With continued reference to FIG. 2, a flow 200 of one embodiment of a method for predicting a target area of a rare earth mineral resource in coal in accordance with the present invention is shown. The method for predicting the target area of the rare earth mineral resources in the coal comprises the following steps:
step 201, obtaining sample collection information of coal samples in an area to be predicted and sample rare earth content values in the coal samples, wherein the sample collection information comprises sample collection coordinates and sample coal seam numbers.
In this embodiment, the sample rare earth content value represents the content of each rare earth element in the coal sample, and may be, for example, the sum of the contents of each rare earth element in the coal sample.
In practice, a researcher can determine sampling points in a region to be predicted by adopting a diagonal sampling strategy or a quincunx sampling strategy, then respectively collect coal samples at different depths of each sampling point, number each coal sample, record the collection coordinate (such as a Global Positioning System (GPS) coordinate) and the collection depth of each coal sample, and then determine the sample coal seam number of each coal sample according to the collection depth, so that the sample collection information of each coal sample can be obtained. And then, performing element analysis on each coal sample to determine the sum of the content of each rare earth element in the coal sample, thereby obtaining the rare earth content value of each coal sample.
As an example, the executing body may be a terminal device shown in fig. 1, and a researcher may store the sample collection information and the sample rare earth content value of each coal sample in the terminal device, and then the terminal device executes the subsequent steps. The execution main body can also be a server shown in fig. 1, and the server can obtain the sample collection information and the sample rare earth content value of each coal sample from the terminal equipment through the network so as to execute the subsequent steps.
In some optional implementation manners of this embodiment, the coal sample includes coal in the mineable coal seam, gangue and coal seam roof and floor, organic shale, and associated mineral production occurrence stratum rock, so that diversity of components in the coal sample can be improved, and improvement of representativeness of the coal sample is facilitated.
Furthermore, the sample collection information also comprises an image and description information of the coal sample, and the description information can be description information of the environment of the collection place, and can also be appearance information of the coal sample, such as hardness, flexibility or gloss, and the characteristic dimension of the coal sample can be expanded.
And step 202, searching a spatial database of the rare earth elements in the coal based on the sample acquisition information.
The method comprises the steps that a spatial database of the rare earth elements in the coal is constructed on the basis of coal quality basic data of typical coal samples in a preset region, wherein the coal quality basic data comprise acquisition information and rare earth content values of the typical coal samples.
In this example, a typical coal sample represents a coal sample having a rare earth content meeting the mineralization standard. The spatial database of the rare earth elements in the coal may include coal quality basic data of typical coal samples at different collection times in a preset region (for example, the region may be a country or an administrative region), and the typical coal samples may be identified by numbers, where each number corresponds to a piece of coal quality basic data. For example, a relational database such as Oracle or MySQL may be employed.
As an example, the spatial database of the rare earth elements in the coal may be stored in a cloud server, the execution main body may input the sample collection information as a search condition into the cloud server through a service port, perform a search operation by the cloud server, and receive a search result returned by the cloud server.
It is understood that the spatial database of the rare earth elements in the coal may also be stored in the local space of the execution body, which is not limited by the present invention.
In some optional implementations of this embodiment, the coal quality basic data may further include the following information of the coal sample: location information, for example, may include administrative areas, mine areas, and fields where the coordinates were acquired; geological information, for example, may include various types of test indicators, such as coal seam thickness, coal age, and coal novelty; the content of various components and elements in the coal sample; physical properties of the coal sample, for example, may include density, ignition point, and the like; the chemical properties of the coal sample may include, for example, ash fusion characteristics calorific value, and the like.
And step 203, if the reference typical coal sample matched with the sample acquisition information exists in the spatial database of the rare earth elements in the coal, taking the rare earth content value of the reference typical coal sample as a reference value.
