Abstract:

Groundwater is the main water source producing borehole water gushing in the research area,research shows that groundwater resources are rich in this mine and mainly come from atmospheric precipitation.The development of fault in this mine constitute the gushing water channel,it provide condition for gushing water of main shaft.Through comparative analysis,combined with the shaft geology of the mine,we select hydrostatic throw residue grouting sealing and after-wall grouting cut-off water as the management program of borehole water gushing.Based on this,we describe the construction process,main technical parameters and drainage problems of gushing water management.After the shaft gushing water and submergence,we can block water effectively and complete shaft excavation puzzle by using the methods of build pulp pad and drilling grouting.

Key words: Borehole water gushing, Drilling grouting, Treatment program, Metal mine, Sichuan Province
