本文从巷道受力角度出发,利用模糊数学方法和国外新近提出的应力和均匀化理论,在巷道断面形状的优化比较方面,首次提出一种根据巷道周围平均应力集中系数MSCF来选择最佳断面形状的定量方法——模糊决策方法。应用此方法,作者结合某矿山深部地质、应力条件,确定该矿深部开采巷道的最佳形状为准椭圆形,为矿山深部开采设计提出了建议。 In this paper, from the perspective of roadway stress, using fuzzy mathematics method and the recently proposed stress and homogenization theory, an optimal cross-section shape is selected for the first time based on the average stress concentration factor MSCF around the roadway in terms of optimization of cross-section shape comparison. The quantitative method - fuzzy decision-making method. Applying this method, the author combines the deep geology and stress conditions of a mine to determine that the best shape of the deep mining roadway in the mine is quasi-elliptical, providing suggestions for deep mining design.
