Application of On-line Monitoring System for High and Steep Slope in Nan-nihu Open-pit Molybdenum Mine
The high and steep slopes formed by open-pit mining have potential safety hazards due to landslides,posing a significant threat to the safety of downstream residents'lives and property.Using modern monitoring technology to monitor the stability of high and steep slopes is a necessary means to prevent disasters.The existing research theory basically relies on the corresponding monitoring technology to realize the slope monitoring and management,and lacks the system information integration platform,which is not conducive to the management of the mine in the overall safety production operation process.Therefore,a comprehensive framework for online monitoring data integration on the internet has been designed in this paper by using the principles of radar and GNSS monitoring technology.This framework allows for full time and comprehensive monitoring of displacement,blasting vibration,and other aspects of high and steep slopes in the Nannihu mining site and waste dump.Based on the data information obtained by the monitoring system,the landslide deformation characteristics and landslide inducing factors are analyzed.The appropriate monitoring indicators are selected to establish the threshold model,and the early warning threshold is calculated according to the model,which can divide the corresponding early warning level.The on-line monitoring system realizes the modern slope monitoring target of high precision,large area,non-contact,all-day,all-weather and early detection.The on-line monitoring system is safer,more efficient and more accurate than traditional manual monitoring,and plays a significant role in disaster warning.
