摘要

为有效控制623进风道动压明显区域的围岩变形,根据623进风巷道的条件,分析了围岩变化特性,优化了623进风巷道的支护参数,在锚索选型上采用"鸟窝"锚索,有效控制了623进风巷道动压明显区域的围岩变形,保障了矿井采煤工作面的安全高效生产,降低了生产成本。
        In order to effectively control the surrounding rock deformation of 623 intake tunnel with obvious dynamic pressure, according to the conditions of 623 intake tunnel, the variation characteristics of surrounding rock are analyzed,the supporting parameters of 623 intake tunnel are optimized, and the "bird's nest" anchor cable is adopted in the selection of anchor cable, which effectively controls the surrounding rock deformation of 623 intake tunnel with obvious dynamic pressure, ensures the safe and efficient production of coal mining face, and reduces production cost.
