摘　　要：研究的目的是提高煤矿井巷支护的安全性和效率。一方面,通过实地调研,对煤矿井巷支护过程中的关键参数进行了收集和整理。这些关键参数包括岩层厚度、岩性、围岩应力、支护方式等。通过对这些参数进行分析,确定了对井巷支护影响最大的几个关键参数。另一方面,利用数值模拟方法,针对不同关键参数对井巷支护的影响进行了模拟研究。通过改变关键参数的数值,观察井巷支护的变化趋势,得出了一些定性和定量的结论。实验结果表明,根据确定的关键参数来选择支护方式和参数组合,可以有效提高井巷的支护效果。The purpose of the research was to improve the safety and efficiency of coal mine roadway support.On the one hand,through field research,key parameters in the coal mine roadway support process were collected and organized.These key parameters included rock thickness,lithology,surrounding rock stress,support method,etc.By analyzing these parameters,several key parameters that had the greatest impact on roadway support were identified.On the other hand,numerical simulation methods were used to study the impact of different key parameters on roadway support.By changing the values of key parameters,the trend of changes in roadway support was observed,and some qualitative and quantitative conclusions were drawn.The experimental results showed that selecting the support method and parameter combination based on the determined key parameters can effectively improve the support effect of the roadway.
