Embodiment 1

[0095] A series of blasting experiments were carried out at the Braeside quarry near Warwick, Queensland, Australia, to evaluate the detonation performance of products manufactured with rubber granules as a component and compare them with ANFO. In particular, the VOD of different product mixtures including those explosive compositions of the present invention was tested.

[0096] product inspection:

[0097] Seven products were manufactured for a series of tests. These explosives are mixed by hand in 20kg / batches on site. Following standard industry recipes, mix ANFO (ammonium nitrate / fuel oil) and ANRUB (linear rubber and ammonium nitrate blend). Products 4-7 are explosive compositions of the present invention and are manufactured according to ANRUB but with the addition of minor components of fuel oil and polymer binder (polymethacrylate, commercially available under the name Anfomul P3000 alkanolamine derived material) to improve the adhesion of rubber and oxidizing agen...

Abstract

An explosive composition is provided comprising an explosive agent, a solid fuel and a polymeric adherent, wherein the explosive agent, solid fuel and polymeric adherent are dispersed throughout the composition.

Description

technical field [0001] The invention relates to the field of explosive compositions, in particular to an explosive composition containing solid fuel adhered to an explosive and a production method thereof. Background technique [0002] The most commonly used explosive in mining is a mixture of ammonium nitrate and fuel oil (ANFO). Fuel oil is usually No. 2 fuel oil, but diesel, kerosene and vegetable oil are also used. ANFO is a high energy explosive that produces a large shock wave component as part of the released blast energy. [0003] Impact components are somewhat inefficient in rock blasting and produce a high proportion of fine dust and debris, which is obviously not desirable from a safety and environmental point of view. When mining valuable materials such as gold or diamonds, it is also necessary to reduce the shock wave component to reduce some damage or loss to the material. The heave component of the blast energy effectively does most of the necessary work in...
