摘要
为了解决巷道顶板不稳定的条件下单轨吊悬吊问题,针对具体的顶板情况,探讨了悬吊结构中锚索、锚杆受力状况,分析了锚索、锚杆联合悬吊技术的可行性。在阳煤集团开元矿9~#煤七采区工作面巷道顶板进行工程实践,结果表明,悬吊结构对巷道变形和稳定影响极小,该技术可进一步推广使用。
In order to solve the monorail suspended problems under the condition of unstable roadway roof,based on an analysis of condition of the concrete roof,the paper discusses the condition of the suspension structure of anchor cable,anchor stress,analyzes the feasibility of anchor cable,anchor combined suspension technology.The practice in the working face of N0.7 mining area,Kaiyuan 9#mine,Yangquan Coal Mine Group,shows that the suspended structure has little impact on the deformation and stability of roadway,so the technology can be used further.
