摘要
62711工作面是杜儿坪矿北七盘区首采工作面,为提高回采率及缓解生产衔接问题,推广应用了"切顶卸压沿空自动成巷工艺",并在此过程中对工作面、巷道矿压规律进行了相关研究,现该巷道已成功留设1 500 m,该巷道的成功留设为指导矿井生产提供可靠依据。
62711 working face was the first mining face Northern No.7 of the Du’erping Mine. In order to improve the recovery rate and ease the production connection problem, the "automatic road-forming process along the top of the roof was applied."In this process, the related research of the mining pressure of the working face and roadway were carried out,The roadway was successfully completed with the remaining 1 500 m.providing a reliable basis for the mine production.
