| 摘 要： | 根据煤巷锚杆支护参数设计中存在的问题,结合榆家梁矿的巷道布置具体情况,通过理论分析和现场试验,提出了适合煤巷特点的锚杆合理支护参数设计方法,即"地质力学评估—数值模拟—初始设计—现场观测—修改设计"的设计方法。现场实际测得松动圈范围,分析了巷道围岩情况及其松动圈规律,通过理论分析和现场试验,设计了合理的巷道锚杆支护参数,经过现场试验分析,锚杆有效的控制了巷道的变形破坏。取得了较好的应用效果。

| Abstract: | This thesis based on the problem that existence in supporting parameter design of bolt in coal tunnel. Through theoretical analysis and field experiment associate with the condition of Yujialiang coal mine. We find out a new appropriate supporting parameter design method of bolt that appliance to the coal tunnels of Yujialiang coal mine, as the design method of ＂geomechan- ics assessment -numerical simulation-initial design-field observation--revise design＂. We measured loose ring of surrounding rock of roadway. , Through theoretical analysis and test analysis the loose circle of law. We design reasonable roadway bolting support parameters, through the analysis of field test of bolt, effective control of the tunnel distortion. Good results have been achieved. |
