Description
Technical Field
The invention relates to the field of coal mines, in particular to a roadway gas and air purification system.
Background
Mine gas is a major unsafe factor in the coal mine production process. The gas is the general name of various gases gushing from coal and rocks in the production process of coal mines. Mine gas is complicated in composition, contains other hydrocarbons such as ethane and propane in addition to methane, and carbon dioxide and hydrogen sulfide gas, and is easily accumulated in the upper part of a roadway, so that when the gas concentration in the roadway is checked, the vicinity and corners of the roadway roof should be heavily checked. The gas has small molecular diameter and strong permeability which is 1.6 times of that of air. Although the gas is nontoxic, if the concentration of the gas in the air in the mine exceeds 40 percent, people can die in the room due to oxygen deficiency. The gas has combustion and explosiveness, and after the gas and the air are mixed to reach a certain concentration, the gas can be combusted or exploded when meeting fire, so that the gas threatens a mine greatly. Once gas explosion happens underground, high temperature, high pressure and a large amount of harmful gas are generated to form shock waves with strong destructive power, so that serious casualties are caused, mine roadways and underground equipment can be seriously destroyed, and coal dust explosion and underground fire can be caused.
