【摘要】 随着煤矿开采深度的加深和巷道断面的增大,矿压显现程度也在不断加剧,这对巷道支护提出了更高的要求,而支护参数设计是巷道支护设计实现定量决策的关键所在。主要通过分析几种常见的锚杆支护理论的原理并总结相应的计算方法,结合建新煤矿现在的地质环境,设计出不同的锚杆支护参数,根据该矿的地质环境和现在使用的锚杆支护参数,利用数值模拟的方法优化选择出合适的锚杆支护参数。为该矿在设计锚杆支护参数时提供理论基础。更多还原

【Abstract】 Along with the coal mining depth’s deepening and tunnel cross section’s enlargement,the appearance degree of underground pressure also unceasingly to intensify,it sets a higher request to the roadway support,but the parameter design of roadway support is the key to realizes the quota decision-making of roadway support design.This article mainly through analyzes the principle of several kind of common bolting supporting theory and summarizes the corresponding computational method,combined with geological environment of jianxin coal mine,designs the different bolting supporting parameters,according to geological environment of jianxin coal mine and the parameter design of roadway support which is used now,chooses the appropriate roadway support parameter using numerical simulation’s method optimization.,provides the rationale for designing roadway support parameter of Jianxin coal mine.更多还原
