Abstract

The main explosive as main part of the seismic source explosive column comprises TNT, ammonium nitrate, wood powder and organic or inorganic surfactant in the weight ratio of 25-40 to 60-70 to 0-5 to 0-2. The organic or inorganic surfactant is the mixture of paraffin, fluoric surfactant and graphite in any proportion, and the fluoric surfactant is CnF(2n+1)COOM, where n is 8-13 and M is Li ion, Na ion, ammonium ion or H ion. The production process of the main explosive is to mix the said materials and plastify inside one open-mouthed plastic pot at 81-90 deg.c for 10-25 min. The product of the present invention has high explosion speed not lower than 5000 m / s and density not lower than 1.40 g / cu cm, and can meet the requirement of seismic exploitation under different conditions.

Description

technical field [0001] The invention relates to a main charge formulation and a production process of a seismic source powder column used in special engineering blasting such as geophysical exploration and underwater blasting. Background technique [0002] The source charge is a shaped charge that is filled with explosives in a plastic shell to provide a source for seismic exploration. In the prior art, when ammonium-ladder explosive-type seismic source charges are manufactured, pure TNT or ammonium nitrate and wood flour mixed explosives containing more than 50% of TNT are usually used to be packed by pressing or screw extrusion, and the produced seismic source charges have high TNT content. The cost is high, the environment is seriously polluted, and it is harmful to the health of the operators. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the high TNT content in the existing seismic so...
