Abstract: The present disclosure relates to an apparatus and method for controlling detonator blasting based on a danger radius, the apparatus including a danger radius setting unit that sets a danger radius for a detonator or a communication module, a blasting area setting unit that sets a blasting area in which a preset danger radius is reflected in a location value input during registration of the detonator or the communication module, an equipment location determination unit that determines a location of equipment possessed by an operator, and a blasting start control unit that controls so that blasting of the detonator is allowed only when the equipment is not located within the set blasting area as a result of the determination.

Abstract: A method for reducing blasting vibration of tunneling includes the steps of: dividing the cutting holes into several groups according to different cutting methods; conducting layout and test blasting on one group of cutting holes; testing blasting parameters for the layout and test blasting; calculating an interval t; conducting layout and test blasting on at least two groups of cutting holes again; testing blasting parameters for the layout and test blasting of each group for the second time; taking the minimum interval t of each group as the interval for formal blasting of the remaining groups of cutting holes. The use of the characteristics of the wave in the invention can superpose the peaks and troughs of the vibration wave, and further cancel out mutually; reduce the peaks of the blasting vibration and fill the troughs of the blasting vibration.

Abstract: The invention relates to the field of blasting operations. The mechanical stemming device has the following elements. A sleeve having expandable structures and, positioned in a cavity thereof, an element that has wedge-type surfaces. Conductors are arranged in the elements of the stemming plug in functional channels. The sleeve has an end surface that faces the mouth of the hole and that forms a thrust surface to allow action on this surface as the expandable structures are wedged into place. The element is equipped with a structural and functional stopping and gauging tool that has reference elements. The invention allows a stemming device to be secured at a set distance from the mouth of a hole while completely avoiding it coming into contact with the explosive.

Abstract: An explosive system for fracturing an underground geologic formation adjacent to a wellbore can comprise a plurality of explosive units comprising an explosive material contained within the casing, and detonation control modules electrically coupled to the plurality of explosive units and configured to cause a power pulse to be transmitted to at least one detonator of at least one of the plurality of explosive units for detonation of the explosive material. The explosive units are configured to be positioned within a wellbore in spaced apart positions relative to one another along a string with the detonation control modules positioned adjacent to the plurality of explosive units in the wellbore, such that the axial positions of the explosive units relative to the wellbore are at least partially based on geologic properties of the geologic formation adjacent the wellbore.

Abstract: A detonator system is provided for use with explosives that utilizes two subsystems. A first subsystem functions as a non-explosives based detonator, which does not contain any explosives. The second subsystem is an initiating subsystem, which includes an initiating pellet. To set off an explosive event, the non-energetics based detonator is coupled to the initiating subsystem and the non-energetics based detonator is commanded to provide a suitable signal to the initiating subsystem that is sufficient to function the initiating pellet. Further, the initiating subsystem can be integrated directly into an associated explosive such as a booster that has been configured to receive the initiator subsystem without changing the hazard class of the booster.
