Zusammenfassung: | The invention relates to the technical field of mine geophysical prospecting, in particular to a coal seam spacing explosion-proof pulse radar detection method for upper protective layer mining, which comprises the following steps of: S1, arranging measuring points on a roadway bottom plate of an upper protective layer; s2, setting an anti-explosion pulse radar at a measuring point, and collecting radar data; s3, performing time zero correction on the radar data; s4, performing noise suppression and gain processing on the radar data to obtain a time domain reflection radar profile with a high signal-to-noise ratio; s5, calibrating the radar wave speed according to the drilling data, and obtaining a depth domain reflection radar profile through time-depth conversion; s6, identifying a reflection event of a top interface of the underlying protected coal seam on the depth domain reflection radar profile, and performing horizon tracking; and S7, extracting the depth value of the layer position of the coal seam to |
