摘要
为掌握煤炭开采引发的地表与岩层变形规律,在固隆煤业XV4301工作面布设监测站,综合传统岩移监测法与全球导航卫星系统(global navigation satellite system, GNSS)、干涉合成孔径雷达(interferometric synthetic aperture radar, InSAR)、机载激光雷达(light detection and ranging, LiDAR)技术开展监测。监测站共有147个监测点,采用预制混凝土标桩,通过GNSS-实时动态载波相位差分(real-time kinematic,RTK)技术多期测量、哨兵1号A卫星数据InSAR监测及无人机LiDAR进行数据采集,并融合多源数据处理。结果显示,终采6个月后地表基本稳定,计算出工作面关键岩移参数,走向、倾向方向平均移动角分别为62°、66°,充分采动时的下沉系数为0.84,水平移动系数为0.36,为煤矿安全开采提供了参考。
In order to master the deformation law of surface and rock strata caused by coal mining,a monitoring station is set up at XV4301 working face in Gulong Coal Industry,and monitoring is conducted by integrating traditional rock displacement monitoring methods with global navigation satellite system(GNSS),interferometric synthetic aperture radar(InSAR)and airborne light detection and ranging(LiDAR)technology.The monitoring station comprises 147 monitoring points equipped with precast concrete stakes,and data acquisition is conducted through multi-phase GNSS-real-time kinematic(RTK)measurement,Sentinel-1 A satellite data InSAR monitoring and UAV LiDAR,with integrated processing of multi-source data.The results show that the surface is basically stable 6 months after final mining,and the key rock displacement parameters of the working face are calculated,the average displacement angles in the strike and dip directions are 62°and 66°respectively,the subsidence factor is 0.84 and the horizontal displacement factor is 0.36 under full subsidence,providing reference for coal mine safety mining.
