A Subsidence Numerical Model to Describing Iron Ore Mining Goaf and Its Related Countermeasures

摘要：

According to the specific geological conditions of Beiminghe iron mine and its mining methods,collapse height of the roof of mined out area is calculated with empirical formula firstly. Secondly,the numerical model is established based on the surrounding rock and the goaf replaced with collapse body,and FLAC3D software gob is used to simulate the final settlement value of iron mine. And based on the results,he subsidence control plan accordingly put forward. Results and treatment options has a certain reference value for predicting the depth and range of subsidence area formed and choosing the treatment program of caving mining.
