Fluid-state water-gel explosive

Abstract

The invention discloses a fluid-state water-gel explosive. The flow-state water-gel explosive is prepared from the following raw materials in percentage by mass: 36%-46% of methylamine nitrate, 10%-13% of solid ammonium nitrate, 20%-30% of liquid nitrate, 12%-15% of solid sodium nitrate, 0.5%-1% of guar gum, 0.8%-1.2% of a foam stabilizer, 0.8%-1% of a cross-linking agent, 0.1%-0.3% of a foaming agent, 0.1%-0.2% of an accelerant and 8%-12% of distilled water. The fluid-state water-gel explosive is a fluid-state water-gel-based explosive, compared with other explosives, the fluid-state water-gel explosive has good fluidity and is convenient to use, the safety level of the fluid-state water-gel explosive is not lower than the safety level of secondary coal mine allowable explosives, and compared with rock-type water-gel explosives, the fluid-state water-gel explosive is higher in power and better in use effect; and meanwhile, the fluid-state water-gel explosive has the advantages of lowproduction cost, simple production process, good safety, capability of meeting the use requirements of special blasting environments and the like.

Description

technical field [0001] The invention relates to the technical field of explosives, in particular to a fluid water gel explosive. Background technique [0002] Traditional water-gel explosives and emulsion explosives cannot meet the needs of oil and gas mining in coal mines and oil mines in special environments. Oil and gas mining requires secondary blasting of the same blasthole. After normal blasting, the rocks around the blasthole will be broken and irregular Collapsing holes, in this case, it is almost impossible to drill holes for secondary blasting, but liquid water gel explosives are not affected by collapsed holes and fragmented rock blocks, and can enter through the gaps and fissures between rock blocks Go to the inside of the blast hole and carry out secondary blasting. [0003] Because traditional water-gel explosives do not have the characteristics of fluidity, they have been unable to enter the market of some special industries and special users. The research an...

[0002] Traditional water-gel explosives and emulsion explosives cannot meet the needs of oil and gas mining in coal mines and oil mines in special environments. Oil and gas mining requires secondary blasting of the same blasthole. After normal blasting, the rocks around the blasthole will be broken and irregular Collapsing holes, in this case, it is almost impossible to drill holes for secondary blasting, but liquid water gel explosives are not affected by collapsed holes and fragmented rock blocks, and can enter through the gaps and fissures between rock blocks Go to the inside of the blasthole for secondary blasting

[0003] Because traditional water-gel explosives do not have the characteristics of fluidity, they have been unable to enter the market of some special industries and special users. The research and development of liquid water-gel explosives has officially developed a new type of water-gel explosives for this special situation. The rubber explosives market is a supplement to the products of the civil explosives industry and expands the scope of the civil explosives industry. Although liquid explosives have a long history, various production methods and easy access to raw materials, among civil explosives, Liquid explosives have always been a blank

At present, explosives commonly used in the category of civil explosives mainly include water gel and emulsion explosives. The common product forms are solid, which are only suitable for filling and blasting straight holes, and cannot meet the needs of special blasting environments.
