| Abstract: | On the basis of investigations into the hydrogeology of fissured and karst fissured aquifers,and in accordance with the principles of underwater explosion,presentation is given of the techniques of explosion energy controlling and in hole blasting,which help to fracture the rock body and thereby scour and unblock the fissures so that dredging and draining can be improved without holewalls being damaged. |
