Abstract
Development of mining subsidence in the coal mining area is impacted by the geological occurrence conditions and mining design conditions. Therefore, taking the Yushenfu coal mining area in northern Shaanxi province as study area, the research analyzed the key geological and mining impact factors of the mining subsidence respectively with grey correlation analysis method and stepwise regression analysis method. The results show that the perturbation coefficient, synthetical protodyakonov coefficient of overburden rocks, width-depth ratio and the ratio of mining depth and height are selected as the key geological-mining factors impacting mining subsidence in YuShenFu coal mining area. It hopes that the research results can present the scientific guiding function for the prevention of mining subsidence in the future.
