摘要（英）：

The invention discloses an ultra-thick top coal thickness detection device based on an ultra-narrow pulse ultra-wideband radar technology, and belongs to the technical field of ultra-thick coal seam fully-mechanized mining. The ultra-thick top coal thickness detection device comprises a radar detection device, a telescopic device, a hydraulic support and a groove host machine, wherein the telescopic device is installed below a top beam of the hydraulic support through a hinge; the radar detection device is connected between the telescopic device and the hydraulic support; the output end of theradar detection device is connected with the input end of the groove host machine; and the groove host machine controls the top beam of the hydraulic support to adjust the height, namely, the radar detection device is adjusted to be always at an optimal detection position, and ultra-narrow pulse ultra-wideband signals are received and transmitted, so that accurate detection of the top coal thickness is achieved. The method has the advantages of strong penetrating capacity, high detection speed, high resolution and the like, the detection depth of the thickness of the top coal can reach 35m, and the detection precision is centimeter grade. The method is suitable for intelligent fully-mechanized mining of ultra-thick coal seams.
