High resolution ratio medicament for hypocenter charge column and producing method thereof

Abstract

The invention relates to a high resolution ratio seismic explosive column medicament and a production method thereof, which pertains to the technical field of geological exploration. The seismic explosive column medicament has main ingredients of oversized compost of 40 mesh oversize material single-base propellant, undersized compost of 60 mesh single-base propellant, ammonium nitrate and dibutyl phthalate or dimethyl phthalate or diethyl phthalate. The medicament can control slow release of energy when exploded and reduce explosion velocity of the seismic explosive column; seismic wave excited by the medicament has slow degradation of energy and stronger penetrability, thereby resulting in stronger reflection wave and higher resolution ratio, and being especially suitable for geological exploration of soft stratum.

Description

(1) Technical field [0001] The invention belongs to the technical field of geological exploration, and in particular relates to a high-resolution seismic source grain used for exciting seismic waves in exploration. (2) Background technology [0002] In the geological exploration work, the seismic wave is excited by the explosion of the source charge (also called the source bomb) buried below the surface, and the exploration purpose is achieved by receiving the reflected waves of different geological layers by the receiving instrument. [0003] As a high-resolution seismic source charge for exploration, high-detonation-velocity source charge is generally used to excite seismic waves, and to disturb with higher excitation energy to achieve the purpose of clear reception of reflected waves. In terms of the composition of the agent, it is composed of military explosives and high-energy metal powder. Its main chemical components are: TNT, ammonium nitrate, and aluminum powder. Th...

AI Technical Summary

Problems solved by technology

[0007] In order to reduce the detonation velocity of the seismic source charge, various methods have been adopted in practice, including reducing the charge density of the explosive and maintaining its detonation at a low speed, but the detonation and detonation continuity performance is not ideal

There is also the use of electronic components to control the detonation time, segmental delay blasting, and low disturbance in the overall blasting, which is difficult to operate in actual use and the effect is not obvious

There is also the spiral shape of the explosive to reduce the axial detonation velocity, but it is also difficult to achieve a low detonation velocity
