J. Cent. South Univ. (2020) 27: 2160-2172 DOI: https://doi.org/10.1007/s11771-020-4438-3 Ground subsidence induced by pillar deterioration in abandoned mine districts LUO Rong(罗容)1, 2, LI Guang-yue... subsides slowly; in the worst scenario, shock bump may be induced by pillar and roof collapse. Key words: subsidence; deteriorating pillar; failure process; roof cutting Cite this article as: LUO Rong......
dominates.Dislocation configurations and distributions of strain induced precipitates inside bainitic ferrite of samples relaxed for different times were distinct. When compared with the austenite model steel,which maintained fcc structure even at room temperature, the strain induced precipitates were not found in the sample without relaxation whereas these were distributed outside dislocations in sample relaxed......

caused by the high noise of froth images and the obvious difference of feature importance in sulfur flotation process, a performance recognition method for sulfur flotation process using fuzzy support vector machine was proposed. With the combination of fuzzy membership and feature information gain, the image feature importance was obtained, and the kernel function of fuzzy support vector machine......
