摘要
通过数值模拟方法,研究了煤巷锚杆支护效果,分析了地应力、围岩强度、围岩结构、巷道断面对锚杆支护效果的影响,对锚杆支护设计提供借鉴。
By numerical simulation, the paper studies the bolt support effect and analyzes the influence caused by ground stress, surrounding rock strength and structure, and cross-section of roadway, which can be useful for bolt support designs.
