Mining high efficiency blister mud dedusting additive

Abstract

Belonging to the field of blast mining, the invention specifically relates to a mining high efficiency blister mud dedusting additive, which is composed of 15-25% of a JFC penetrating agent, 5-10% of superabsorbent resin, 0.4-2.5% of sodium dodecyl sulfate, 1.0-1.5% of a metal washing agent, 0.5-1.0% of sodium hexametaphosphate, and the balance water. The additive is prepared by the steps of: first adding 5-10% of superabsorbent resin into a solvent and stirring them to form a homogeneous solution; then adding 15-25% of a JFC penetrating agent and 0.4-2.5% of sodium dodecyl sulfate into the above saturated solution in proportion; and adding 1.0-1.5% of a metal washing agent, 0.5-1.0% of sodium hexametaphosphate, and the balance water into the mixture, and continuing stirring for half an hour. With strong dedusting capability, the additive of the invention has a comprehensive dedusting rate up to over 80%, and the removing rate for respirable dust less than 5 micrometers can reach over 70%. Thus, the additive provided in the invention is suitable for dedusting in mine exploitation and stone removal, as well as coal mine explosion and exploitation.

Description

Technical field: [0001] The invention belongs to the field of blasting mining, and in particular relates to a mine-used high-efficiency water foam mud dust-reducing additive for preventing mine dust from being generated. Background technique: [0002] Water blasting technology has been widely used at home and abroad, and has achieved many results, and has been more and more widely used. This method is: relying on the heat generated by the blasting, the water in the blister mud bag is rapidly atomized and the coal dust generated after the blasting is condensed, increased, increased in weight, and settled to achieve the purpose of falling, and it can effectively reduce the toxic and harmful The concentration of gas is an active and effective dust-proof technology, but because the dust-repelling component is a single natural water, the interfacial tension of the water after blasting is high, it is not easy to atomize or the degree of atomization is not high, so it cannot fully ...

Problems solved by technology

This method is: relying on the heat generated by the blasting, the water in the blister mud bag is rapidly atomized and the coal dust generated after the blasting is condensed, increased, increased in weight, and settled to achieve the purpose of lowering, and it can effectively reduce toxic and harmful substances. The concentration of gas is an active and effective dust-proof technology, but because the dust-repelling component is a single natural water, the interfacial tension of the water after blasting is high, it is not easy to atomize or the degree of atomization is not high, so it cannot fully wet the dust , Dust reduction effect, penetration, adsorption, wetting force, etc. are poor, resulting in unsatisfactory dust reduction effect
