摘要
随着煤层采深的不断增加,受上覆岩层压力作用也越来越大。沿空留巷技术作为一种新型巷道支护手段对于提升煤炭开采率有着积极影响。对综采工作面沿空留巷顶板支护进行探究,为其它工作面的开采工艺提供借鉴。
With the increasing of coal mining depth, the overburden pressure is also growing. As a new means of roadway, roof supporting of the laneway along the gob has a positive impact on enhancing the rate of coal mining. Roof supporting of the laneway along the gob on mechanized mining face was studied, which provide a reference for mining technology on other face.
