Abstract:At present, geological disasters in mines are mainly collapse, landslide, karst ground subsidence and debris flow. Geological disasters forecasting and relative countermeasures which are put forward according to specific situation in mines can not only effectively avoid and reduce the loss caused by geological disasters, but also maintain the normal operation of the mine and people's life and property safety. According to geological environment conditions of a certain limestone mine in Guangxi province, combining with the field investigation of geological environment problems, an impact assessment has been carried out, and specific treatment countermeasures are put forward as well.
