摘要
利用无人机航测技术、全球导航卫星定位系统(GNSS)静态测量技术以及实时监测系统技术3种技术手段,进行了金川铜镍矿崩落法采矿塌陷区多源数据的监测数据融合研究.通过采用长、短周期和实时监测交互的监测方案,实现了 GNSS技术成功弥补了无人机监测精度的缺陷.3种方法同时进行的多源数据监测能够很好地弥补各自监测方式的短板,在数据精度、监测范围和监测周期等方面充分发挥各自监测优势,从而提高了塌陷区监测的时效性与高精度化.研究结果表明:金川铜镍矿崩落法采矿地表塌陷区出现监测点5-9、6-4、7-10、8-6、7-14为范围的沉降盆地,出现15个塌陷坑,其中最深的达到31 m,累计最大沉降量为-13.810 m,监测点最大沉降速率为-0.013 m/d.研究结果可为后期金川铜镍矿崩落法采矿提供安全、科学和合理组织生产所需的基础数据.
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.
