Research on geological security technology for safe mining under high-intensity mining conditions
In order to solve the problem of mine water inflow and surface ecological problems in Xiaobaodang No.1 Coal Mine,the prediction of mine water inflow and the height of fracture development were studied by theoretical analysis and field measurement.The research showed that the mine water inflow of Xiaobaodang No.1 Coal Mine was increasing as a whole,and it was related to surface precipitation,working face mining range and production capacity.According to the theoretical calculation,the maximum water inflow of the mine was 875 m3/h,and the fracture development height was 127.6～162.4 m,which was connected with the goaf of the upper coal seam,and there was a risk of water outburst.In view of the actual situation of the mine,targeted geological safeguard measures were put forward to ensure the safety production of coal mine.
