Water prevention and control technology with grouting for base rock section of East ventilation shaft in Qidong Mine

WU Jun-song,Xu Bing-feng(New Mine Preparation Office of Qidong Mine,Wanbei Coal and Electric Power Group Corporation Ltd.,Suzhou 234100,China)  
The base rock section of East Ventilation Shaft in Qidong Mine passed through 2 medium particle sandstone aquifers.The first aquifer was in the section of the ground freezing area and the second aquifer would be sunk through with the pregrounting at the face.With the higher quality concrete for the grouting cover,the rational drilling program and the grouting density,the higher grouting pressure,the adjustment of grouting section height and other measures,the grouting operation period was reduced and the grouting results was ensured.
