Problems solved by technology

Since there are many factors affecting the water inflow in underground mines, a simple mathematical model cannot accurately predict the water inflow, and the selection of empirical parameters is also greatly restricted, which greatly hinders the prediction of mine water inflow
There are many kinds of existing mine water inflow prediction models, mainly including linear regression model, multiple regression model, time series analysis, etc. linear factors, so it is difficult to establish a suitable model using traditional mechanical methods to predict water inrush in underground mines

Embodiment Construction

[0056] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0057] Such as figure 1 As shown, a mine water inflow prediction method based on the NGBM-PSO model includes the following steps:

[0058] Step 1: Through actual measurement, record the water inflow of an underground mine, and establish time series data X (0) ,

[0059] x (0) ={x (0) (t i )} (1)

[0060] where, i=1, 2, 3...n, x (0) (t i ) corresponds to the water inflow of a certain mine on the i-th day, and n represents the number of days recorded;

Abstract

The invention discloses a prediction method of mine water inflow based on an NGBM-PSO model. By constructing time series data of actual measured value of mine water inflow, the time series data is converted into monotonically increasing series, then the discrete sequence data are continually transformed by nonlinear differential equation, parameters a, b, r are introduced, based on Particle SwarmOptimization (POS) to optimize the parameters, establish the prediction model, solve the prediction formula: (shown in the description) used for mine water inflow prediction calculation. The inventionhas the advantages of definite prediction result, strong applicability and high accuracy.

Description

technical field [0001] The invention belongs to the technical field of mining engineering, in particular to a method for predicting mine water inflow based on an NGBM-PSO model. Background technique [0002] As an important technical means to predict mine water inrush, building a mathematical model has been widely used in the prevention and control of mine water inrush disasters. Since there are many factors affecting the water inflow in underground mines, a simple mathematical model cannot accurately predict the water inflow, and the selection of empirical parameters is also greatly restricted, which greatly hinders the prediction of mine water inflow. There are many kinds of existing mine water inflow prediction models, mainly including linear regression model, multiple regression model, time series analysis, etc. Therefore, it is difficult to use traditional mechanical methods to establish a suitable model to predict water inrush in underground mines.
