U型钢撑式梁在综采面运输巷超前支护中的应用

Application of U-shaped Steel-supporting Beams in Advanced Supporting of Headgate on Fully-mechanized Working Face

为了更加科学地对综采工作面运输巷道进行超前支护,对平煤股份四矿戊9.10-19150综采面开采过程中的运输巷道侧压进行了分析,提出了用U型钢撑式梁控制侧压增加的方法。实践表明:U型钢撑式梁能够有效平衡拱形巷道周围的矿山压力,确保了设备及通风、行人的安全。

To support headgate in advance more scientifically on fully-mechanized working face,the paper analysed the side pressure of headgate in the process of mining on Ⅵ9.10-19150 fully-mechanized working face in Pingdingshan No.4 Coal Mine.The method of using U-shaped steel-supporting beams to control side pressure was proposed in the paper.Practices shows that,U-shaped steel-supporting beams can effectively balance the surrounding rock pressure of arched roadway,and can ensure the safety of equipment,ventilation and pedestrian.