The reference typical coal sample meets the following conditions: the preset well field range or the preset mining area range represented by the collection information of the reference typical coal sample is the same as the preset well field range or the preset mining area range where the sample collection coordinate is located, and the difference value between the coal seam number in the collection information of the reference typical coal sample and the sample coal seam number is smaller than a first preset threshold value.
In the present embodiment, the preset field area or the preset mining area is a field area and a mining area divided according to the national coal geological survey. The geographical positions of the reference typical coal sample and the coal sample in step 201 are similar, and the geological environments of the reference typical coal sample and the coal sample are similar to the mining conditions, so that the rare earth content of the reference typical coal sample can be used as a reference value to predict whether the position of the coal sample has the mining conditions.
As an example, the execution main body may use the sample collection coordinates in the sample collection information as search conditions, search a typical coal sample located in a preset wellsite range or a preset mining area range where the sample collection coordinates are located from a spatial database of rare earth elements in coal, then use the sample coal seam number and a first preset threshold as screening conditions, filter out a typical coal sample whose coal seam number difference is not less than the first preset threshold, and obtain the remaining typical coal sample as a reference typical coal sample. Then, extracting the rare earth content value of the reference typical coal sample from the coal quality basic data corresponding to the reference typical coal sample as a reference value.
And 204, inputting the sample acquisition coordinates into a pre-constructed coal rare earth element mining area model if the rare earth content value of the sample is not less than the minimum value of the reference values.
The model of the coal rare earth element mining area comprises a mining area predicted based on coal-series mineral data and coal field geological data.
In this embodiment, the value of the rare earth content of the sample is not less than the minimum value of the reference values, which indicates that the region where the coal sample is located in step 201 has the basic condition of rare earth mineralization, and further analysis and prediction can be performed. The model of the mining area of the rare earth elements in the coal can represent the general rule of the distribution of the rare earth mineral resources, and correspondingly, the mining area can represent the area with higher probability of the rare earth mineral resources.
With further reference to fig. 3, fig. 3 illustrates the mineralization zones in the rare earth element mineralization zone model in the coal in an embodiment of the method for predicting a rare earth mineral resource target zone in the coal of fig. 2. As shown in fig. 3, the model of the rare earth element mining area in coal can be in the form of an image, and the mining area zone predicted based on the coal-based mineral data and the geological data of the coal field is marked in the image.
In some optional implementations of this embodiment, the method further includes: and if the sample rare earth content values of all the coal samples in the area to be predicted are smaller than the minimum value in the reference values, determining that the target area of the rare earth mineral resources does not exist in the area to be predicted.
In this implementation manner, the fact that the sample rare earth content value of the coal sample is smaller than the minimum value in the reference values indicates that the position of the coal sample in step 201 does not have the basic condition of rare earth mineralization, and it can be determined that the target region of the rare earth mineral resource does not exist in the position of the coal sample. And if the sample rare earth content values of all coal samples in the area to be predicted are smaller than the minimum value in the reference values, determining that the target area of the rare earth mineral resource does not exist in the area to be detected.
And step 205, if the acquisition range represented by the sample acquisition coordinates and the mining area zone have an overlapping area, predicting the target area of the rare earth mineral resources in the area to be predicted based on the rare earth content value of the sample, the sample acquisition coordinates and the coal quality basic data of a typical coal sample in the overlapping area.
In this embodiment, the collection range represented by the sample collection coordinates may be determined according to the number of sampling points and the interval between adjacent sampling points. The overlapping area of the collection range and the mineralization zone represented by the sample collection coordinates represents an area with a high probability of rare earth mineral resources.
In an example of the constraint, the execution subject may search a rare earth element spatial database for a typical coal sample with a sampling point located in an overlapping region, then mark the acquisition coordinates of the searched typical coal sample and the sample acquisition coordinates in the overlapping region, and determine an overlapping portion of a region surrounded by the acquisition coordinates of the typical coal sample with the highest rare earth content value and the sample acquisition coordinates and the region to be detected as a target region of the rare earth mineral resource in the region to be predicted.
