Embodiment 1

[0023] Mix and stir 100g of fly ash of Hangkou Power Plant, 200g of water, 10g of liquid water glass and 0.2g of sepiolite, and stir for 3 minutes to obtain a uniform and stable thixotropic new fly ash slurry.

Embodiment 2

[0025] Mix 100g of fly ash of Hangkou power plant, 200g of water, 10g of liquid water glass, 0.1g of NaOH and 0.2g of sepiolite and stir for 3 minutes. The viscosity of the slurry is 1.1×10 -3 Pa·S or so, grouting in coal gangue, the penetration radius can reach 3m.

Embodiment 3

[0027] Mix and stir 100g of fly ash of the Hangkou Power Plant, 200g of water, 10g of liquid water glass, 0.1g of NaOH, and 0.5g of sepiolite, and stir for 3 minutes to obtain a uniform and stable fly ash slurry. The slurry has good stability and is suitable for pipeline transportation. It has thixotropy and can effectively prevent the loss of slurry. It has good wrapping properties and can effectively block oxygen and extinguish fire.

Abstract

The invention discloses a novel coal ash grouting material, which is composed of specific components by mass: 1 part of coal ash, 2 parts of water, liquid water glass occupying 5% to 10% of the coal ash and sepiolite occupying 2%. to 5%.of the coal ash. Improved coal ash grout has strong adhesion performance on firing articles, can evenly and effectively cover the surfaces of the firing articles, is strong in water-retaining performance and good in fire resistance, can effectively block leakage insulate oxygen to prevent grout from losing, and is low in price, environmental-friendly, good in stability and suitable for pipeline transportation.

Description

technical field [0001] The invention belongs to the field of anti-fire extinguishing materials for coal mines, in particular to the field of anti-fire extinguishing materials for coal gangue hills. Background technique [0002] Spontaneous combustion of coal gangue hills is a relatively common phenomenon. There are 1,700 gangue hills burning in my country, most of which are in the middle and upper reaches of the Yellow River. The spontaneous combustion of coal gangue is called "flaming mountain" by the local people, which includes the degree of harm of coal gangue and also reflects the difficulty of controlling spontaneous combustion of coal gangue. Due to the large fire area, deep fire source, difficult construction on the hillside, and easy re-ignition of the fire after extinguishing, the coal gangue hill spontaneous combustion fire has not been effectively controlled, seriously polluting the environment and affecting the normal life of the surrounding residents. .
