[0036] The present disclosure is further described below in conjunction with the accompanying drawings and specific embodiments.

[0037] In order to solve the technical problem in the prior art of lack of a unified arrangement of drilling end holes, which affects the efficiency and success rate of drilling design, the present invention provides a liquid injection drilling arrangement method and related devices based on a three-dimensional model of a coal seam.

[0038] Figure 1 The three-dimensional structure diagram of the coal seam and the tunnel is shown. Figure 1 As shown, during the coal mining process, it is necessary to drill a hole from the tunnel 1 into the coal seam 2, forming a drilling path 4 between the drilling start point and the drilling end point 3 in the tunnel, and forming a wetting range 5 around the drilling end point 3.

[0039] Figure 2 The flowchart of the steps of the method for arranging liquid injection drilling holes based on the three-dimensional model of the coal seam provided by the present invention is shown as follows: Figure 2 As shown, the method for arranging liquid injection drilling holes based on the three-dimensional model of the coal seam includes the following steps:

[0040] S101, obtaining basic information of the injection drilling hole, wherein the basic information includes coal seam information and tunnel information.

[0041] In this step, basic information of the injection borehole is obtained, wherein the basic information includes coal seam information and tunnel information.

[0042] Specifically, the coal seam information and tunnel information are determined based on the mine plan and geological profile, including the coordinates of the left and right sides of the tunnel, the elevation of the starting point, the coordinates of the slope change point and its elevation, the height of the side of the arched tunnel, the arch height, the inclination of the coal seam, the thickness, and the bottom plate elevation.

[0043] S102: construct a three-dimensional coordinate system based on the basic information.

[0044] After completing the above step S101, in this step, a three-dimensional coordinate system is constructed based on the basic information.

[0045] Specifically, after obtaining the above information, the C# programming language is used to perform secondary development on CAD, and a three-dimensional drilling design system is constructed. The parameters required for the above-mentioned three-dimensional automatic design of drilling holes are obtained through the tunnels, drilling sites, and coal seams on the plan and section drawings of the working face, and the drawings and the design parameters entered by the user are saved by building a database. This setting method is conducive to showing the stratigraphic relationship between the construction tunnel and the target coal seam by establishing a three-dimensional model, providing a model basis for the next step of drilling design, and making up for the defects of the traditional drilling design carried out in two-dimensional space that is inaccurate and non-intuitive.

[0046] Based on the data information of the mine plan drawings and their corresponding multiple geological profiles, the coordinates of the left and right sides of the tunnel, the elevation of the starting point, the coordinates of the slope change point and its elevation, the side height of the arched tunnel, the arch height, the coal seam inclination, thickness, the floor elevation and other parameters were preprocessed, and the coordinates of each characteristic point in the tunnel and coal seam model were calculated. The three-dimensional wireframe model was divided, and the Delaunay triangulation algorithm was used to construct the TIN triangulated mesh model of the upper and lower surfaces of the coal seam and the tunnel.

[0047] Furthermore, numerical simulation is used to analyze the influence of different injection parameters on the wetting-resistance range of the coal body under the conditions of real coal body structure, and the injection effects of coal seams with different hole layouts are compared. According to the actual occurrence of coal bodies in the mine, the wetting-resistance radius of coal seam injection is determined to provide a data basis for injection drilling design. Among them, the three-dimensional model of the coal seam and the borehole is imported into the numerical simulation software, and the injection parameters are adjusted to realize the visualization of the wetting process and wetting range of the inhibitory liquid under different injection pressures and injection times, so that the injection effect under different injection parameters can be evaluated through simulation results.

[0048] In order to accurately reflect the contours of the tunnel and coal seam, the elevations of the opening and ending holes are input into the 3D drilling design system, the characteristic point information such as the slope change point is entered according to the undulation of the tunnel, the top contour of the tunnel is selected and its related parameters are entered, so as to construct a 3D model of the tunnel where the drilling construction is located. This setting method is conducive to the rapid and accurate design of coal seam injection drilling holes; by collecting the contour points of the coal seam and the tunnel, not only the upper and lower surfaces of the coal seam can be efficiently constructed, but also the undulation and fault conditions of the coal seam can be more accurately presented.

