Description

Technical Field

[0001] The present invention relates to the field of measurement of the original ore quantity in salt lakes, and particularly to a method and device for measuring the ore quantity. Background Art

[0002] When the original ore in the salt lake is transported out, first, the brine in the ore pond is drained, then the original ore is formed into ridges, and then the original ore is transported to the ore pile for workshop production.

[0003] There are generally two methods for determining the ore quantity in the prior art. Method 1: The mined and transported ore quantity is calculated according to the vehicle volume measurement. The transportation list signed and recognized by both Party A and Party B is used as the settlement basis. The volume measurement of each vehicle is divided into two parts: (1) The volume measurement of the vehicle cargo compartment is calculated as: length × width × height = the actual volume of the vehicle cargo compartment; (2) The measurement of the ore above the vehicle cargo compartment: The ore is loaded until the cargo compartment is saturated and cannot be loaded anymore. The potassium ore above the vehicle cargo compartment is calculated according to the measured ore quantity of the protruding part on site (according to the triangular cross-sectional area × vehicle length); (3) The total volume = the actual volume of the cargo compartment + the part above the cargo compartment. Method 2: The mined and transported ore quantity is calculated according to the net weight measured by weighing. These methods not only have cumbersome measurement methods, consume a large amount of manpower and material resources, but also have large measurement errors. Summary of the Invention

[0056] The following will describe in detail the specific embodiments of the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for explaining and illustrating the embodiments of the present invention, and are not used to limit the embodiments of the present invention.

[0057] It should be noted that in the technical solution of this application, the acquisition, transmission, storage, use, processing, etc. of data all comply with the relevant regulations of laws and regulations. In the embodiments of this application, some industry - existing solutions such as certain software, components, models, etc. may be mentioned. They should be considered as exemplary, and their purpose is only to illustrate the feasibility in the implementation of the technical solution of this application, but it does not mean that the applicant has already or necessarily used this solution.

[0058] Figure 1 is a flowchart of a method for measuring ore quantity according to the present invention. As Figure 1 shown, the present invention discloses a method for measuring ore quantity, and the method includes:

[0059] Step S101 is to obtain the three - dimensional coordinate parameters of the target mining area and determine the conversion coordinate parameters according to the three - dimensional coordinate parameters.

[0060] According to a specific embodiment, the three - dimensional coordinate parameters include: X translation parameter, Y translation parameter, Z translation parameter, X rotation parameter, Y rotation parameter, Z rotation parameter, scale parameter;

[0061] The determining the conversion coordinate parameters according to the three - dimensional coordinate parameters includes:

[0062]

[0063] Among them, dx, dy, and dz are the X translation parameter, Y translation parameter, and Z translation parameter respectively, ω x 、ω y, ω z They are the X rotation parameter, Y rotation parameter, and Z rotation parameter respectively. m is the scale parameter. X1, Y1, and Z1 are the coordinates in the original coordinate system, and X2, Y2, and Z2 are the coordinates in the transformed coordinate system.

[0064] Specifically, before obtaining the three-dimensional coordinate parameters of the target mining area, it is necessary to clarify the coordinate system used for measurement, such as the 1980 Xi'an coordinate system, 93-degree central meridian (6-degree zone), and 1956 Huanghai elevation system. Conversion parameter name: Xi'an 80-93-56 (Chuan), and calculate or obtain the coordinate conversion parameters to unify the measurement results into the same coordinate framework.

[0065] This application uses the seven-parameter method to calculate the conversion parameters. The seven-parameter method is used for conversion between different three-dimensional space rectangular coordinate systems and requires calculating seven parameters, including three translation parameters (dx, dy, dz), three rotation parameters (ω x , ω y , ω z ), and one scale parameter (m). Usually, at least three known common points (points with known coordinates in both coordinate systems) are required. Substitute their coordinates into the above formula to obtain a linear equation system, and then solve the equation system by methods such as the least squares method to obtain the values of the seven parameters.

[0066] Step S102 is to obtain the intersection coordinates and elevation of the surface threshold area grid of the target mining area as the first parameter according to the conversion coordinate parameters, and determine the ore layer surface map before ore extraction in the target mining area according to the first parameter.

[0067] According to a specific implementation manner, the obtaining the intersection coordinates and elevation of the surface threshold area grid of the target mining area as the first parameter according to the conversion coordinate parameters, and determining the ore layer surface map before ore extraction in the target mining area according to the first parameter includes: measuring the intersection coordinates and elevation of the ore layer surface threshold grid as the first parameter according to the conversion coordinate parameters; displaying the first parameter in the threshold grid to obtain the ore layer surface map before ore extraction in the target mining area. The method for obtaining the ore layer surface threshold grid is RTK instrument measurement and / or remote sensing mapping. The threshold grid can be 50×50m, 100×100m, etc.

[0068] Specifically, calibrate the RTK surveying instrument through known control points. According to the conversion coordinate parameters, use the RTK surveying instrument to measure the intersection coordinates and elevations of the 50×50m grid points on the ore layer surface. The measured DAT data file cannot be directly called by the CASS mapping software. First, use the "Output of Survey Point Results" function in the "Engineering Star" file menu of the hand-held device to convert the DAT file into the data format of the CASS software. Then, connect the hand-held device to the computer with a data cable to import the converted data format into the computer. Open the previously drawn grid graph with the CASS software, and then use the "Display Elevation Points" function of the software to display the measured elevations of the ore layer surface in the graph, and draw the ore layer surface graph before ore extraction.

