摘　　要：为了对不同顶板岩性的巷道支护参数进行设计研究,研究了Ⅰ、Ⅱ、Ⅲ级顶板的巷道支护参数,分析了工程类比法、松动圈测试法、理论计算法、数值模拟法等支护参数设计方法的特点,结合某煤矿矿区的具体条件,选择数值模拟法对不同顶板岩性的巷道支护参数下进行设计研究,模拟分析了不同级顶板巷道围岩的塑性范围分布和围岩周边应力分布。最后设计研究了各级顶板的巷道支护断面。研究为类似工程条件的巷道设计提供了借鉴。In order to design and study the supporting parameters of roadways with different roof lithology,the supporting parameters of roadways with grade I,II and III roofs are studied,the characteristics of supporting parameters design methods such as engineering analogy method,loosening circle test method,theoretical calculation method and numerical simulation method are analyzed,combined with the specific conditions of a coal mine,the supporting parameters of roadways with different roof lithology are selected by numerical simulation method,the plastic range distribution and stress distribution around the surrounding rock of different roof roadways are simulated and analyzed.Finally,the roadway support section of all levels of roof is designed and studied.The study provides a reference for roadway design under similar engineering conditions.
