Abstract
A slurry explosive composition which contains fibrous material as a rheology modifying agent.
Claims15
A slurry explosive composition which comprises at least one inorganic oxidizing salt, a liquid solvent disperser or carrier for said salt, fuel material, and 0.001% to 3% by weight of a rheology modifying agent in the form of fibrous material the fibres of which are thread-like bodies or filaments that at least in part comprise or can be derived from material selected from the group consisting of animal tissue, vegetable tissue, resinous material, polymeric material and minerals, and the ratio of the longitudinal dimension to the transverse dimension of said fibres being at least 10:1.
A process for the manufacture of a slurry explosive composition which process comprises forming an explosive mixture comprising at least one inorganic oxidizing salt, a liquid solvent disperser or carrier for said salt, fuel material, and to said mixture adding 0.001% to 3% w/w of the said composition of material which is formed of fibres the said fibres having a ratio of longitudinal dimension to transverse dimension of at least 10:1 and being thread-like bodies or filaments that at least in part comprise or can be derived from material selected from the group consisting of animal tissue, vegetable tissue, resinous material, polymeric material and minerals and incorporating said fibrous material into said composition in a manner such that the rheological properties of the said composition are modified.
