Abstract：In order to solve many design problems such as deep burial of coal seams,coexistence of oil,gas and coal,poor lithology and water content of Cretaceous strata causing difficulty in shaft construction,high ground pressure,high risk in coal seam spontaneous combustion,and ecological fragility and environmental pressure in Shila Wusu Coal Mine,multiple technical and economic comparisons,optimal industrial site location and shaft layout,innovative wellbore freezing technology,optimal first mining area,establishment of reliable disaster prevention system,zero discharge of gangue and other design concepts and methods were adopted.According to the construction and production verification,after taking corresponding measures,it is feasible to develop and construct a modern extra-large mine that is intelligent,information-based,green and safe.This design result can provide reference for the design and construction of similar mines.
