3_(下)7115综放工作面大倾角回采工艺研究与应用

Research and Application of Large Dip Angle Mining Technology in the 3_(lower) 7115 Fully Mechanized Top Coal Caving Face

针对田陈煤矿3_(下)7115综放工作面大倾角回采,采取控制采高、调整液压支架架型、加强设备检修等措施,有效管控顶板,实现运输机与转载机搭接合理,保障了工作面安全有序推采。

Aiming at the large dip angle mining of the 3lower 7115 fully mechanized caving face in Tianchen Coal Mine,measures such as controlling the mining height,adjusting the hydraulic support frame type and strengthening the equipment maintenance are adopted to effectively control the roof,so as to realize the reasonable overlap between the conveyor and the transfer machine,and ensure the safe and orderly push mining of the working face.
