锚网联合支护技术在综放工作面拉架巷的应用

Application of Anchor Combined Support Technology in Fully Mechanized Caving Face

结合综放工作面末采筑拉架巷在阳煤一矿的实践与应用,介绍了该支护方式的工艺及效果,并从拆除时间、工程成本、安全系数、劳动强度等方面将锚网支护方式与传统木梁支护方式进行了对比。对比结果表明,采用锚索(网)施工的拉架巷有效地控制了巷道顶板与煤帮的变形与破坏,减少了拉架巷维修次数,降低了工人劳动强度,锚网联合支护技术最终成为阳煤一矿拉架巷的主要方式。

Combined with the practice and application of fully mechanized caving face mining roadway in building up at the end of Yangquan coal mine, introduces the supporting technology and effect, and from the time of removal,engineering cost, safety factor, labor intensity compared with the traditional way of bolting support beams supporting method. The comparison results show that the anchor（Network） construction of the Xiang Lycra can effectively control the deformation and failure of roadway roof and coal, reducing the lane Lycra maintenance times, reducing the labor intensity of workers, anchor combined support technology has become a major coal mine up the tunnel.