[0049] S103: Determine a starting point and an end point based on the three-dimensional coordinate system.

[0050] After completing the above step S102, in this step, a starting point and an end point are determined based on the three-dimensional coordinate system.

[0051] Specifically, after the three-dimensional model is established, Figure 1 As shown, a point is selected in the tunnel as the drilling start point, and a point is selected in the coal seam as the drilling end point; liquid injection drilling is realized from the drilling start point to the drilling end point.

[0052] S104: Determine a drilling path based on the starting point and the end point.

[0053] After the drilling start point and the drilling end point are determined, in step 1, a drilling path is determined based on the start point and the end point.

[0054] Furthermore, if Figure 3 As shown, determining the drilling path based on the starting point and the end point includes the following steps:

[0055] S201, generating a drilling vector according to a drilling start point and a drilling end point.

[0056] In this step, a drilling vector is generated according to the drilling start point and the drilling end point.

[0057] Specifically, after determining the starting point and the end point of the drilling, a drilling vector is determined based on the starting point and the end point, wherein the drilling vector is determined in the following manner:

[0058]

[0059] Where M represents the drilling vector from the starting point A to the end point B, that is, A indicates the starting point of drilling; B indicates the end point of drilling; (X B ,Y B ,Z B ) represents the three-dimensional coordinate point of the drilling end point B; (X A ,Y A ,Z A ) represents the three-dimensional coordinate point of the drilling starting point A.

[0060] S202, determining a drilling angle and a length value of the drilling vector according to the drilling vector, wherein the drilling angle includes α, β and θ, and α, β and θ are angles between the drilling vector and the X, Y and Z axes, respectively.

[0061] After completing the above steps, in this step, the drilling angle and the length value of the drilling vector are determined according to the drilling vector, wherein the drilling angle includes α, β and θ, and α, β and θ are the angles between the drilling vector and the X, Y and Z axes respectively.

[0062] Specifically, the "regular hexagon inscribed in a circle" is used to step the drilling end point, and the position of the drilling end point is calculated.

[0063] First, after determining the drilling start point and the drilling end point, determine the length value of the drilling vector, which is obtained by the following method:

[0064]

[0065] Among them, L M Represents the length of the drilling vector, and || represents the modulo function.

[0066] After the length value of the drilling vector, determine the components of the drilling vector in the X, Y, and Z coordinate axes, where:

[0067]

[0068] Where P represents the component vector of the drilling vector M in the x direction, that is,

[0069]

[0070] Where Q represents the component vector of the drilling vector M in the y direction, that is,

[0071]

[0072] Where R represents the component vector of the drilling vector M in the z direction, that is,

[0073]

[0074] Among them, L P Indicates the length value of the component vector in the x direction;

[0075]

[0076] Among them, L Q Indicates the length value of the component vector in the y direction;

[0077]

[0078] Among them, L R Indicates the length of the component vector in the z direction.

[0079] After determining the length value of each component vector, the angles α, β and θ between the drilling vector and the X, Y and Z axes are determined based on the length value, where α, β and θ satisfy the following formula:

[0080]

[0081] S203: Determine a drilling path based on the starting point and the drilling angle.

[0082] After completing the above step S202, in this step, the drilling path is determined based on the drilling starting point and the drilling angle.

[0083] Specifically, the drilling starting point and the drilling angle are input into the three-dimensional model, so that numerical simulation of the drilling can be realized.

[0084] The method for arranging liquid injection drilling holes based on the three-dimensional model of the coal seam provided by the present invention is applied to obtain the basic information of the liquid injection drilling holes, wherein the basic information includes coal seam information and tunnel information; and construct a three-dimensional coordinate system based on the basic information, which is conducive to intuitively displaying the stratigraphic relationship between the construction tunnel and the target coal seam; and determine the starting point and the end point based on the three-dimensional coordinate system, and then determine the drilling path, so that the coal seam liquid injection drilling holes can be designed quickly and accurately, and the three-dimensional stereo images of the boreholes, tunnels, and coal seams can be automatically output, and the plane and cross-section diagrams can be automatically drawn, and the drilling construction parameters such as the opening coordinates, azimuth, and inclination angles can be automatically generated.
