高程导入方法在矿山测量中的研究

Method of Elevation Introduction in Mine Survey

传统地表形变监测技术存在工作强度大、覆盖面积小、工作效率低等问题,不能满足新阶段矿区地表沉降监测的需求。近年来,卫星遥感地面观测技术的进步,以及星载合成孔径雷达干涉测量技术(Interferometric Synthetic Aperture Radar, InSAR)的出现,提高了地表沉降监测的准确性,这2种技术能够拍摄出高清晰度的地表图片,具有持久的空间覆盖能力。分析了在煤炭开采过程中高程导入测量的意义与核心,同时也探索了一些经典的立井高程导入技术,针对大型深井立井高程导入这一挑战性问题,提出了解决策略。

The traditional surface deformation monitoring technology has the problems of high work intensity,small coverage area and low work efficiency,which can not meet the needs of surface subsidence monitoring in the new stage of mining area.In recent years,the progress of satellite remote sensing ground observation technology and the appearance of spaceborne interferometric synthetic aperture radar(InSAR)have improved the accuracy of surface subsidence monitoring.These two technologies are is capable of taking high definition pictures of the surface and has the capability of lasting space coverage.The significance and core of elevation introduction measurement in coal mining were analyzed,some classic shaft elevation introduction techniques were explored,and solutions to the challenging problem of large deep shaft elevation introduction were put forward.
