Abstract:deep mining, a surface subsidence analysis model of mining depth, mining thickness, overlying rockfirmness coefficient and propulsion speed in deep mining was established. Based on the factor signifi⁃cance analysis of orthogonal design and factor influence analysis of comprehensive design, the variationrule of maximum subsidence velocity under different working conditions was obtained. The resultsshowed that the factors affecting the maximum subsidence velocity ranked from important to unimportantwere mining thickness, propulsion speed, overlying rock robustness coefficient, and mining depth. Indeep mining, mining depth was not an important factor of the surface subsidence rate. The maximumsubsidence velocity was negatively correlated with overlying rock robustness coefficient, and positivelycorrelated with mining thickness and propulsion speed of working face. Close-
