Problems solved by technology

Polyurethane and other organic foam sealing materials have a high reaction temperature, violent reaction, a large amount of reaction heat is released, a strong odor is generated, the reaction speed is too fast, the initial setting time cannot be adjusted, the sealing length is not easy to control, and the sealing strength Low, not dense, easy to leak, high cost
The existing cement seals the holes, the cement sets slowly and is easy to shrink and separate water, resulting in poor sealing performance, and it is impossible to seal the micro-cracks

Abstract

The invention provides a mineral inorganic hole-sealing material. The mineral inorganic hole-sealing material is prepared from, by mass, 10-87% of cement, 10-50% of pulverized fuel ash, 1-20% of alum,1-20% of accelerator and 1-20% of gypsum powder. The mineral inorganic hole-sealing material is small in density, low in mass, high in plasticity and permeability and high in quick solubility, is noteasily caked, is high in pressure resistance, high in pressure resistance and high in setting rate and has expansibility after solidification. The invention further provides a preparing method and using method of the mineral inorganic hole-sealing material, and the preparing method of the mineral inorganic hole-sealing material is easy to operate and implement.

Description

technical field [0001] The invention belongs to the technical field of sealing materials, and in particular relates to an inorganic sealing material for mines, a preparation method and a use method thereof. Background technique [0002] Coal is the main energy source in our country. However, the mining process is accompanied by many disasters and accidents. Among them, the early drainage of coal seam gas is an important means to prevent gas. The better the effect of pre-drainage, the better the drainage effect. The higher the ratio, the better the environment during mining and the lower the possibility of accidents. In all aspects of gas drainage, drilling and sealing is a key part, and the quality of the sealing will seriously affect the effect of gas drainage. [0003] At present, the hole sealing technology of coal seam gas drainage drilling is to use organic materials or inorganic materials for sealing, typical examples are organic foam material-cement sealing, bag-type...
