The existing methods of gas control are only passive prevention and control, such as draining the gas in the coal seam, the extracted gas must pass through pipelines, drainage pumps, etc. At the same time, the gas that does not meet the requirements for power generation can only be discharged into the ground atmosphere. It not only affects the environment, but also poses safety hazards
[0008] The patent document with application number 200410048015.1 discloses a coal mine gas explosion outburst control method and its matching gas disintegrant. The gas disintegrant is an aqueous solution composed of acetic acid and yeast. The main component of coal mine gas is methane (CH4). Although it is the simplest organic compound, because of its stable and inactive molecular structure, it is not easy to have physical and chemical interactions with other substances under normal circumstances. Only under high temperature and high pressure can it chemically interact with certain material components. Forming high-temperature conditions, it is only possible to promote the physical and chemical reactions between methane and other material components under high-pressure conditions with the help of catalysts and co-solvents to achieve the purpose of dissolving methane. Therefore, only the role of acetic acid and yeast It is difficult to complete the dissolution of gas well

The invention provides a method for preparing coal mine gas instant eliminating liquid and a method for using the coal mine gas instant eliminating liquid. The coal mine gas instant eliminating liquid is prepared from the following components, by weight, 33-46% of beer, 31-41% of acetic acid, 16-22% of vegetable protein, 8-13% of cane sugar, 6-9% of apple green agents, 5-11% of alums and 4-13% of sodium carbonate. The sum of the ratios of the components by weight is 100%. The conception of passive prevention and treatment in the prior art is completely changed, the methods belong to the category of active prevention and treatment, basically, gas is treated before coal is mined, drilling can be conducted on the ground when mine construction is conducted, the gas eliminating liquid can effectively decompose coal mine gas when a coal bed is in the initial condition, therefore, the concentration of the coal mine gas is reduced, gas is treated to be within a safety range, and personal safety of digging workers is guaranteed.
Description
[0001] technical field [0002] The invention relates to the technical field of coal mine gas elimination, in particular to a method for assembling and using an instant liquid for eliminating coal mine gas. [0003] Background technique [0004] Coal is an important basic energy in my country, accounting for about 70% of the country's primary energy consumption. It has an important strategic position in the national economy. Production conditions have improved, but there are still problems such as extensive growth, frequent safety accidents, serious waste of resources, and lagging behind in environmental governance. In particular, the frequent occurrence of safety accidents has attracted worldwide attention. Nearly half of the key state-owned coal mines are high-gas coal mines and gas Prominent mines, high-gas mines account for more than 56% of domestic mines, especially in Huainan, Huaibei Mining Bureau, Henan Pingdingshan Mining Bureau, Shaanxi Tongchuan Mining Bureau, Sich...
