A kind of surface mine explosion shifts measuring method

The invention discloses a kind of surface mine explosion to shift measuring method, placed in multiple-row blasting section or blasthole periphery add drilling and fill dyestuff or paint while fill the vial of pressurized inert gas, the lower vial of blast pressure effect crushes, inert gas bleeds off pressure instantaneous expansion, dyestuff colours periphery ore-rock under inert gas driving, the ore-rock being colored will move with step main body along instantaneous scope of freedom direction, the coordinate data of quick-fried preceding drilling and quick-fried poststaining ore-rock is obtained using high-precision GPS alignment system, contrast it is quick-fried before, coordinate carries out explosion displacement measurement after quick-fried and the displacement of ore-rock line of demarcation determines.The monitoring and visualization of explosion displacement are the method achieve, ore area distribution, improves the ore resource rate of recovery and mine economic profit after accurate identification is quick-fried, has an important theory and practice meaning to the exploitation of surface mine ore-rock.
