Abstract: The principle of spectral remote sensing detection technology is introduced, and the design scheme based on spectral remote sensing detection technology is discussed in this paper; through the study of spectral remote sensing technique, based on spectral absorption telemetry and scattering of perception, using the principle of the interaction between photon and molecule, harmful gases and dust material concentration of perceptual information are proven; detection signal is extracted from the optical signal containing concentration values, which provides a kind of advanced air pollution monitoring technology for the remediation of coal mine environment.
