Abstract EN
Modeling plays an important role in engineering exploration.
However, the traditional rectangular mesh cannot meet the requirement because the actual shape of the model may be very complex.
Therefore, this paper chooses the Delaunay grid for modeling and applies this method to magnetic numerical simulation.
At the same time, we make use of the advantages of the Delaunay grid and choose to use grid encryption technology in the boundary and complex area of the model.
Then, the formula for calculating the magnetic anomaly of tetrahedron is deduced in detail, and the magnetic anomaly with surface fluctuation is calculated.
For a synthetic data model, Delaunay grids with different densities are used to model and calculate surface anomalies.
The two results are compared with the analytical solution of the model.
The results show that the method has high accuracy.
Then, the method is applied to the actual geological body modeling in the Jinchuan mining area.
According to local needs, a three-dimensional model with inhomogeneous grid density is established and the surface magnetic field of the model is calculated.
Finally, the simulation data are compared with the measured data.
The results show that the Delaunay grid modeling method has strong applicability.
