摘要
铜川矿务局鸭口煤矿2220综采工作面顶板为典型的复合顶板,地质条件复杂。巷道布置时受煤层厚度和巷道使用高度的影响,存在层位选择的问题。通过UDEC数值模拟软件分析与现场实践相结合,合理确定巷道层位,采用高强锚网索支护得到了良好的效果。
Because the roof of 2220 mining face is a typical compound roof,the roadway layout is influenced by seam thickness and roadway height.The paper determined the rational horizon of roadway and support with bolt,net and cable based on UDEC numerical simulation and field practice.
