Gas instant eliminating liquid preparing method and use method

Abstract

The invention relates to a gas instant eliminating liquid preparing method and a use method. Gas instant eliminating liquid comprises, by weight, 32% to 47% of carboxylic acid, 26%-33% of vegetable protein, 12%-18% of cane sugar, 7%-15% of alums, 7%-12% of sodium carbonate, 9%-15% of sodium bicarbonate, 4%-8% of glyodin and 5%-9% of calcium carbonate. The total weight ratio of all the mentioned components is 100%. The idea of passive prevention and treatment in the prior art is totally changed. The gas instant eliminating liquid preparing method and the use method belong to the scope of initiative prevention and treatment. Basically speaking, gas is treated before coal is exploited and drilling is carried out on the ground when a mine is constructed. The gas eliminating liquid can effectively decompose mine gas when a coal layer is in a primitive state, the concentration of the mine gas is reduced, the gas is treated to be within a safety range, and personal safety of exploiting workers is ensured.

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 gas elimination liquid. [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, Sichuan, Yunnan, G...

Problems solved by technology

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
