摘要
针对不规则工作面在回采过程中的缩面回采难度大、回采效率低等技术难题,分析了不规则工作面传统回采工艺存在的技术问题,提出了"补巷缩面回采工艺"方案,有效提高了工作面缩面回采效率,增加了工作面煤柱回采量,保证了缩面回采期间设备回撤安全。
In view of the technical problems in irregular working face, such as the difficulty of shrinking face mining and low recovery efficiency, the paper analyzes the technical problems existing in the traditional mining technology of irregular working face, and puts forward the scheme of "roadway supplement and face shrinkage mining technology", which effectively improves the recovery efficiency of the working face, increases the coal pillar recovery amount of the working face, and ensures the safety of equipment withdrawal during the mining period of the shrinking face.
