The application of curtain grouting by guide water technology

In this paper, Combine the hydrology geological material and mine gush condition of Dongrong No.1 colliery, analyse the causes of gush, research and advance the curtain grouting by guide water technology. Apply this technology bring the 3s main gush point of Dongrong No.1 colliery, bring about a distinct effect, reduce mine sum gush near to 240m³/h, guaranteed this mine regular progress of build process.
