Abstract

The invention relates to a formula technology of low-detonation-velocity seismic explosive columns. The technology adopts a low-detonation-velocity puffed ammonium nitrate explosive as a main charge to prepare the low-detonation-velocity seismic explosive columns. The formula of the low-detonation-velocity seismic explosive columns comprises 83.0-87.0% of puffed ammonium nitrate, 3.0-4.0% of wood powder, 2.0-3.0% of composite oil, 4.0-5.0% of a high-energy additive and 6-8% of a diluent.

Description

Technical field: [0001] The invention relates to a formulation process of a low-detonation-velocity seismic source charge. The process uses a low-detonation-velocity expanded ammonium nitrate explosive as the main charge to make a low-detonation-velocity seismic source charge. 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 ...
