Description

Technical Field

[0001] The invention belongs to the technical field of coal mine hydrogeological monitoring, and relates to a coal mine hydrogeological monitoring method and system. Background Art

[0002] At present, the hydrogeological problems in coal mines can be roughly divided into the following aspects: 1) Insufficient water resource guarantee capacity for coal construction; 2) The threat of mine water hazards affects the safe production and service life of coal mines; 3) The water environment problems in mining areas are prominent.

[0003] Coal deposit hydrogeological exploration is a method to identify the hydrogeological conditions of coal mining areas. The main means and evaluation methods of hydrogeological exploration are: hydrogeological mapping, hydrogeological geophysical prospecting, hydrogeological drilling, hydrogeological testing and monitoring, geological analysis, water inrush coefficient method, water inflow prediction, etc. However, due to the unreasonable or incomplete use of means and evaluation methods, the exploration results are somewhat one-sided, mainly manifested in: 1) Insufficient understanding of the hydrogeological conditions of coal mining areas; 2) Long exploration cycle; 3) Large errors in exploration results; 4) Single evaluation starting point, without comprehensive evaluation combined with ecology and resources.

[0004] In the existing technology, the geophysical method combining electrical prospecting and seismic prospecting provides a fast and economical prospecting method for solving hydrogeological problems in coal mines. One method of geophysical prospecting in coal mining areas is to use electrical prospecting to study the occurrence of Ordovician limestone water and sandstone water in the survey area, combined with the structural results interpreted by seismic prospecting, to further explain the water conductivity of the structure and the thickness of the gland water barrier. The second method is to use the high-resolution three-dimensional seismic data body of the mining area combined with the existing drilling data to analyze and interpret the target layer structure of the mining area and establish a complete set of three-dimensional structural images. In recent years, underground advanced geophysical prospecting methods such as audio-frequency electric penetration detection technology, Rayleigh wave detection technology, and seismic trough wave detection technology have also gradually been applied in production. The isotope method can not only analyze the causes of groundwater formation, but also analyze its origin, burial, changes in quality and quantity, and other factors that form groundwater. Through data analysis and comparison, it can determine the proportion of the total recharge source of groundwater, the recharge source, the height of the recharge area, the level of recharge intensity, and the age of groundwater, the height of the recharge area, and the flow direction and velocity of groundwater. However, there is currently a lack of corresponding modeling technology for the creation of refined three-dimensional geological models containing faults, underground facilities, and some unfavorable geological bodies in the strata, and it is not possible to accurately detect the hydrogeological conditions of coal mines. Summary of the invention

[0050] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in detail below in conjunction with the accompanying drawings, wherein:

[0051] Figure 1 A flow chart of a method for coal mine hydrogeology monitoring provided in Embodiment 1 of the present invention;

[0052] Figure 2 A diagram of a coal mine hydrogeological monitoring system provided in Embodiment 2 of the present invention;

[0053] Figure 3 This is a schematic diagram of the structure of the coal mine hydrogeological monitoring equipment provided in Example 3 of the present invention. DETAILED DESCRIPTION

[0054] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the illustrations provided in the following embodiments only illustrate the basic concept of the present invention in a schematic manner, and the following embodiments and features in the embodiments can be combined with each other without conflict.

[0055] Embodiment 1:

[0056] This embodiment provides a coal mine hydrogeological monitoring method, such as Figure 1 As shown, the method specifically comprises the following steps:

[0057] S1: Collect the hydrogeological data of the coal mine to be tested, analyze the structural characteristics of the hydrogeological data, and determine the dynamic characteristics of the hydrogeological data corresponding to the structural characteristics.

[0058] Hydrogeological data include historical hydrogeological data, hydrogeological popular science materials, water quality testing reports, coal mine exploration hydrogeological engineering reports and their attached drawings, and hydrogeological supplementary survey reports and their attached tables.

[0059] S2: Select the appropriate remote sensing image type and analyze the remote sensing image.

[0060] It is understandable that, based on the data interpretation and identification, the hydrogeological data of the reservoir area in the study area are divided into surface DEM, strata, faults, profiles and geological boundaries; the relevant data in the original data such as the survey report, engineering geological map and geophysical data are generalized from the geotechnical engineering survey report and divided into surface topography, strata, faults, underground facilities and monitoring of groundwater level.

[0061] Step S2 specifically includes the following steps:

[0062] S21: Using electromagnetic radiation technology to enhance the brightness of the remote sensing image to obtain a first image.

[0063] S22: Correcting the damaged portion of the first image according to a geometric correction method to obtain a second image, specifically including:

[0064] Performing atmospheric correction and orthorectification processing on the first image collected by the optical remote sensing satellite;

[0065] The first image collected by the radar remote sensing satellite is orthorectified.

