扇形回采在综采工作面斜长变化中的应用

Application of Sector Circul Excavate to the Change of Oblique in Integrated Excavated Working Face

综采工作面安装、拆除不仅工作量大 ,而且安全风险大 ;扇形回采工艺在综采工作面的应用使综采的适应性增长 ,增加了煤炭资源的回收率 ,减少了综采工作面的拆除、安装次数 ,降低了矿井生产成本 ,为矿井正常接替赢得了主动 ,取得了较好地经济和安全效益。

The installation and backout of the integrated excavated working face has not only much workload, but also a lot of dangers. Now the technique of sector circul excavate is widely used in integrated excavated working face, as a result, the adaptability increases, the rate of coal callback goes up, the installation and backout times of the integrated excavated working face decrease, and productive coat is reduced.
