摘要

Gob-side entry retaining is an advanced and green mining technology,which can avoid using pillar and island working face,reduce driving workload,alleviate the tension between extraction and driving,and achieve a Y-type ventilation.The coal mine in this research successfully reserved a 485m roadway in No.10302 fully mechanized coal face by employing wide lane driving,pre-driven roadway,pre-controlling immediate roof in the roadway,and gob-side entry retaining by walling up with multi-standard concrete block using break-joint vertical stacking technology.From doing so,the supporting effect is significant,the roadway is integrated and the stable wall is free of distortion or cracking.This research paves a new way for gob-side entry retaining of fully mechanized mining in China.
