Abstract

The invention discloses a method for evaluating the water content of faults based on hierarchical analysis, which includes: summarizing the main factors affecting the water content of faults, and establishing a hierarchical structure model; relying on the hierarchical structure model, respectively establishing factor sets and weight sets; combining mining experience with production In practice, establish an evaluation level set; determine the membership degree and fuzzy relationship matrix of the evaluation indicators of each influencing factor; combine the evaluation level set with the results of the AHP to comprehensively evaluate the water content of the fault. Based on the AHP theory, combined with mining experience and production practice, the present invention evaluates the water content of faults qualitatively and quantitatively. Evaluation provides a new method and idea.

Description

technical field [0001] The invention relates to the technical field of preventing water inrush by coal-measure pressure-bearing faults, in particular to a method for evaluating the water content of faults based on analytic hierarchy process. Background technique [0002] Due to the influence of tectonic movement, near the fault with a large drop in the coalfield, the mineable coal seam can be in direct contact with the rock on the uplift wall of the fault, so that the confined water can create a hydraulic connection with the aquifer of the roof and floor of the coal seam through the fault, thus causing coal mine outburst. water. Therefore, in coal mine production, investigating the water content of faults with large drop is an important hydrogeological work content. At present, the methods for evaluating the water content of faults mainly include controlled source audio frequency magnetotelluric method, transient electromagnetic method, pumping and water injection test meth...
