南屯矿实现复杂条件下放顶煤开采最近，兖州矿业集团南屯煤矿成功地进行了在复杂条件下的放顶煤开采。该项目首创将超前预报与应用技术相结合，解决了国内首例巷道顶煤自燃的问题。这项课题是在缓倾斜厚煤层俯斜及有煤层自燃瓦斯聚集严重倾向的“孤岛”面综放开采条件下进... Recently, the top coal caving has been carried out under complicated conditions in Nantun Mine Recently, the Nantun Coal Mine of Yanzhou Mining Group has successfully carried out the caving mining under complicated conditions. The project pioneered the combination of advanced forecasting and application technologies to solve the problem of top coal spontaneous combustion in the first domestic roadway. This project is under the condition of fully mechanized caving in “island” face where the inclination of thick inclined coal seam and the spontaneous combustion of gas with spontaneous combustion of coal seam are serious.
