济二煤矿113_下 03综放工作面安全高效扇形旋转开采技术

Safety Effective Scalloped and Rotating Exploration of No.113_(lower) 03 Mining Plane in JI er Coal Mine

摘要:

针对在特殊地质条件下和不规则回采综采放顶煤工作面,工作面切眼采取扇形布置能够回收三角区域煤炭资源,从而提高煤炭资源回收率。通过改革现场设备安装,解决了前后部运输机和转载机的搭接问题,获得了开采过程中的几个关键数据,从而保证了扇形区段的安全回采,可有效地提高资源利用水平。

Abstract:

If mining coal in special geological condition and irregular heading stope, by using scalloped arrangement, coal resource in triangle areas can be reclaimed and extraction ratio can be promoted as well. Through reforming equipment installation, conncetion between front and back transportation machines and loading machines are soluted, and a few key datas are gained. Thus, safety extraction of scalloped regions are guaranteed, and utilziation level of coal resource can be promoted as well.
