Acquisition of mine water inrush rules based on Rough Set Theory

Taking a subset of water inrush samples as example, some water inrush rules corresponding to the subset have been acquired, through such procedures as data pretreatment of initial decision-making information table, attribute reduction, value reduction and rules generation. These rules preferably cover the water inrush information included potentially in the subset,and have equivalent effectiveness for classifying and making decision compared with the subset itself.
