摘要
为了解决玉溪矿巷道底鼓现象,通过深入研究与分析比较,提出了软岩巷道底鼓综合治理技术,即:采用"预应力全长注浆锚索锚固+钢筋笼+‘几’字型钢筋梯子梁+混凝土浇筑"的联合底鼓治理技术。通过现场工程实践表明,该底鼓修复技术在软岩巷道底鼓治理方面起到了很好的效果。
In order to control the roadway floor heaving in Yuxi Coal Mine,the comprehensive control technology for soft rock roadway floor heaving is proposed through deep research,analysis and comparison,using a combined floor heaving control technology comprising pre-stressed full length grouting anchor cable,rebar cage,rebar ladder girder and concrete pouring. According to the results of field engineering practice,favorable floor heaving control effect has been achieved using the proposed technology.
