GRANULAR EXPLOSIVE MATERIAL (MODIFICATIONS)

摘要

The invention relates to blasting operations, in particular, commercial explosive materials used for blasting operations on the surface of opencast collieries, open pits and mines in all climatic zones of Russian Federation and countries - Community of Independent States. The proposed invention is aimed at producing more effective explosive material. To achieve that there proposed a granular explosive material (first modification), representing a granular trinitrotoluene, whose granules have the following disperse composition: more than 1.2 mm - at least 94 mass percent, less than 3.2 mm - at least 85 mass percent, less 5 mm - all 100 mass percent. The granular trinitrotoluene has specific surface at least 208 mm/g related to a unit of granule mass. The granular explosive material (second modification) further comprises water and a surfactant, while the granular trinitrotoluene has the following disperse composition: more than 1.2 mm - at least 94 mass percent, less than 3.2 mm - at least 85 mass percent, less 5 mm - all 100 mass percent with the following component content: water 0.02-2.0 mass percent, surfactant - 0.000015-0.024 mass percent, trinitrotoluene - remaining to 100 mass percent.
