Embodiment

[0057] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0058] first part:

[0059] The present invention is a method for discriminating water inrush sources based on a combined weight set pair analysis model, the method comprising:

[0060] Step A, collect the hydrochemical data of each aquifer and the hydrochemical data of the water samples to be evaluated;

[0061] Step B, determining the evaluation index of the water inrush water source discrimination model;

[0062] Step C, determining the combination weight of each evaluation index;

[0063] Step D, constructing a discriminant model based on the combined weight set pair analysis model;

[0064] Step E, comparing the result of identifying and verifying the sample with the actual result through the discriminant model;

[0065] Step F, predicting the water sample to be evaluated according to the satisfactory discriminant model.

Abstract

The invention relates to a water inrush source discrimination method, belongs to the technical field of coal mines, and particularly relates to a coal mine water inrush source discrimination method. The method comprises: combining a combination weight and improved set pair analysis; establishing a combined weight set pair analysis model; using the objective weight of entropy weight calculation and the subjective linear combination of improved analytic hierarchy process calculation as the combination weight. The problems that recognition factor weight calculation is inaccurate and calculation is difficult are solved. The problem that the membership degree of the water inrush source is difficult to determine is solved through the set pair model, and the recognition accuracy of the water inrush source is improved through the water inrush source recognition method.

Description

technical field [0001] The invention relates to a method and a system for discriminating a water inrush source, belonging to the technical field of coal mines, in particular to a method and a system for discriminating a water inrush source in a coal mine. Background technique [0002] The safe and efficient mining of coal resources is fundamental to my country's economic development. In order to prevent and reduce the occurrence of water inrush accidents, it is necessary to carry out water inrush forecasting. Among them, quickly and accurately identifying the source of mine water inrush is one of the basic tasks of mine water inrush forecasting. [0003] The identification of mine water inrush sources usually uses methods such as groundwater chemistry, isotope, water temperature, and water level dynamic observation. Groundwater chemistry can reflect the essential characteristics of groundwater, and can identify water sources accurately, quickly, and economically. be widely ...
