METHOD FOR CLEANING-UP OF ORE BED RESERVOIRS BENEATH OPEN PIT BOTTOM

摘要

FIELD: mining.;SUBSTANCE: method for cleaning-up of ore bed reservoirs is performed by means of desalination. In this respect, hole-drilling of solid ore is performed, as well as its explosive rupture, filling of blasted capacity with working solution and egress of product solution. Besides, the outer configuration of blasted capacity is drilled around at an angle equal to slope angle of working ledge. Along the centre line of blasted capacity all the way down the cleaning-up of ore bed an efficient well is drilled. The rest of ore body is drilled around by closed parallel rows of vertical wells. While stable roach is being blasted, all the capacity of blasted ore bed, including its outside configuration, is drilled around by vertical wells of the similar depth.;EFFECT: ensuring stability of open pit side and rising safety level of mining operations.;3 dwg
