切顶卸压无煤柱开采技术在综采工作面的应用

Application of non-pillar mining technology with roof cutting and unloading in fully mechanized coal face

以1200工作面开采为研究对象,采用切顶卸压自动成巷新技术,由于卸压断顶可以超前施工,解决了主要工序不能平行作业的问题,能够实现工作面的连续高效回采,工艺简单,有效降低了劳动强度,相比传统充填留巷方法,降低了留巷成本,降低返修率,实现低成本开采,对具有类似地质条件的工作面提供了借鉴。

To mining of 1200 working face as the research object, using the new technology of top pressure relief automatically into a lane, broken roof can advance the construction of unloading due to solved the problem of the main process can＇t parallel operation, can realize the continuous high efficiency mining working face, simple technology, effectively reduces the labor intensity, compared with the traditional method for filling, the left lane to reduce costs, reduce the repair rate, to implement low cost production, is used for reference in similar geological condition of working face.
