摘　　要：介绍了由于地质条件复杂 ,受构造和机械化开采等因素影响导致的走向较短的边角块段 ,阐述了采用双面联采 ,减少了区段平巷 ,从而降低万吨掘进率 ,缓解采掘接替紧张矛盾 ,减少煤柱损失 。Because of complex geology condition,the factors of structure and mechanized mining,produce short side angle and section in direction,but adopt double face combined mining can reduce section roadway,decrease ten thousand ten drivage ratio,losse mining replacement serious, reduce coal pillar loss so as to realize stable and high production at face.
