Portable gas detector for mining use

Accidents such as underground gas explosions and fires can produce large amounts of toxic and harmful gases such as CO, CO2, CH4, and consume a large amount of O2. When the concentration of toxic and harmful gases at the accident site is too high and the O2 content is low, it can endanger the lives of search and rescue personnel. Therefore, when conducting post disaster rescue underground, the air hazard of the mine environment within a certain distance that has not been reached should be detected first.

The existing methods for detecting environmental air in rescue work include short-range remote sensing monitoring, pole detection, and throwing detection, which generally have the following problems:

Short distance remote sensing monitoring: The detection distance is short, with a maximum of 30 meters; The detection of gas is single, usually only able to detect methane concentration;

Probe detection: Due to the length limitation of the probe, the detection efficiency is low, which affects the efficiency of rescue work;

Throwing detection: The operation of throwing equipment is greatly affected by human factors, with a high rate of sensor damage and a low success rate of throwing. The actual application effect is not ideal;

LGAS200 laser gas telemetry instrument is a highly reliable and portable instrument used for long-distance and rapid detection of methane and carbon monoxide gas concentrations;

This instrument adopts tunable semiconductor laser absorption spectroscopy technology, which has the advantages of no personnel contact, high sensitivity, good selectivity, fast response, no maintenance, and good long-term stability;

This product has been reviewed and inspected by legal authorities and has passed type approval. It can be widely used in places where gas leaks may occur, such as urban gas transmission and distribution pipelines, refineries, chemical plants, metallurgical industries, and power industries in the petroleum and petrochemical industries.

Portable gas detector for mining useLGAS200Measuring principle：

The front end of the telemetry instrument has an indicator laser emission window, which facilitates direct observation of the detection point during actual detection. During measurement, the instrument points to the target area (such as pipelines, walls, floors, etc.), and the laser emits a specific beam. If there is methane or carbon monoxide gas leakage on the beam path, the reflected beam will contain absorbed gas signals, which will be converged and enter the detector. The high-speed processing unit can analyze the signal to obtain the concentration of the leaked gas and display, store, and sound and light alarms in real time.
