Dimensionless analysis was applied to correctly evaluate the order of the factors affecting water -inrush from coal floor. In the evaluation of water -inrush from coal floor, many factors need to be considered. Thus, to correctly evaluate the order of the factors affecting water -inrush from coal floor is very important, which is the key to reasonable evaluation of water -inrush from coal floor. Based...
Based on systematic collection of the hydrogeological data of coal mine, we analyzed the factors affecting water inrush from coal floor and determined the major factors. We used the fuzzy clustering method to evaluate the water inrush risk from coal floor in order to solve the evaluating limitation of water inrush risk from coal floor by the water inrush coefficient method. The fuzzy clustering method...
