Description

Technical Field

[0001] The invention relates to the technical field of mine hydrogeology, and in particular to a method for obtaining hydrogeological parameters of a ore deposit by visual programming. Background Art

[0002] Acquiring aquifer parameters is an important part of hydrogeological work. In the process of mining, water discharge test is often used to obtain aquifer parameter values, and then evaluate the hydrogeological conditions of the aquifer. Usually, the majority of engineering and technical personnel or researchers use conventional theories and methods to calculate hydrogeological parameters. Some scholars have also optimized the calculation methods of aquifer conditions and influence radius, but there are a large number of water discharge holes on the coal mining face and the water volume varies greatly. Manual calculation not only increases the amount of calculation and leads to a waste of human resources, but also easily causes loopholes that are prone to human errors in calculation and curve drawing.

[0003] Therefore, it is an urgent problem for those skilled in the art to propose a method for obtaining hydrogeological parameters of mineral deposits through visual programming to solve the problems existing in the prior art. Summary of the invention

[0004] In view of this, the present invention provides a method for obtaining hydrogeological parameters of a mineral deposit by visual programming, which helps to improve data processing efficiency and parameter accuracy.

[0005] In order to achieve the above object, the present invention adopts the following technical solution:

[0006] A method for obtaining hydrogeological parameters of a mineral deposit by visual programming, comprising the following steps:

[0007] S1. Use modeling software to standardize the ore deposit and generate a single-hole stable flow model and a multi-hole unstable flow model;

[0008] S2. Select a suitable model according to the construction hydrogeological holes and use VB program for interface design;

[0009] S3. When the model is a single-hole steady flow model, define variables and assign values, and iteratively calculate hydrogeological parameters;

[0010] S4. When the model is a porous unsteady flow model, the corresponding test curve is drawn using the semi-logarithmic graphical method or the line matching method;

[0011] S5. When the number of iterations is met or the standard curve is determined, the hydrogeological parameters of the ore deposit are obtained through conversion.

[0012] In the above method, optionally, S3 calculating the hydrogeological parameters includes using an iterative method to calculate the hydrogeological parameters based on the Joubert formula for single-hole stable flow in a confined aquifer and an empirical formula for influence radius.

[0013] In the above method, optionally, S3 specifically includes:

[0014] S301, determining hydrological parameters of the hydrogeological pores, and calculating the actual aquifer permeability coefficient and the actual influence radius based on the hydrological parameters;

[0015] S302, defining and assigning a virtual aquifer permeability coefficient and a virtual influence radius based on a single-hole steady flow model;

[0016] S303, judging whether the difference between the actual aquifer permeability coefficient and the virtual aquifer permeability coefficient, the actual influence radius and the virtual influence radius is zero, if not, repeating S301-S302, if yes, outputting the virtual aquifer permeability coefficient value.

[0017] The above method is optional. The semi-logarithmic graphical method in S4 is specifically as follows: when u≤0.01, the hydrogeological parameters are calculated by converting the Jacob formula for porous unsteady flow in confined aquifers;

[0018] in, r is the distance to the pumping well, a is the pressure conductivity of the aquifer, and t is the time from the start of pumping.

[0019] The above method, optionally, the semi-logarithmic graphical method is specifically:

[0020] S411, determine the VB design program interface, assign parameters and design semi-logarithmic coordinates;

[0021] S412, obtaining parameter data and assigning it to a dynamic array, and using a function to draw a test curve;

[0022] S413, calculate parameters and read values, and correct the test curve;

[0023] S414. Calculate and obtain hydrogeological parameters based on the modified test curve.

[0024] The above method is optional. The wiring method in S4 is specifically as follows: based on the Theis formula and standard curve of porous unsteady flow in confined aquifers, a test curve is drawn, matching points are selected through wiring to read corresponding values, and the converted values ​​are substituted into the converted formula to calculate the hydrogeological parameters.

[0025] The above method is optional, and the wiring method is specifically as follows:

[0026] S421, determine the VB design program interface, assign parameters, design double logarithmic coordinates and draw a standard curve;

[0027] S422, obtaining parameter data and assigning it to a dynamic array, and using a function to draw two test curves;

[0028] S423, making the two test curves overlap to generate an overlap curve;

[0029] S424. Read the matching points based on the coincidence curves and calculate and generate hydrogeological parameters.

[0030] It can be seen from the above technical solution that, compared with the prior art, the present invention provides a method for obtaining the hydrogeological parameters of a mineral deposit by visual programming, which has the following beneficial effects: the present invention adopts VB visual programming software to calculate the hydrogeological parameters, and uses language programs to make up for the loopholes that are prone to human errors during calculation and curve drawing, effectively improving the data processing efficiency and the accuracy of the parameters, making the calculation of the hydrogeological parameters of the mineral deposit more concise, efficient and accurate.
