Seismic charge with low detonation velocity

Abstract

The invention relates to a seismic charge with low detonation velocity. The process takes an expanded ammonium nitrate explosive with the low detonation velocity as a main charge to produce the seismic charge with the low detonation velocity. The invention provides an environmentally friendly formulation process for the seismic charge with the low detonation velocity, which can effectively improve the resolution of the obtained map data. The seismic charge with the low detonation velocity comprises the following components: 83.0% to 87.0% of expanded ammonium nitrate, 3.0% to 4.0% of wood flour, 2.0% to 3.0% of compound oil phase, 4.0% to 5.0% of high-energy additive and 6% to 8% of diluent.

Description

Technical field: [0001] The invention relates to a low-detonation-velocity seismic source powder column. The technology uses low-detonation-velocity expanded ammonium nitrate explosive as the main charge to make a low-detonation-velocity seismic source powder column. Background technique: [0002] The seismic source charge is a shaped charge used for geological exploration by filling the shell (made of plastic or other materials) with industrial mixed explosives, which explode to generate seismic waves. In the existing geological exploration, many kinds of explosives inside the seismic source charge column have been used, such as powdered ammonium ladder explosives, colloidal explosives and emulsion explosives. Among these industrial explosives, ammonium-ladder explosives are the most used in seismic source charges. According to the difference in density and detonation velocity, the existing seismic source grains in my country are divided into low-density seismic source gra...
