Abstract：By using UAV aerial survey technology,GNSS static measurement technology and real-time monitoring system technology,the monitoring data fusion research of multi-source data in the caving mining subsidence area of Jinchuan Copper-nickel Mine was carried out.By adopting the monitoring scheme of long period,short period and real-time monitoring interaction,GNSS technology success-fully makes up for the defects of UAV monitoring accuracy.The multi-source data monitoring carried out by the three methods at the same time can make up for the shortcomings of their respective moni-toring methods,and give full play to their respective monitoring advantages in data accuracy,monito-ring range and monitoring period,thus improving the timeliness and high precision of subsidence area monitoring.The results show that there are subsidence basins with monitoring points 5-9,6-4,7-10,8-6 and 7-14 in the caving mining subsidence area of Jinchuan Copper-nickel Mine.There are 15 sub-sidence pits,the deepest of which reaches 31 m,the cumulative maximum subsidence amount is-13.810 m,and the maximum subsidence rate of the monitoring point is-0.013 m/d.The research results can provide basic data needed for safety,science and reasonable production organization of caving mining in Jinchuan Copper-nickel Mine in later period.
