mining face roadway along goaf the key to success。
