Abstract: Slope stability of B area reinforcement section in East Mine of Baiyunobo play an important role in the safety production.In order to ensure the security of mine personnel and property,the area constructed a comprehensive monitoring and management platform including dynamometers and sliding remote instruments.According to the actual situation of engineering,the comprehensive monitoring and management platform installed 35 sets of dynamometer,6 sets of sliding power remote monitor to monitor timely reinforcement state of the B area slope.Monitoring data adopted the technology of wireless transmission and the signals realize the unified collection and receiving,and are real-time transmitted to the monitoring and management platform.The platform set up respectively monitoring early warning value and informed mine technical personnel with messages and email.Over the past half year,the data of rebar stress meter and sliding remote monitoring instruments trend relatively stable and have large space to the safety warning value.The slope is in steady state.

Key words: Anchorage stress, Slope monitoring, Early warning value, Wireless data transmission
