TWY Coal Seam Gas Outburst Hazard Forecast Instrument Product Manual
I. Product Overview
The TWY Coal Seam Gas Outburst Hazard Forecast Instrument is a mining intrinsically safe detection device specifically designed for coal mine safety production, suitable for the following scenarios:
? Measurement of initial gas emission rate from boreholes
? Determination of gas emission decay coefficient from boreholes
? Detection of desorption gas pressure
? Daily prediction of gas outburst risks in rock cross-cut coal uncovering and mining faces
This instrument integrates an intelligent measurement system with data acquisition, processing, storage, and display functions.
