A kind of gel type chemical gun clay and preparation method thereof

Abstract

The invention relates to a gel-type chemical stemming and a preparation method thereof. The chemical stemming is mainly suitable for the mine blasting engineering with the existence of gas and smoke dust and is used for blocking perforations. The chemical stemming is mainly used for solving the problems of high fume and harmful gas content, endangering of human body health and poor gel stability of the sodium silicate-ammonium salt stemming for blocking perforations in the prior art. The gel-type chemical stemming provided by the invention comprises the following components in percentage by weight: 3.0-5.3% of aluminum sulfate, 0.5-1.0% of gel stabilizing agent, 15-25% of sodium silicate and 69-80% of water. The preparation method of the stemming comprises the following steps of: (1) preparing an aluminum sulfate solution; (2) preparing a gel stabilizing agent; (3) preparing a sodium silicate solution; (4) mixing and packaging in bags; and (5) forming gel. The chemical stemming is non-toxic, tasteless, capable of extinguishing gas smoke, extinguishing dust, reducing blasting fume and reducing harmful gas content, good in gel stability, as well as is healthful and safe.

Description

Technical field: [0001] The invention relates to a kind of blasting clay used in the field of blasting, in particular to a gel-type chemical blasting clay used in coal mine drilling and blasting and a preparation method thereof. Background technique: [0002] At present, when coal mines are perforated and shot blasted, usually yellow mud or water blast mud is used as the material for blocking the blast holes. The use of yellow mud to block the blast hole has low plugging strength, slow filling speed, poor dust suppression effect, and the smoke and dust are difficult to dissipate. There are relatively large dust, blast smoke and harmful gases. The amount of gas, smoke, dust, and gun smoke produced in the blasting project is relatively large, which increases the content of harmful gases in the air and slows down the smoke elimination speed. It will affect the health of operators and affect the progress and speed of construction. The function of the gun mud is to ensure the f...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims to overcome the problems existing in the background technology that the existing water glass-ammonium salt gun mud gun smoke and harmful gas content that block the blast hole affect the sense of smell of the operator, endanger human health and poor stability of the gel, and provide a new solution. A gel-type chemical blasting mud, which is non-toxic and tasteless, can reduce the gas ignition temperature, eliminate gas smoke, dust, reduce blast smoke, reduce harmful gas content, environmental protection and safety, and good gel stability. The invention also provides a method for preparing chemical clay