[0069] The RTK reference station frame of this application can be set at a relatively high position, with a wide view and far away from objects that strongly interfere with satellite signals, such as high-power radio transmitters and high-voltage transmission lines. The radio coverage range is 10 km. Select a location that is convenient for installing equipment and operation and can obtain the maximum effective data communication radius to set up the base station, radio, and antenna. Connect the data cable as required, and turn on the power of the base station, radio, and hand-held device. Connect the base station through the Bluetooth of the hand-held device. When the number of received satellites reaches 5 or more, start the radio. After the radio indicator shows that a communication signal is sent, start the mobile station. Connect the mobile station through the Bluetooth of the hand-held device. When the number of received satellites reaches 6 or more and the hand-held device shows a fixed solution state, calibrate the base station coordinates with known control point 1 and check the coordinate accuracy with known control point 2. Establish the project engineering name, file name, and set the coordinate conversion parameters. After the parameter setting is completed, start the RTK field data collection. The data collected in the field is stored in the hand-held device in the form of a DAT data file.

[0070] Step S103 is to select a reference point on the top surface of the dam in the target mining area as the filling elevation of the dam surface, and determine the first filling volume from the ore layer surface to the dam surface according to the filling elevation and the ore layer surface graph.

[0071] According to a specific implementation manner, the determining the first filling volume from the ore layer surface to the dam surface according to the filling elevation and the ore layer surface graph includes: calculating the first filling volume from the ore layer surface to the dam surface by using the DTM method for the filling elevation and the ore layer surface graph.

[0072] As Figure 2 shown, take a reference point B on the top surface of the dam to measure the elevation as the filling elevation of the dam surface, and use the DTM method to calculate the filling volume from the ore layer surface to the dam surface as V2.

[0073] Step S104 is to measure the intersection coordinates and elevations of the grid points in the threshold area of the ore pool bottom plate after the original ore is mined and transported as the second parameter, and determine the ore pool bottom plate surface graph according to the second parameter.

[0074] According to a specific embodiment, based on the converted coordinate parameters, the intersection coordinates and elevations of the threshold grid on the surface of the ore extraction layer after the extraction and transportation of the raw ore are measured as the second parameter; the second parameter is displayed in the threshold grid to obtain the curved surface map of the bottom of the ore pool. The method for obtaining the threshold grid on the surface of the ore layer is RTK instrument measurement and / or remote sensing mapping. The curved surface map of the bottom of the ore pool can be replaced by unmanned aerial vehicle (UAV) remote sensing mapping, and UAV remote sensing has the characteristics of low mapping cost, flexible and fast operation mode, etc.

[0075] Specifically, after the extraction and transportation of the raw ore in the ore pool are completed, the RTK measurement instrument is calibrated and detected through known control points, and the intersection coordinates and elevations of the 50×50m grid on the bottom of the ore pool are measured by the instrument, and the curved surface map of the bottom of the ore pool is drawn in the software. Using the RTK technology for topographic mapping does not require the layout of encrypted control points, and there is no need for intervisibility between points. Compared with the traditional measurement method, this method can greatly shorten the measurement time and improve work efficiency. Especially in large-area topographic surveys or ore volume calculations in emergency situations, the advantages are more obvious.

[0076] Only one person is required to operate one rover station of the present invention, and one person draws a sketch. The base station can run automatically after being set up. The coordinate information of the measurement point can be obtained in real time without waiting for post-processing, which greatly improves work efficiency.

[0077] Step S105 is to use the elevation of the reference point as the filling elevation of the dam surface, and determine the second filling volume from the curved surface of the bottom of the ore pool to the dam surface according to the filling elevation and the curved surface map of the bottom of the ore pool.

[0078] According to a specific embodiment, the determining the second filling volume from the curved surface of the bottom of the ore pool to the dam surface according to the filling elevation and the curved surface map of the bottom of the ore pool includes: using the DTM method to calculate the filling elevation and the curved surface map of the bottom of the ore pool to obtain the second filling volume from the curved surface of the bottom of the ore pool to the dam surface.

[0079] For example, using the elevation of the dam reference point B as the filling elevation of the dam surface, the filling volume from the curved surface of the bottom of the ore pool to the dam surface is calculated as V1.

[0080] Step S106 is to determine the volume of the raw ore in the target mining area according to the first filling volume and the second filling volume.

[0081] According to a specific embodiment, the determining the volume of the raw ore in the target mining area according to the first filling volume and the second filling volume includes: the volume of the raw ore = the second filling volume - the first filling volume.

[0082] Specifically, the volume V of the raw ore in the ore pool is the filling volume V1 from the bottom of the ore pool to the dam surface minus the filling volume V2 from the curved surface of the ore layer to the dam surface, that is, V = V1 - V2.

[0083] The measurement accuracy of this method can reach the centimeter level, and the point position accuracy is evenly distributed, without error accumulation like traditional measurements, so the results are more reliable. It can accurately measure the elevation and coordinate information of the terrain. This enables more accurate determination of the terrain undulations when calculating the ore volume, thereby improving the accuracy of volume calculation.

[0084] Moreover, the data results obtained by this application are convenient for storage, management, and sharing, achieving the purpose of multi-purpose measurement. This data can also be combined with computer software to realize automatic acquisition, processing, and analysis of measurement data. The surveyors only need to perform simple operations in the field to transmit the measurement data to the computer, and the software automatically calculates the volume; this can not only improve work efficiency but also reduce human errors and improve the accuracy of ore volume calculation. After the measurement data of the ore pool floor is saved, it can provide a basis for subsequent ore cultivation and ore piling, facilitating the estimation of ore volume, thus combining theory with actual measurement and enhancing the accuracy of ore cultivation. This method can also perform measurements under various weather conditions, unaffected by day or night. During ore extraction, it is not affected by external factors such as water accumulation.

[0085] On the other hand, the present invention also proposes a device for measuring ore volume, as Figure 3 shown. The device 100 for this ore volume measurement method includes:
