Abstract: According to a specality of underground mine environment to cause problem ofthe limitaion to obtain mss information measured in underground mineand others a study was conducted on the present concerned compressed sensing theor - a new samping theory based on the signal sparityBased on mine inermet ofthings as studly object.the paper inroduced basic theory and key technolgy of the compressed sensing and analyzed advantages ofthe compressed sensing theory inaplcatin environment.Thecetcally the compressed sensing theory could mee application reqxuirements of mine intenet of thigs.Fmal ythe Matiab sinulaton sofware was applied to sparsity analysis compression and reconstruction ofthe gas concentration datacollctedfrom underground mine and the rsulis shoved that ofginaconcentration signal could be accurately recovered by compressed sensing technology.
