大断面回采巷道支护优化研究

Research on the optimization of supporting scheme for large section mining roadway

通过对黄陵二号煤矿207运输顺槽支护参数优化,将207运输顺槽原顶部锚杆锚索支护在同一根钢带上的布置方式变为锚杆锚索交替支护。现场实测表明,优化支护参数后,巷道顶板下沉控制较好,取得较好的应用效果,为二号煤矿引进、开发成套快速掘进设备,发挥机械化、自动化优势奠定了基础。

Based on the present situation of No. 207 transport roadway supporting in Huangling No. 2 coal mine,the optimization scheme that the cable support on the same steel strip was changed into alternate bolt and cable support was proposed. The field measurement shows that the roof supporting effect of roadway is better after optimizing the support parameters, and the application results are better,which lays the foundation for the construction of mechanized and automated mine.
