Problems solved by technology

Due to the low solid content of the slurry, the particles are easy to sink and accumulate, which affects the grouting in place
[0007] 2) The moisture content of the grouting material is high, and it is easy to generate a large amount of water vapor. The flammable gas generated by coal dry distillation will increase, and at the same time, it will induce more coal gangue oxidation
[0008] 3) With the evaporation of water after grouting, it is difficult for the slurry aggregate to form a continuous and dense sealing layer, and it is easy to form air leakage channels, which will affect the oxygen insulation effect or cause coal gangue to re-ignite

Abstract

The invention belongs to the technical field of mine waste treatment and fire prevention, relating to a fire proofing and extinguishing agent composite for a mine and a preparation and use method thereof. The fire proofing and extinguishing agent composite comprises the following components in percentage by weight: 1.0-6.0wt% of glass fibre substance, 3.0-6.0wt% of lime, 3.5-6.0wt% of loess, 3.1-6.2wt% of coal ash, 0.01-0.03wt% of binding agent, 0.01-0.03wt% of water-retaining agent, 0.002-0.013wt% of dispersing agent and 80-90wt% of water. The fire proofing and extinguishing agent is non-toxic, harmless and safe to use and has the advantages of adjustable proportion, high inhibition rate and better inhibition performance. The slurry is easy to flow under the wet state and is in solid net body state after being dried, and the slurry has stronger impermeable plugging function; grouting equipment has strong adaptability, professional grouting equipment is adopted, and spraying and planting equipment can be used for construction. The slurry has big adjustable range of activity period and can be adjusted within 1-30 hours.

Description

technical field [0001] The invention belongs to the technical field of mine waste management and fire protection, and relates to a fire prevention and extinguishing agent composition and a preparation and use method thereof. Background technique [0002] Coal gangue is a solid waste with low carbon content and high ash content discharged during coal mining and processing, accounting for about 10% to 15% of coal production. A large amount of coal gangue is discharged to form a gangue hill, which not only occupies valuable land resources and destroys the natural landscape, but also spontaneously combusts, seriously pollutes the atmospheric environment of the mining area, and damages human health. Prevention and control of coal gangue spontaneous combustion is a very urgent task in the current coal industry. [0003] Spontaneous combustion of waste rock is a special combustion system, which can be divided into three types: spontaneous combustion incubation period, spontaneous ...
