摘　　要：为了解决某矿的破碎带巷道支护问题,针对矿井深部复杂地质条件下巷道支护技术进行了研究,分析了混凝土支护、锚杆支护和锚喷支护三种支护方式力学特征,应用数值模拟技术对支护方式作出比较,通过数值模拟结果,现场实测表明:混凝土支护效果最差,锚喷支护效果最佳。In order to solve the problem of roadway support in the broken zone of a mine,a research was carried out under the complex geological conditions in the deep part of the mine,analysing the mechanical characteristics of three kinds of support methods,namely concrete support,anchor support and anchor spray support,and applying numerical simulation technology to make a comparison of the support methods,and the results of numerical simulation and on--site measurements showed that:the ffect of concrete support is the worst,and the effect of anchor spray support is the best.

关 键 词：破碎带 巷道变形 数值模拟 巷道支护