In some optional implementation manners of the embodiment, if there is no overlapping area between the collection range represented by the sample collection coordinate and the mining zone, repeatedly sampling for many times in the collection range represented by the collection coordinate, and measuring the rare earth content value in the coal sample obtained by repeatedly sampling for many times; and if the difference value between the rare earth content value in the coal sample obtained by repeated sampling for multiple times and the rare earth content value of the sample is smaller than a second preset threshold value, updating the rare earth element spatial database and the coal rare earth element mining area model based on the sample acquisition information and the rare earth content value of the sample.
In this implementation manner, the difference between the rare earth content value in the coal sample obtained by repeated sampling for multiple times and the rare earth content value of the sample is smaller than the second preset threshold value, which indicates that the coal sample in step 201 can represent the overall characteristics of the coal in the area, and at this time, the collected data of the coal sample can be imported into the rare earth element spatial database to enrich the data amount in the rare earth element spatial database, and the mineralization zone in the coal rare earth element mineralization zone model is corrected according to the sample collection information, so as to improve the precision of the mineralization zone in the coal rare earth element mineralization zone model, and further improve the accuracy of predicting the target area of the rare earth mineral resource in the coal.
If the difference between the rare earth content value in the coal sample obtained by repeated sampling for multiple times and the rare earth content value of the sample is not less than the second preset threshold, it indicates that the coal sample in step 201 is not enough to characterize the overall characteristics of the coal in the area, and at this time, if the collected data of the coal sample is imported into the rare earth element spatial database, noise data may be introduced into the rare earth element spatial database, thereby affecting the accuracy of the data in the rare earth element spatial database.
According to the method for predicting the target area of the rare earth mineral resources in the coal, provided by the embodiment of the invention, a spatial database of rare earth elements in the coal is retrieved based on the sample acquisition information of coal samples in the area to be predicted; if a reference typical coal sample matched with the sample acquisition information exists in the spatial database of the rare earth elements in the coal, taking the rare earth content value of the reference typical coal sample as a reference value; if the rare earth content value of the sample is not less than the minimum value in the reference values, inputting the sample acquisition coordinates into a pre-constructed coal rare earth element mining area model; if the acquisition range represented by the sample acquisition coordinates and the mining area zone have an overlapping area, predicting the target area of the rare earth mineral resources in the area to be predicted based on the rare earth content value of the sample, the acquisition coordinates and the coal quality basic data of a typical coal sample in the overlapping area. The difficulty of predicting the target area of the rare earth mineral resources in the coal and the dependence on the professional experience of researchers are reduced, and the efficiency and the accuracy of predicting the target area of the rare earth mineral resources in the coal are improved.
With further reference to FIG. 4, step 205 in the above-described embodiment may also employ the flow 400 shown in FIG. 4. The process 400 includes the following steps:
step 401, retrieving basic coal quality data of typical coal samples collected in the overlapping region from the rare earth element spatial database.
As an example, the execution subject may retrieve coal quality basic data of typical coal samples collected in the overlap region from the rare earth element spatial database using the longitude range and the latitude range of the overlap region as retrieval conditions.
Step 402, generating a rare earth content element contour map based on the rare earth content value of the sample, the collection coordinates and the coal quality basic data of the typical coal sample in the overlapping area.
And 403, determining the target area of the rare earth mineral resource from the contour map of the rare earth content element based on a preset prediction threshold.
In this embodiment, the prediction threshold is not greater than the sample rare earth content value. The prediction threshold can be set according to empirical data, and it can be understood that the higher the prediction threshold is, the smaller the predicted range of the target area of the rare earth mineral resource is, the larger the proportion of the distribution range of the rare earth mineral in the corresponding target area of the rare earth mineral resource is and the higher the content of the rare earth element is. The lower the prediction threshold value is, the larger the range of the target area of the predicted rare earth mineral resource is, the smaller the proportion of the distribution range of the rare earth mineral in the target area of the rare earth mineral resource is, and the higher the content of the rare earth element is. ,
as can be seen from fig. 4, the process 400 of the method for predicting the target area of the rare earth mineral resource in coal in this embodiment represents a step of drawing a contour map of rare earth content elements based on the rare earth content value of the sample, the collection coordinates, and the coal quality basic data of a typical coal sample in the overlap area, and using the predicted target area of the rare earth mineral resource, the efficiency and accuracy of predicting the target area of the rare earth mineral resource in coal can be further improved.
