Abstract: With the continuous mining of open-pit，slope stability becomes an important safety issue concerned in open-pit mining.However，for the traditional monitoring，there are many monitoring projects，large amounts of data and great difficulties in analysis.To deal with it，a monitoring system of slope displacement in open pit based on Beidou satellite system is designed and developed to achieve real-time and highly automated monitoring on slope displacement，and to scientifically and efficiently deal with the monitoring data.The general design and technical architecture of the system and the design and implementation of each subsystem′s functions are introduced in detail.The implementation of the system provide an effective technical means for slope monitoring，and also provide a basis for guiding the decision-making of managers.
