Abstract：For the problem of severe strata pressure of the shallow buried working face pass through the hill in Shendong mining area, research methods of uniform design and numerical simulation are applied to establish the regression model between the increased stress coefficient of shallow-buried face under the hill and the main influence factors. The results show that the increased stress coefficient is proportional to the mining height and the hill height, and inversely proportional to the hill slope angle and the depth of working face; the primary and secondary sequence of the factors sensitivity is mining height, hill slope angle, hill height, and depth of the working face. Compared with mine pressure monitoring values of Huojitu coal mine 12305 working face and Shangwan coal mine 12206 working face pass through the hill and their regression results, the maximum deviation is 4.4% of the monitored value. The strata behavior degree of the shallow buried working face under the hill can be relatively accurately forecasted by the regression equation.
