Embodiment 1

[0049] Such as figure 1 As shown, the embodiment of the present invention provides an application method based on high hydrosol condensates in coal mines, which is applied to underground mines, and specifically includes the following steps:

[0050] S1: Use inorganic substances and water according to different predetermined ratios to form high hydrosol coagulates with different concentration levels from No. 1 to No. 11;

[0051] Among them, No. 1-5 high-water sol condensates are made of inorganic substances and water in a one-time gelling process. The finished product is like jelly, which cannot be broken by water or wind, and cannot be restored to its original shape after being gelled;

[0052] Specifically, the No. 1 gel proportioning raw material is sodium silicate tetrahydrate: water: dilute sulfuric acid (28%)=3:100:1,

[0053] No. 2 gel proportioning raw material is sodium silicate tetrahydrate: water: dilute sulfuric acid (28%)=1:100:0.33,

[0054] No. 3 gel proportio...

Embodiment 2

[0071] In Embodiment 2, for the same structure as in Embodiment 1, the same symbols are given, and the same description is omitted. The difference between Embodiment 2 and Embodiment 1 is that, as figure 2 As shown, the embodiment of the invention provides a method based on the application of high hydrosol condensates in coal mines, which is specifically applied to open-pit mines and coalfield ground fire areas, including the following steps:

[0072] S1: Use inorganic substances and water according to different predetermined ratios to form high hydrosol coagulates with different concentration levels from No. 1 to No. 11;

[0073] Among them, No. 1-5 high-water sol condensates are made of inorganic substances and water in a one-time gelling process. The finished product is like jelly, which cannot be broken by water or wind, and cannot be restored to its original shape after being gelled;

[0074] Specifically, the No. 1 gel proportioning raw material is sodium silicate tetra...

Abstract

The invention discloses an application method based on high hydrosol condensations in a coal mine, and belongs to the technical field of coal mine exploiting. The method comprises the following stepsthat inorganic substances and water are mixed according to the different proportions, the high hydrosol condensations with different concentration ladders can be formed, conveying pipelines are laid in the coal mine, outlets of the conveying pipelines are mounted on reserved use positions, and the high hydrosol condensations with the different concentration ladders are conveyed to the reserved usepositions in a one-to-one corresponding manner through the conveying pipelines. Through the method, the high hydrosol condensations with the different concentration ladders can be used to be conveyedto the different use positions through the conveying pipelines, the problems that due to un-tight plugging wind in the coal mine production, gas drainage efficiency is low, and spontaneous combustionis caused can be solved, and the possibility of giant disaster happening can be reduced.

Description

technical field [0001] The invention relates to the technical field of coal mine mining, in particular to an application method based on high hydrosol condensates in coal mines. Background technique [0002] At present, there are five natural disasters in coal mine safety production, namely water, fire, gas, coal dust, and roof caving. Due to the limitation of mining level, equipment conditions and geological factors, in the process of coal seam mining, enough coal pillars of various types should be left between each working face and another working face to support the roof and protect the upper coal seam The roadway ensures safe production and recovers as much coal resources as possible. However, these coal pillars will remain underground forever and cannot be extracted, which also causes a large waste of resources. [0003] In the prior art, the 110 coal mining method and the N00 coal mining method commonly used in coal mining can recover coal resources to the greatest e...
