Facility for detecting methane concentration of coal mine

Abstract

The invention discloses a facility for detecting the methane concentration of a coal mine. The facility comprises a case. The case comprises a front cover and a rear cover, which is matched with the front cover. The front cover and the rear cover form a cavity structure. A processor is arranged in the case. The bottom of the case is provided with a laser gas detection assembly. An alarm lamp is arranged on the surface of the laser gas detection assembly. A keyboard, a display screen, a buzzer, and a printer are arranged on the front cover. The provided facility solves the problems that a minemethane detection device cannot accurately detect methane, the detection precision is low, and the detection device needs frequent calibration. The invention provides the facility for detecting the methane concentration of a coal mine. The gas is detected by laser, the detection precision is improved, the calibration period is prolonged, the work load of calibration staff and the work for maintaining a monitoring system are largely reduced, the number of workers is reduced, the work efficiency is improved, and great economic benefits are generated.

Description

technical field [0001] The invention relates to methane detection, in particular to equipment for detection of methane concentration in coal mines. Background technique [0002] With the continuous development of the national economy, the demand for coal is also increasing day by day, but to ensure the smooth progress of the mining industry, safety is very important. Historically, methane explosions, one of the main causes of coal mine accidents, have occurred frequently, causing heavy casualties and economic losses. The lessons have been profound. For this reason, coal mine production and management units attach great importance to coal mine methane monitoring, and at the same time carry out coal mine methane detection work. It becomes a necessary condition for coal mines to be able to produce. At present, the methane alarm system used in domestic coal mines has a certain scale, but its detection accuracy is low, and the detection range is narrow, it is difficult to detect...
