由于受地质条件的影响,边角煤回收的综采工作面往往无法被布置成等长工作面,并且受已回采工作面的限制,新工作面推进长度也较短,不规则的小工作面布置掘采比高,系统复杂,安拆次数多,不利于安全生产。所以对于边角煤回收工作面的布置,经过详细的方案对比,在条件允许的情况下,将走向与倾向工作面联合布置成一个工作面,采用走向长壁和倾斜长壁相互转换的采煤方法,对于提高矿井资源回收率,延长矿井服务年限具有重要意义。
Due to the influence of geological conditions, the fully mechanized mining face recovered from the corner coal can not always be arranged as an equi-long working face and is limited by the working face that has been recovered. The new working face has a shorter length and an irregular small working face Dredge layout than the high, complex systems, the number of demolition, is not conducive to safety in production. Therefore, for the arrangement of the corner coal recovery working face, after a detailed plan comparison, under the condition that the conditions permit, the coal face moving towards and inclined working face will be arranged as a working face, adopting the conversion of coal to longwall and inclined longwall, Methods for improving the recovery rate of mine resources, extending the service life of the mine is of great significance.
