Basic types of mine water disasters and classification of dynamic evolution types

Type classification of mine water disasters is the basic of mine water control. Therefore, it is necessary to make further classification on mine water disasters for the development of mine water control techniques. On the basis of summarizing the previous types of mine water disasters, the basic types of water disasters are classified by double-factor and coded in this paper. According to the evolution of water source and water passage, we proposed a classification method based on dynamic evolution and specific classification is carried out.
