In order to study the main inluencing factors of the maximum surface subsidence velocity in 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 significance analysis of orthogonal design and factor influence analysis of comprehensive design, the variation rule of maximum subsidence velocity under different working conditions was obtained. The results showed that the factors affecting the maximum subsidence velocity ranked from important to unimportant were mining thickness, propulsion speed, overlying rock robustness coefficient, and mining depth. In deep mining, mining depth was not an important factor of the surface subsidence rate. The maximum subsidence velocity was negatively correlated with overlying rock robustness coefficient, and positively correlated with mining thickness and propulsion speed of working face.