Referring next to fig. 5, a flow 500 of constructing a spatial database of rare earth elements in one embodiment of a method for predicting a target area of a rare earth mineral resource in coal is shown. The process 500 includes the following steps:
and 501, acquiring the acquisition information and the coal quality test result of the historical coal sample in the preset area.
In this embodiment, the collected information includes collected coordinates and a coal seam number, and may further include an image and description information. The coal quality test result can comprise the content of various components and elements in the coal sample, and can also comprise position information, geological information, physical properties, chemical properties and the like of the coal sample. As an example, the collected information and coal quality test results of all historical coal samples nationwide may be obtained.
Step 502, extracting the rare earth content value of each historical coal sample from the coal quality test result.
Step 503, if the rare earth content value of the historical coal sample is larger than the preset rare earth content threshold value, determining the historical coal sample as a typical coal sample.
In this embodiment, a rare earth content threshold may be preset according to experience data of rare earth mineralization, the rare earth content being greater than the rare earth content threshold indicates that basic conditions of rare earth mineralization are met, and the rare earth content being not greater than the rare earth content threshold indicates that basic conditions of rare earth mineralization are not met, so that historical coal samples without basic conditions of rare earth mineralization may be filtered out, so as to avoid introducing noise data into a rare earth element spatial database, thereby affecting accuracy of data.
And step 504, combining the collected information of the typical coal sample and the rare earth content value into coal quality basic data of the typical coal sample.
And 505, constructing a rare earth element spatial database based on the corresponding relation between the coal quality basic data and the typical coal sample.
In a specific example, the execution subject may adopt MySQL, and the coal quality basic data is imported into MySQL based on a corresponding relationship between the coal quality basic data and a typical coal sample to obtain a rare earth element spatial database.
In an optional implementation manner of this embodiment, the method further includes: if the reference typical coal sample matched with the sample acquisition information does not exist in the coal rare earth element spatial database, and the rare earth content value of the sample is greater than the rare earth content threshold value, executing the following steps: repeatedly sampling for many times within the collection range represented by the collection coordinates, and measuring the rare earth content value in the coal sample obtained by repeated sampling for many times; and if the difference value between the rare earth content value in the coal sample obtained by repeated sampling for multiple times and the rare earth content value of the sample is smaller than a second preset threshold value, updating the rare earth element spatial database based on the sample acquisition information and the rare earth content value of the sample.
In this implementation manner, by comparing the coal sample obtained in step 201 with the coal sample obtained by repeated sampling, it can be determined whether the coal sample obtained in step 201 can represent the overall characteristics of coal in the area to be predicted, and if the coal sample obtained in step 201 can represent the overall characteristics of coal in the area to be predicted, the sample acquisition information and the sample rare earth content value are introduced into the rare earth element spatial database, so that on one hand, the data amount in the rare earth element spatial database can be enriched, and then, the accuracy of the target area of the rare earth mineral resource in coal can be predicted, and on the other hand, the introduction of noise data can be avoided, and the accuracy of data in the rare earth element spatial database can be affected.
As can be seen from fig. 5, the process 500 of the method for predicting the target area of the rare earth mineral resource in coal in the embodiment represents a step of constructing a rare earth element spatial database based on data of historical coal samples, and may integrate data of the historical coal samples with reference values into the database, and may retrieve a reference typical matched with the data according to the collected information of the coal samples, so as to improve the comparison efficiency between the collected data of the coal samples and the typical coal sample data.
