On the Prediction Ways of the Height of Transmissive Fissure Zones

As the devoloping of mining technology and in order to reduce the size of waterproof pillars and exploit abundant underwater coal resource,a lot of researches on the transmissive fissure zones and installation of waterproof pillars underwater coal beds have been made.The height of transmissive fissure is a major parameter for the designing the sizo of waterproof coal pillar.So,it is an important content of waterproof measures in underwater coal mine.The paper introduces the detalied study situation and development of prediction methods at home and abroad and puts forward a comprehensive method of prediction and evaluation based on the geologic environment and mechanical setting of covered rock bodies and their numerical simulation.
