In this study, the physical similitude modeling method and field observations were used to study the breakage and migration law of overlying strata in the downward mining of extremely close coal seams. Results show that in the process of mining upper coal seam, the first weighting step of the main roof is 37.5 m and the periodic weighting step ...

The actual caving is simulated implicitly in these continuum models. Observational data on cave development and surface cratering, as well as measured ground surface deformations, were used to calibrate the numerical models. For both approaches, deeper mining was shown to significantly affect the ground surface.

In geology, numerical modeling is a widely applied technique to tackle complex geological problems by computational simulation of geological scenarios.. Numerical modeling uses mathematical models to describe the physical conditions of geological scenarios using numbers and equations. Nevertheless, some of their equations are difficult to solve directly, such as partial differential equations.

• Numerical Modeling Methods • Empirical Methods . The models based on theoretical and numerical methods usually require extensive information about the properties of the overburden to be properly calibrated for a particular field site. The models based on the empirical met hods require an extensive set of field data. 8.2 GRAPHICAL METHODS

A numerical three-dimensional model was developed using FLAC3D to achieve surface subsidence and slope stability. The results show that the slope remains fundamentally stable during the two-stage recovery. For safety mining design is not feasible during disasters.

Geologic modelling, geological modelling or geomodelling is the applied science of creating computerized representations of portions of the Earth's crust based on geophysical and geological observations made on and below the Earth surface. A geomodel is the numerical equivalent of a three-dimensional geological map complemented by a description of physical quantities in the domain of .

These problems indicate that the whole issue of rock characterization should be realized and adjusted for using different methods of numerical modelling. The use of different numerical models requires different types of rock mass characterization. Therefore the success of a numerical model is in capturing the rock reality characterization ...
