摘要
贯通测量在矿山测绘中的应用,能够在一定程度上保证巷道掘进的精度与安全。本文以西南某金属矿山的实际测绘项目为例,探讨贯通测量技术的整个应用过程。研究采用全站仪测量与激光扫描技术相结合的方案,解决矿山复杂地质条件下的测量挑战。并以最小二乘法进行误差平差,构建出高精度的三维巷道模型。结果显示,其测量结果水平误差在±2mm以内,高程误差在±3mm以内,符合矿山掘进的精度要求。结果表明,贯通测量技术在矿山测绘中的应用能够极大的提升其测量精度与效率,具有着重要的工程应用价值。
The application of through measurement in mining surveying can ensure the accuracy and safety of tunnel excavation to a certain extent.This article takes the actual surveying project of a metal mine in Southwest China as an example to explore the entire application process of through measurement technology.The research adopts a combination of total station measurement and laser scanning technology to solve the measurement challenges under complex geological conditions in mines.And use the least squares method for error adjustment to construct a high-precision 3D tunnel model.The results show that the horizontal error of the measurement results is within±2mm,and the elevation error is within±3mm,which meets the accuracy requirements of mining excavation.This result indicates that the application of through measurement technology in mining surveying can greatly improve its measurement accuracy and efficiency,and has important engineering application value.
