摘要
针对杨河煤业32071中联巷车场难以支护的问题,从巷道的破坏特征入手,在现场调查的基础上,分析了巷道破坏变形的机理,并利用地质雷达对巷道围岩松动圈进行探测,确定了巷道的破坏深度及耦合支护所用锚索长度。以此为基础,提出棚-索-围岩耦合支护方案,有效控制了巷道的变形,取得了良好的支护效果。
For the problem of difficulty surporting, from the failure characteristic of roadway, and based on the field investigation, analyzed the the mechanism of failure and deformation of the roadway and detectived the loose circle of the surrounding rock by using geological radar, got the failure range of the roadway and the anchor cable length needed. Taking these as the base, the coupling support technology of frame and anchor cable was put forward; the deformation of the roadway was under the control, and the good supporting effect was achieved.
