摘要：The research on the three-dimensional simulation of caving zone in goaf is relatively few, so a three-dimensional modeling algorithm for the caving zone in goaf is proposed in this paper. The method firstly estimates the height of the caving zone based on empirical formulas and forms the filling zone; secondly generates original spherical fall-off blocks of different particle sizes; then uses the principle of spherical tangent to fill the caving zone randomly. This method avoids the impractical drawbacks of the filling problem and makes the three-dimensional simulation of the caving zone faster.
