针对六家煤矿东一辅助运输大巷存在严重底鼓的问题,提出了“底板注浆+锚索束+底梁”联合加固技术,并对注浆参数、锚固参数及施工工艺进行了研究。工程实践表明:该技术能够有效控制软岩巷道底鼓,顶底板最终移近量为71~91 mm,巷道表面位移量在12~15 d以后趋于稳定。
針對六傢煤礦東一輔助運輸大巷存在嚴重底鼓的問題,提齣瞭“底闆註漿+錨索束+底樑”聯閤加固技術,併對註漿參數、錨固參數及施工工藝進行瞭研究。工程實踐錶明:該技術能夠有效控製軟巖巷道底鼓,頂底闆最終移近量為71~91 mm,巷道錶麵位移量在12~15 d以後趨于穩定。

Aiming at the serious problems of floor heave in east auxiliary transportation roadway in Liujia coal mine, the joint supporting technique is used to control floor heave by means of field investigation,and the grouting parameters, anchoring parameters and construction technology were studied. The engineering practice shows that the combined support technology is an effective way to control floor heave, and the top and bottom of the final deformation amount is 71~91 mm, and the amount of surface displacement of roadway is stable after 12~15 days latter.
