Embodiment 1

[0041] Such as Figure 1-5 As shown, a method for identifying water inrush sources in complex hydrogeological mines in this embodiment includes the following steps:

[0042] S1. First, according to the structural distribution and hydrogeological conditions, combined with the mine excavation engineering layout, the mine field is divided into 5 areas; the suburban mining area is divided into a horizontal east wing, a horizontal north wing, a horizontal northwest wing, a second horizontal west wing and Two levels of five subdivisions on the south wing. According to the hydrochemical data of the water samples in each district, select the index that can distinguish the main water inrush aquifer in each district as the characteristic identification index, and also determine its threshold value, and identify the identification relationship when identifying the water source; the identification index standard is the identification index The content changes in the water samples of each...

Embodiment 2

[0054] Such as Image 6 : present embodiment also discloses a complex hydrogeological mine water inrush water source identification system, the system includes the following modules:

[0055] Geological division module: First, according to the structural distribution and hydrogeological conditions, combined with the mine excavation engineering layout, the mine field is divided into 5 areas;

[0056] Modeling module: use the collected and collected data of water samples as modeling samples;

[0057] Characteristic module: For a water sample of a single aquifer to be judged in a certain area of ​​the mining area, data inspection is carried out to determine the characteristic indicators and limit values ​​of the water sample;

[0058] Preliminary water source identification module: based on effective feature identification indicators, threshold values ​​and Fisher and Bayes identification methods, a partition-comprehensive identification model is established;

[0059] Test modu...

Abstract

The invention discloses a gushing water source identification method for a mine of complex hydrogeology. The method comprises the following steps that S1) a mine field is divided into 5 areas according to structural distribution and hydrogeology conditions as well as arrangement of mine digging engineering; S2) collected water sample data serves as a modeling sample; S3) data of a to-be-identified single aquifer water sample of certain area of the mining area is tested to determine a characteristic index and threshold value of the water sample; S4) a partitioning-integrated identification model is established according to effective characteristic recognition index and boundary value, and a Fisher and Bayers identification method; S5) the accuracy of the partitioning-integrated identification model is tested via a back substitution estimation method; and S6) and a water sample identification index to be determined is determined, and a water source is identified via the partitioning-integrated identification model. The invention also discloses a gushing water source identification system for the mine of complex hydrogeology. The method and system are suitable for identifying a gushing water source with the relatively complex hydrology geology condition.

Description

technical field [0001] The invention relates to the field of water source identification, in particular to a method and system for identifying water inrush sources in complex hydrogeological mines. Background technique [0002] Water damage is one of the main disasters affecting coal mine production and safety. The hydrogeological conditions of my country's coal deposits are complex and diverse, and mine water disasters are frequent, which has always been one of the important factors restricting the development of my country's coal production. The loss of life and property caused by coal mine floods to the country and people is huge. The identification of mine water filling source is the basis of water prevention and control work, and it can provide a basis for formulating reasonable and effective water prevention and control measures (drainage, pressure reduction and water blocking). [0003] At present, the main methods for mine water source identification include water ...
