- W3118532930 abstract "Abstract Horizontal concave slope structure is a common mining structure. It is the basis of mining safety to grasp the reasonable mining distance of horizontal concave slope. Therefore, based on variable scale chaotic algorithm, the reasonable mining distance of horizontal concave slope is studied. The safety factor is used to describe the reliability of the slope. When the slope is in a reliable state, it is a reasonable mining distance. Based on the Warehouse–Mohr strength theory, the four key parameters of rock cohesion and internal friction angle of horizontal concave slope and major and minor stress of element nodes are considered. The similarity of mining safety factor of horizontal concave slope is measured and the objective function is constructed. The target is searched based on variable-scale chaotic algorithm. The output result is the optimal solution of reasonable mining distance for horizontal concave slope. The experimental study shows that the reasonable mining distance of horizontal concave slope can be obtained effectively based on variable scale chaotic algorithm, and the slope height and slope angle are inversely proportional to the mining reliability of horizontal concave slope." @default.
