Research and practice since the last century have shown that my country has a more comprehensive understanding of the water-conducting fracture zone of the overlying rock. The development height of the water-conducting fissure zone has important research significance in mine safety production, coal mine water control, mine water-preserving coal mining, goaf and upper corner gas control of return airway, coal and gas mining, coal mining under water, etc. This article reviews and categorizes previous studies, focuses on various prediction, simulation, and actual measurement methods for the height of the water-conducting fractured zone, and introduces the current new methods for measuring the height of the water-conducting fractured zone, indicating that the current detection methods have been It has developed in the direction of combining multiple methods, drilling and geophysical prospecting, and ground and downhole. The problems and development trends in the study of water-conducting fracture zones are also proposed.
