[0047] In this embodiment, a coal rock identification sensor performance test method is provided. Figure 4 As shown, the following steps are included:

[0048] Step 1: Fix the coal-rock identification sensor on the mounting bracket of the motion module 2, and manually adjust the distance between the coal-rock identification sensor and the coal seam up and down through the mounting bracket;

[0049] Step 2: A position (X-axis coordinate, Y-axis coordinate) is given through the visual touch screen 1, and the motion module 2 drives the coal-rock identification sensor to the given position to identify the coal-rock structure at the given position.

[0050] Step 3: Control the motion module 2 to move at a uniform speed to identify the coal-rock structure at all positions; a speed (X-axis speed and Y-axis speed) is given by the visual touch screen 1, and the motion module 2 drives the coal-rock identification sensor to perform fixed-point circular motion, that is, to perform reciprocating simulated motion on the horizontal X-axis guide rail and the horizontal Y-axis guide rail of the motion simulation unit to identify the coal-rock structure at all positions;

[0051] There are three major interfaces in the coal-rock mass, namely the direct wave interface, the air-coal interface and the coal-rock interface. The identification of the three major interfaces is a prerequisite for positioning. Only by designing corresponding algorithms based on the data identified by the coal-rock identification sensor can the seed layer site be selected. After the seed layer site is selected, tracking can be carried out using the seed layer site.

[0052] To identify coal and rock layers, it is necessary to conduct in-depth research on single-channel waveforms and find out the laws of their changes. The forward simulation method can be used to first simulate the most ideal coal and rock structure model through GPRMAX, and then use amplitude and spectrum analysis to find out the waveform characteristics corresponding to the coal and rock layers, thereby completing the identification of the coal and rock layers.

[0053] The positioning of coal-rock layers is the premise of tracking and extracting coordinate information, including the positioning of direct waves and air interface layers, and the positioning of coal-rock layers. Through in-depth analysis of the quantitative relationship between the layers, the corresponding algorithms are used for positioning. The basic idea of ​​coal-rock layer positioning: select any data sequence in the preprocessed radar data, and determine the channel number of the selected data sequence: where the channel number of the selected data sequence is recorded as T0. Determine the position of the direct wave and the number of sampling points N0; determine the position of the air interface layer and its number of sampling points N1 through the number of direct wave sampling points N0; determine the position of the coal-rock layer and its number of sampling points N2 through the number of air interface layer sampling points N1.

[0054] The basic idea of ​​the coal-rock stratum adaptive tracking method is to first obtain the data collected by the coal-rock identification sensor and preprocess it, then select the seed point based on the preprocessed data, and then use the window operator to take the seed layer site as the starting reference center to track the stratum of the preprocessed data, confirm the stratum geographic coordinate information of the two parts of the data sequence of all tracked tracks and the starting reference track, and finally, based on the stratum geographic coordinate information of all track data sequences, make a coal-rock stratum occurrence curve diagram.

[0055] Step 4: Control the motion module 2 to perform jog movement to perform exploratory coal-rock structure identification; jog control the motion module 2, click the motion module once to drive the coal-rock identification sensor to move, and perform exploratory coal-rock structure identification according to actual needs.

[0056] In this embodiment, the performance analysis of the coal rock identification sensor is performed based on the coal rock structure identification results at a given position in step 2, the coal rock structure identification results at all positions in step 3, and the exploratory coal rock structure identification results in step 4.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope defined by the claims of the present invention.
