Ground temperature of Qianjiaying Mine closed to 30 degrees and temperature of west wing from -600 to -850 level belonged to high temperature zone. West Wing coal water and Ordovician limestone water, as well as West Wing of high temperature and ingress of Ordovician limestone water had a certain kind of relation. At the bottom of the Ordovician limestone, hot water entered into roadway would form a stable heat source. Reflecting two aspects of water disaster: one was each containing water layer closely contactiing with bottom water in Ordovician limestone and the other was excessive water temperature, the connection channel between coal water and Ordovician limestone water were found out. Causes of high geotemperature anomaly were analyzed in Qianjiaying Mine and corresponding measures for prevention and control of water disasters were formulated.
