滑动构造顶板下综采放顶煤关键技术实践

Practices on Key Technology of Fully Mechanized Top Coal Caving Mining under Sliding Structure Roof

郑州煤电公司告成煤矿工作面煤层极松软,在工作面推进过程中,煤壁片帮极其严重,顶板极易冒落,工作面巷道压力大;工作面煤层底板起伏大,割碴现象普遍,工作面设备磨损严重,同时经常造成工作面运输机压死,给安全生产造成不利因素。通过采取一系列措施,使得告成矿滑动构造下综采工作面实现顺利回采,取得了一定的经济效益。

The seam of the coal mining face in Gaocheng Mine of Zhengzhou Coal and Electric Power Corporation was very soft. During the forward advancing process of the coal mining face, the coal spalling from the coal wall were serious, the roof in the coal mining face were easy to fall down and the gateway pressure of the coal mining face was high. The floor of the coal mining face was rise and fall, the floor cutting phenomenon occurred often and the face equipment was worn off seriously. Meanwhile the face scraper conveyor was often jammed and could cause unfavorable factors to the safety production. With a series measures conducted, the fully mechanized coal mining face under the sliding structure condition in Gaocheng Mine had a successful mining with certain economic benefits.
