在巷道支护参数优化设计中,将模糊数学和可拓学相结合,建立起巷道支护效果模糊可拓综合评价模型,分别从技术层面和经济层面进行分析,为最优支护方案的选择提供数据依据。为确保巷道的安全性,应用锚固复合承载体稳定性判据对最优方案进行验证。将此优化方法应用到古城矿回采巷道支护参数优化中,结果表明优化方案既能保证巷道围岩控制效果,又能提高巷道掘进速度,减少支护成本。 In the optimal design of roadway support parameters, fuzzy mathematics and extenics are combined to establish a fuzzy extension comprehensive evaluation model of roadway supporting effect, which is analyzed from the technical level and the economic level separately, which is the choice of the optimal support plan Provide data basis. In order to ensure the safety of roadway, the optimal scheme was verified by applying the stability criterion of anchored composite carrier. The optimization method is applied to the optimization of support parameters for the mining roadway in Gucheng Mine. The results show that the optimization scheme can not only ensure the surrounding rock control effect, but also improve the tunneling speed and reduce the support cost.
