Application of Controlled Blasting Method in Cutting Pressure Relief Tanks in Shaft Walls
Based on the theoretical analysis of shaft wall fracture,rock mass blasting and controlled blasting,combined with the engineering practice of controlled blasting cutting pressure relief groove in the fracture part of a wind shaft,this paper studies the rapid cutting pressure relief groove of controlled blasting technology in the fracture part of shaft.Through the combination of theory and practice,the controlled blasting technology of"partition blasting,vertical cutting,two-side expansion brush"has been successfully applied to the controlled blasting cutting and pressure relief groove project of shaft rupture wall,and good construction results have been achieved,which provides guiding significance for the controlled blasting cutting and pressure relief groove of relevant mine rupture wall.
