description The utility model provides a hydraulic flexible pipe pushing device of an underground coal mine directional long drill hole peeping instrument, which relates to the field of underground coal mine directional drill hole peeping and comprises a drill hole peeping instrument, a pressure-resistant expansion hose, a gear pushing pump and a signal transmission cable. The problems that in the prior art, pushing of a pushing rod cannot be achieved, directional drilling curvature changes are difficult to adapt, peeping is discontinuous, efficiency is low, and labor intensity is high are solved. The pressure-resistant hose is expanded through hydraulic power to be matched with the gear pushing pump to push the drilling peeping instrument, compared with traditional pushing of a pushing rod in rigid connection, the drilling peeping instrument can adapt to directional drilling curvature changes, in addition, high-pressure water in the pressure-resistant hose can effectively keep the wall of a drilled hole stable, and dril
