Abstract: Considered many factors of the open-pit geological safety and combined the need open-pit modernization construction, a comprehensive geological safety monitoring system for Haerwusu open-pit has been established for the geological safety issues of Haerwusu open-pit. The monitoring system establishes the database by automatically collecting and sending real-time monitoring data, then processes and analyzes the monitoring data. The monitoring system solves the difficulties of geological safety monitoring and prediction which reduces the human and material resources and also improves work efficiency.
