摘要
During the construction of drilling hole for groundwater in Qingyang District,water burst accident always happened below 1060m above sea level because this position is abnormally rich in groundwater.Through analysis of the hydrogeological conditions in the work area,this paper put forward the solutions of water burst accident,such as the balance method of formation pressure,stoping gushing with sealer,water separation with water insulation casing,drilling while water gushing and so on.
