Gas control method

Abstract

The invention belongs to the field of gas control methods, and particularly relates to a gas control method. Gas control adopts following equipment and structures: ventilation equipment, a ventilationpipeline, branch pipelines, air volume detection equipment, scattered sprayers, a bearing seat, a fan blade and an exhaust hole, and an installation method of the gas control equipment and structurescomprises the following steps that S1, firstly, the ventilation pipeline is fixedly installed at a certain height in a roadway in advance, and during installation, the ventilation pipeline is arranged at the position where the pipeline is not prone to being damaged. According to the gas control method, the design is reasonable, especially the installed scattered sprayers and the branch pipelinesinstalled at each point can disperse gas in a large range, the gas concentration is reduced, when the ventilation equipment cannot work, the standby ventilation equipment can be started in time, so asto continuously send fresh air into the roadway, so that the occurrence of gas accidents is better prevented, two ventilation equipment is alternatively used, and the equipment can be prevented fromheating due to long-time working and shortening the service life of the equipment.

Description

technical field [0001] The invention belongs to the field of gas control methods, in particular to a gas control method. Background technique [0002] Mine gas is a harmful gas that must be encountered in coal mine production. In the process of coal mine production, along with the production, gas gushes out into the production space, posing a threat to underground production. Regardless of the amount of gas gushing out, it has always been a mine The most important source of danger in production is the first of the five natural disasters in coal mines. [0003] Gas is the general term for harmful and toxic gases mainly composed of methane in underground tunnels. It is a mixed gas, methane accounts for more than 90%, and methane is usually alone. Its properties are "three no" gases, that is, colorless, tasteless, and odorless. The relative density to air is 0.554, slightly soluble in water, and the gas is non-toxic, but the high concentration of gas will reduce the concentrat...

Problems solved by technology

[0004] However, in the existing gas control methods, the effect of the control is poor, and it cannot better disperse and discharge the gas in each upper corner and goaf in an all-round way, and cannot monitor the gas of each point in real time. The air volume is to ensure the real-time circulation of the air volume to blow off the gas. In addition, a ventilation device is often installed during work. Such a device is easy to be damaged after long-term operation, and it cannot be repaired in time after the damage, which may easily lead to gas accumulation in the roadway. Security risks
