DEVICE FOR DETERMINING detonation velocity explosive charge (optional)

摘要

The invention relates to a measuring technique of determining the speed and the detonation of explosives may be used in blasting operations under industrial conditions and in the scientific and research purposes. Summary of the utility model: An apparatus for determining the velocity of detonation of explosive charges in the coating or the well consists conductor detonation pulse (waveguide or waveguide + detonating cord) of equal length, introduced into the explosive charge is perpendicular or parallel to its longitudinal axis at fixed distances from each other, electrocontact sensors on the "closure" placed inside the waveguide channels at their ends at a predetermined distance from each other connected to the multicore cable Numeric single- or multi-hop electronic time meter, start and stop of which the signals from the sensors are energized when the passage of the shock wave waveguide, and the velocity of detonation of the explosive charge is calculated from the base and the operating time interval length electrocontact sensors according to the formula: Where: D _BB - velocity of detonation of the explosive charge, m / s; L _BB - charging the length of explosive (the base) between the centers of the waveguides installation, m; Δτ - switching time interval of two adjacent electric contact sensors at the ends of the waveguides, installed on a measuring base, p. The proposed device allows to optimize charge parameters to plan and manage the explosive energy for blasting operations in quarries. 2 independent. n. Formula 2 FIG.
