Embodiment 1

[0028] The hole-filling hydraulic inorganic powder foaming material of this embodiment is prepared according to the raw materials of No. 1-3 in Table 1-3.

[0029] The application of the cavity-filling hydraulic inorganic powder foaming material of this embodiment is used for large-volume filling of downhole caving areas, cavities and racks. It proceeds as follows:

[0030] 1. Add the raw materials into the mixer, stir and mix for 15 minutes, and the dry powder mixture is obtained;

[0031] 2. Mix the dry powder mixture prepared in step 1 with water according to the mass ratio of 1:2, and then use the screw type grouting pump for high-speed stirring and continuous output to form foam slurry, and place the foam slurry through the grouting pipeline Filling in downhole caving areas, cavities and large-volume positions behind racks.

Embodiment 2

[0033] The hole-filling hydraulic inorganic powder foaming material of this embodiment is prepared according to the raw materials of No. 4-6 in Table 1-3.

[0034] The application of the hole-filling hydraulic inorganic powder foaming material of this embodiment is used for fast filling of the upper and lower corners, and is carried out according to the following steps:

[0035] 1. Add the raw materials into the mixer, stir and mix for 15 minutes, and the dry powder mixture is obtained;

[0036] 2. Mix the dry powder mixture prepared in step 1 with water according to the mass ratio of 1:2.5, stir and output continuously through the screw type grouting pump at high speed, and make foam slurry at the mouth of the transportation pipeline, and inject the foam slurry into the upper and lower corners Filling can be completed within the pre-made frame.

Embodiment 3

[0038] The hole-filling hydraulic inorganic powder foaming material of this embodiment is prepared according to the raw materials of No. 7-9 in Table 1-3.

[0039] The application of the hole-filling hydraulic inorganic powder foaming material of this embodiment, which is used for filling and sealing coal mine fires or high-temperature areas, is carried out according to the following steps:

[0040] 1. Add the raw materials into the mixer, stir and mix for 15 minutes, and the dry powder mixture is obtained;

[0041] 2. Mix the dry powder mixture prepared in step 1 with water according to the mass ratio of 1:3, and then use the screw type grouting pump for high-speed stirring and continuous output to form foam slurry, and inject the foam slurry through the grouting pipeline Go to the underground fire area or high temperature area for filling and sealing and fire prevention and extinguishing.

Abstract

The invention relates to a composition containing an inorganic binder, as well as an application thereof, in particular to a cavity filling powdery foam material containing the inorganic binder, as well as application thereof, and aims to provide a cavity filling hydraulic inorganic powdery foam material, which has the advantages of low forming temperature, quickness in solidification, small density and high foam expansion, as well as application thereof. The inorganic powdery foam material is prepared from the following raw materials: cement, gypsum powders, coal ash powders, milled slag powders, quartz powders, silica fume, carbonate powders, a foaming agent, and coagulant powders. The inorganic powdery foam material provided by the invention has the advantages that the raw materials are easy to obtain, and the product is easy to preserve; when in use, the inorganic powdery foam material achieves high simplicity and convenience in operation, low forming temperature, quickness in solidification, small density and high foam expansion. The inorganic powdery foam material is applicable to fields such as underground filling or firefighting of coal mines, etc.

Description

technical field [0001] The invention relates to a composition containing an inorganic binder and its application, in particular to a powder foaming material containing an inorganic binder for filling holes and its application. Background technique [0002] With the development of the coal mining industry, the safety requirements for underground coal mining are getting higher and higher. At present, there are as many as 5,000 tons of organic polymer filling materials used in coal mines in my country. Such polymer materials mainly include phenolic resin filling materials, polyurethane filling materials and so on. Chinese invention patent CN103627136A introduces a polymer foaming material for coal mine filling and sealing. This foaming material has a phenolic resin structure as the main body and is mainly used for filling underground cavities and cavity positions. The organic polymer filling material has fast filling speed, high filling multiple and fast construction, and has ...
