Abstract

The invention discloses a high detonation speed seismic explosive column and a making method thereof, and relates to the technical field of explosive formulas. The high detonation speed seismic explosive column is made through mixing, by mass, 25.0-40.0 parts of an aqueous methylamine nitrate solution with the concentration of 70-85%, 25.0-45.0 parts of ammonium nitrate, 13.0-15.0 parts of sodium nitrate, 4.0-6.0 parts of perlite, 10.0-15.0 parts of marble powder, 0.8-1.2 parts of sesbania powder, 0.1-0.3 parts of a foam stabilizer and 0.1-0.3 parts of a cross-linking agent; and the high detonation speed seismic explosive column also comprises 2.0-5.0 parts by mass of ethylenediamine dinitrate. A technical problem to be solved in the invention is providing the high detonation speed seismic explosive column.

Description

technical field [0001] The invention relates to the technical field of explosive formulations, in particular to a high detonation velocity seismic source charge column and a manufacturing method thereof. Background technique [0002] Geological prospecting is one of the important contents in geophysical prospecting. It is based on the elastoplasticity of rocks, uses explosives as the seismic source, uses seismic survey instruments to detect large earthquakes at different positions along the line, and records the data on tape for further analysis and processing. The first step in geological exploration is to solve seismic wave excitation, that is, how to ensure sufficient energy and required frequency components. At present, explosives are mostly used as seismic sources in geological exploration in my country. [0003] Adding RDX, TNT, etc. to the water-gel seismic source charge can improve the explosive performance of the explosive to varying degrees, but it will bring abo...
