摘要
Through the research of the coal seam conditions in sublevel caving mining technology,height of the fractured zone and mining technology,combined with practical experience,the paper proposed the spacial concept of separation layer,water storage space of fissures and methods for water prevention and control.Use of the comprehensive test confirmed the presence of the separation layer,water storage space of fissures,realized underground drainage.The results show that Luohe Formation sandstone aquifer is the main source of water,mine water inflow has a close relationship with mining technology,separation and water storage space of fissures are unique geological phenomena in modern mining technology.
