description The utility model relates to the technical field of gas diffusion initial velocity measuring devices, and discloses a high-precision full-automatic gas diffusion initial velocity measuring device which comprises a test box used for detecting a coal sample, and an installation groove used for installing a coal sample tank is formed in the front side of the test box. The coal sample tank is detachably installed in the installation groove through a fixing frame, a sealing cover is fixed to the upper end of the fixing frame, and a hydraulic cylinder used for tightly jacking the coal sample tank is fixed to the lower portion of the fixing frame. According to the high-precision full-automatic gas diffusion initial velocity measuring device, by arranging a compression spring, a hydraulic cylinder can be more stable in the process of driving a coal sample tank to ascend, the coal sample tank is prevented from shaking during ascending, meanwhile, the coal sample tank is driven by the hydraulic cylinder to ascend and i
