Abstract

The invention discloses a hierarchical-fuzzy-analysis-based method for determining limestone water inrush evaluation of a coal seam floor. The method comprises: summarizing main controlling factors affecting limestone water inrush and establishing a hierarchical structure model; on the basis of the hierarchical structure model, respectively establishing a factor set and a weight set; according tomining experience combined with production practices, establishing an evaluation level set; determining membership degrees of all influencing factor evaluation indexes and fuzzy relationship matrixes;and evaluating limestone water inrush comprehensively by combining the evaluation level set according to a fuzzy hierarchical analytic result. On the basis of the fuzzy analytic hierarchy theory, thelimestone water inrush is evaluated qualitatively and quantitatively by combing the mining experience and production practices; and the evaluation result is reasonable and reliable and has certain novelty. Moreover, the operation is simple and the method is easy to implement actually. Therefore, a novel method and idea are provided for evaluating the floor limestone water inrush.

Description

technical field [0001] The invention relates to the technical field of preventing limestone water inrush from coal seam floors, in particular to an evaluation method for limestone water inrush performance on coal seam floor based on fuzzy hierarchical analysis. Background technique [0002] Water inrush from coal seam floor is an urgent practical problem to be solved in coal mine safety production. The occurrence of water inrush accidents not only seriously restricts the mining of coal resources, but also seriously affects the economic benefits of mine mining. The water inrush of the floor limestone will often cause major safety hazards to the excavation of the roadway and the recovery of the coal seam. At present, there are mainly methods for determining the weight of water inrush factors in floor limestone, such as vulnerability index method and analytic hierarchy process. However, most of these theories are cumbersome, requiring many parameters and complicated steps. A...
