Abstract

The invention relates to an expired propellant-containing water-gel explosive-filled seismic charge and a preparation method thereof and relates to the technical field of explosives. A water-gel explosive is used as a base and an expired propellant as a sensitizer is added into the base for formula adjustment so that the expired propellant-containing water-gel explosive-filled seismic charge is prepared. The expired propellant-containing water-gel explosive-filled seismic charge comprises, by weight, 10-15 parts of water, 16-34 parts of ammonium potassium nitrate, 5-25 parts of an expired propellant, 35-50 parts of ammonium nitrate, 0.6-1.2 parts of a gallant, 5-7 parts of sodium nitrate, 0.03-0.12 parts of sodium nitrite and 0.05-0.1 parts of a cross-linking agent. Compared with the existing seismic charge, the expired propellant-containing water-gel explosive-filled seismic charge reduces a product preparation cost, increases novel types of seismic charges and satisfies wide user demands. The expired propellant-containing water-gel explosive-filled seismic charge has an environmentally friendly formula, the processing process can be controlled easily, product quality reliability is high and storage performances are stable. The expired propellant-containing water-gel explosive-filled seismic charge belongs to a non-TNT seismic charge, produces less smoke after explosion and does not damage the human body and environment.

Description

technical field [0001] The invention relates to the technical field of explosives, in particular to a seismic source charge column filled with decommissioned gunpowder and water-gel explosives suitable for seismic exploration sources in medium and high impedance geological conditions and a preparation method thereof. Background technique [0002] The source charge is a blasting device that uses explosives as the source to excite seismic waves. The source charge is mainly used for geophysical exploration of oil, natural gas, coal, minerals, and deep-water reef-breaking operations. According to the charge density, it can be divided into low-density and medium-density. And high-density three, using the principle of seismic wave exploration, can detect various underground mineral deposits. The source charge is composed of shell, explosive and booster charge (sensitizer), which can be divided into: ammonium ladder explosive source charge, colloidal explosive source charge, emulsi...
