矿山井下惯性测量系统的仿真研究

Study of the Emulation of Inertial Survey System in Mining Surveying

──本文从矿山测量角度分析了用于矿山井下测量的惯性测量系统的实现要求，其中，定位精度要求在１０公里范围内惯性测量系统的相对定位误差（均方根）应达到０．４ｍ～０．８ｍ；对捷联式惯性测量系统的仿真结果表明，陀螺仪常值和随机漂移率为０．０１°／ｈ时，选择合适的ＺＵＰＴ时间，目前的惯性测量系统能够满足井下测量精度要求。

Th is paper analyses the requirement of realizing an Inertial Survey System(ISS)used in mine,which relative position accuracy(1σ)must be less than 0.4～0. 8m in the trajectory of 10km. The results of emulation of ISS indicate that ex-isting ISS could meet the mining surveying when the gyro-drift rate is 0. 01°/h and the appropriate ZUPT is selected.
