Parallel energy gathering groove type dual energy gathering explosive charging device

Abstract

The invention discloses a parallel energy gathering groove type dual energy gathering explosive charging device. The device comprises an energy gathering tube body, wherein a storing space in which explosive can be filled is formed in the energy gathering tube body; M-shaped parallel energy gathering grooves consisting of a first energy gathering groove and a second energy gathering groove are formed in the energy gathering tube body; the parallel energy gathering grooves are capable of gathering two explosion jets to increase the jet speed; the parallel energy gathering grooves are symmetrically formed in two sides of the energy gathering tube body. The device has the beneficial effects that the M-shaped parallel energy gathering grooves consisting of the first energy gathering groove andthe second energy gathering groove are capable of gathering a jet A produced by the first energy gathering groove and a jet B produced by a second energy gathering groove in order to increase the jetspeed of an exploding product of the explosive to be 1.5-2 times that of a single energy gathering groove, thus the exploding product can act on the wall of a borehole with high energy, high densityand high pressure, and as a result, the rock cutting depth is increased, and the cutting effect is improved; the low-exploding-speed explosive can reach the cutting effect of high-exploding-speed explosive through the two parallel energy gathering grooves.

Description

technical field [0001] The invention relates to the field of energy-gathering blasting, in particular to a double-gathering charge device with parallel energy-gathering grooves. Background technique [0002] In the existing smooth blasting pre-splitting blasting technology, the energy-gathering grooves of the energy-shaping charge devices used are mostly single-structure energy-gathering grooves, and there are problems: [0003] 1. The utilization efficiency of the detonation wave of the explosive is low, because the area occupied by the single-structure energy-gathering tank is smaller than that occupied by the parallel double-energy-gathering tank, and the amount of energy conversion is small. A device that converts potential energy and kinetic energy into kinetic energy jets. The jet formed by a single-structure energy-gathering groove is only E times the detonation velocity of explosives. See the following formula: The energy density of the detonation wave can be calcula...