[0066] It should be noted that the remote sensing data are processed according to the product level of the acquired remote sensing data: the remote sensing images collected by optical remote sensing satellites are mainly subjected to atmospheric correction and orthorectification processing, and the remote sensing images collected by radar remote sensing satellites are subjected to orthorectification processing.

[0067] The present invention uses satellite remote sensing technology to detect hydrogeology, which can better analyze and calculate the location and data of groundwater resources. It can also analyze the information and images generated during the monitoring process to accurately find the location of groundwater in the coal mine, which can meet actual monitoring needs.

[0068] S23: Eliminate the resolution in the second image, where the resolution includes four items of resolution: spatial resolution, radiation resolution, spectrum resolution, and time resolution of illumination and the earth to surface objects, to obtain a resolved remote sensing image.

[0069] S3: Based on the analyzed remote sensing images and dynamic features, combined with the spectral characteristic curves of the objects of different image types, select the appropriate interpretation band, pre-process the interpretation band, and obtain the interpretation band result, which specifically includes the following steps:

[0070] S31: normalize and grayscale the image data in the interpreted band to obtain a grayscale image.

[0071] It can be understood that, in this step, preprocessing the image can improve the quality and clarity of the denoised image, making it easier to extract more accurate emotional features.

[0072] S32: Perform key point recognition based on the grayscale image to obtain a recognition image result.

[0073] It can be understood that in this step, a neural network is used to extract key points of the image in the interpretation band based on the grayscale image to obtain a recognition image result.

[0074] S33: Match the recognition image results, remote sensing images and dynamic features to obtain an interpretation band recognition table.

[0075] S34: Matching is performed using a collaborative filtering algorithm based on the interpretation band identification table to obtain a final interpretation band result.

[0076] It is understandable that the images in the present invention contain dynamic information such as geology and hydrology, and have clear features, which are easily affected by appearance factors such as background and lighting. Using them for matching can more effectively improve the robustness of the behavior recognition system. And using collaborative filtering algorithms for matching can improve the accuracy of the results.

[0077] It should be noted that the present invention applies satellite remote sensing technology to coal mine hydrogeological exploration, which can effectively avoid the occurrence of dangerous accidents. It can not only provide a good summary of the overall hydrogeological situation of the mining area, but also investigate and analyze the actual distribution of aquifers and internal geological structures in the mining area, thereby realizing the rational use of coal mines, allowing mining work to be carried out efficiently and safely, and providing protection for the life safety of coal mine workers.

[0078] S4: Based on the interpretation band results, a three-dimensional hydrogeological model is constructed, and the hydrogeological data of the coal mine to be tested is input into the three-dimensional hydrogeological model to obtain the hydrogeological monitoring results of the coal mine.

[0079] The constructed three-dimensional hydrological address model is actually a three-dimensional hydrological model. The results can be obtained by inputting hydrogeological data and other data into the model. Hydrogeological data can be added with multi-source data such as hydrogeological boreholes, hydrogeological maps, surface elevations, etc. as constraints to construct a hydrogeological three-dimensional structural model.

[0080] Data collection and analysis: First, it is necessary to collect geological data of the study area, including rock structure characteristics, elevations of interfaces between rock layers, dynamic characteristics of water levels in the reservoir area, etc.

[0081] Preprocessing and input: The collected geological data are preprocessed, including data cleaning, format conversion, etc., and then entered into the modeling software.

[0082] Multi-source data integration: The pre-processed data is integrated with the three-dimensional spatial data to achieve integrated display and build a refined three-dimensional hydrogeological model.

[0083] Dynamic exploration and model verification: dynamic exploration and verification of the constructed model; dynamic monitoring of groundwater level and mapping of groundwater flow field: through the three-dimensional hydrogeological model, dynamic monitoring of groundwater level in the study area is carried out, and a groundwater flow field model is generated to analyze the formation conditions, characteristics and dynamic laws of groundwater.

[0084] It can be understood that in this step, a three-dimensional hydrogeological model is constructed to facilitate the personnel to measure the coal mine hydrogeology better, more conveniently and accurately, and obtain monitoring results. If the monitoring result is greater than the threshold, the place where the hydrogeology has problems is found. If the monitoring result is less than the threshold, the observation continues and the data is recorded in the database.

[0085] The present invention provides a reasonable and reliable hydrogeological basis for coal mining; when mining coal resources, water is also regarded as a resource, and a comprehensive evaluation is conducted from the aspects of drainage, supply and environment, providing a technical basis for the sustainable development of coal mines.
