KJ428 Distributed laser fire monitoring system for coal mine

Product introduction

KJ428 Distributed laser fire monitoring system for coal mine is dedicated to solve the defects of the existing bundle pipe system in coal mining goaf on fire monitoring early warning such as slow response and unprocurable location. On the analysis basis of fire cause and occurrence process in mining goaf, utilizing of optical fiber sensing technique in the underground mining face realizes distributed continuously temperature measurement in long distance in goaf, and adopting of WMAS wavelength modulation absorption spectral technique achieves concentration’s successively monitoring of CH4, CO, C2H2, CO2 and O2 in goaf, finally all collected data will be transferred back to the ground in real-time through optical fiber ring network, taking advantage of goaf spontaneous combustion model, to attain purposes of monitoring, early warning and fireproof effect evaluation.
