采矿巷道设计效率的研究

Research on the Design Efficiency of the Mining Roadway

采用层次分析法建立一种评价煤矿巷道设计效率的方法,阐述了自然因素、地质力学因素、采矿和技术因素对巷道稳定性的影响。对巷道设计和维护影响最大的因素有构造扰动、地震活动、岩体节理和抗压强度、附近开采巷道和支护承载能力。根据层次分析法的结果,对各影响因素对巷道支护设计及其稳定性的影响进行了百分比评价。根据所列指标,可以规划修改后的承载力支护方案。

A method to evaluate the design efficiency of coal mine roadway is established with the influence of natural factors,geomechanics,and mining and technical factors on roadway stability.The biggest factors on the design and maintenance of roadway are structural disturbance,seismic activity,rock joints and compressive strength,nearby mining roadway and support bearing capacity.According to the results of hierarchical analysis method,the influence of the influencing factors on roadway support design and stability was evaluated.According to the listed indicators,the revised bearing capacity support plan can be planned.During the excavation or use phase,this method will prove to be useful in calculating the necessary reinforcement.
