Problems solved by technology

[0004] However, the above invention is only an emergency response measure when the coal mine gas suddenly exceeds the standard, and is not suitable for the control of lower concentration gas in the coal mine at ordinary times.
However, coal mine gas exceeding the standard and explosion often happens in an instant, and it is often too late to implement emergency preventive measures

Embodiment 1

[0023] Devices used to store gas liquids for coal mine gas treatment, such as figure 1 As shown, a closed container is jointly formed by the upper cover 5 and the casing 6 . The bottom of the box body 6 is a sandwich structure, and an electric heating plate 8 is installed inside, and a light source 9 is also installed in the box body, and the electric heating plate 8 and the light source 9 are jointly connected on a power supply. A liquid inlet 3 is arranged on the upper cover 5 , and a liquid outlet 7 is arranged at the bottom of the box body 6 . On loam cake 5, also be provided with several exhaust holes 2, spring pressure regulating valve 4 is installed in the exhaust hole 2, is provided with guard net cover 1 above. The liquid is added into the box body 6 through the liquid inlet 3, and after being heated by the electric heating plate 8, the volatile gas is discharged into the mine shaft through the exhaust hole 2 on the upper cover 5.

[0024] The liquid that adds in th...

Abstract

A liquid for harnessing coal-mine gas is composed of water solution of phosphoric acid three (2, 3-) ester, fluohydric acid, sodium hypochlorite. The liquid can be heated and volatilized to the mine, can reduce the mine temperature, prevent gas from burning and explosion, reduce mine dust concentration, and effectively harness the gas in the mine and improve the mine safety.

Description

Technical field [0001] The invention relates to a substance for controlling coal mine gas, in particular to a liquid substance. The invention also relates to a device for storing the substance. Background technique [0002] Gas is a flammable, explosive and harmful gas produced in the production process of coal mines. At present, coal mines mainly use monitoring instruments to monitor the concentration of gas in real time, and exhaust the gas through ventilators to reduce the concentration of underground gas. This method cannot effectively control the gas. When the gas concentration exceeds the standard, the underground personnel can only be evacuated urgently and the underground ventilation should be enhanced to disperse the gas. It cannot be used to prevent gas explosion. [0003] Chinese patent 03126296.1 discloses a liquid for preventing gas explosion, which is to mix multiple refrigerants and fire extinguishing agents into a pressure vessel for use. When the undergrou...
