高应力强流变软岩巷道底臌防治技术研究应用

Research and Application of Prevention of Heave on Intensive Rheological Soft Rock Roadway Under High Stress

针对华亭煤矿高应力松软岩巷道底臌变形破坏情况及岩性特点,研究采用高强度锚网索、钢筋混凝土、底板锚注全断面支护技术,进行软岩巷道底臌防治,解决支护问题。该技术经过2年多的研究应用,取得了显著成效。

According to the damage floor heave and rock chracteristics of soft rock roadway under high stress in Huating Coal Mine, whole section supporting techonogy with high strengh cable anchor, reinforced concrete and floor bolt - grouting is researched and used to prevent floor heave in soft rock roadway and solve the supproting problem. After the application during two years, this supporting teconology has made a great success.
