Abstract

The invention relates to the technical field of mine hydrogeological monitoring, in particular to a method for obtaining continuous parameters of an aquifer based on a superimposed drainage test. Themethod comprises the following steps: 1, implementing the superimposed drainage test in a research area; 2, establishing a numerical model of a research area and dividing a grid discrete model; 3, setting a random distribution function value of aquifer parameters; 4, selecting an applicable covariance function to describe the variation degree of the aquifer parameters; 5, iteratively calculating the continuous distribution of the aquifer parameters by using a water drainage chromatography method. The method is easy to operate and wide in applicability; compared with a traditional analysis method, the obtained hydrogeological parameters are more detailed and specific, the heterogeneity of the aquifer can be accurately described, the position and range of the water-rich abnormal area can beaccurately positioned, the mine water inrush disaster risk is effectively reduced, and comprehensive technical guarantee is provided for safe production of mining areas.

Description

technical field [0001] The invention relates to the technical field of mine hydrogeological monitoring, in particular to a method for obtaining continuous parameters of an aquifer based on superimposed water release tests. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] The spatial distribution characteristics of aquifer hydrogeological parameters have a great impact on mining work, and are the basis for analyzing the water-richness of aquifers in mining areas. The location and scope of the water-rich anomalous area directly restrict the layout of the shaft and roadway system and affect mine safety. Finding out the detailed information of the aquifer parameters can provi...
