The application of the non-stop wind technology of the inlet and outlet wells of Shanxi Ningwu Dayun Huasheng Zhuangwang Coal Industry was taken as the research object. According to the ventilation situation of the mine, through the analysis and on-site implementation, the existing inlet shaft and return shaft were replaced, which enabled to meet the mine ventilation requirements, save energy and reduce production costs, not only improve the safety of mine ventilation, but also with economic efficiency. The adjusted ventilation system of the mine realized high production, high efficiency, continuous, orderly, environmentally friendly and low investment.
