HOLE CHARGE AND METHOD OF ITS FORMATION Russian patent published in 2000 - IPC

Abstract RU 2144911 C1

FIELD: hole charges and their formation. SUBSTANCE: hole charge contains solid fuel and oxidizer in the form of dinitrogen tetroxide located in closed space formed by airtight hose so that free space between fuel particles is filled with oxidizer at their stoichiometric ratio. Method of formation of hole charge includes location in hole of hose from film material, filling of hose with solid fuel, installation in hole of intermediate detonators with initiating means. In so doing, made above surface of fuel is screening layer from inert material by filling gravel and peddle into hole. Then, dinitrogen tetroxide is poured and hose is sealed. EFFECT: safe formation of charge in hole from available and economic components, ensured composition uniformity due to uniform distribution of liquid oxidizer in solid fuel. 4 cl, 1 dwg, 2 tbl
