FIELD: blasting operations. ^ SUBSTANCE: method is suggested of loading well with explosives on the basis of granulated ammonia nitrate, which includes supply of explosive into well with simultaneous thermal treatment of explosive. Thermal treatment is carried out with sensitising additive with temperature of 50 - 80C, which consists of spent gases of internal combustion engine and vapour and drops of oxidiser water solution and fuel. As oxidiser ammonia and/or sodium nitrate are used, and as fuel - carbamide and/or glycol, and/or hexamethylenetetramine. ^ EFFECT: increase of blasting operations efficiency at the account of density increase; increase of detonation characteristics; uniformity and stability of component composition of explosive at height of charge column. ^ 3 cl, 1 tbl, 1 dwg, 1 ex |
