矿山救生孔的贯通测量误差预计理论分析

Analysis on Through Survey Error Estimation Theoretical of Mine Rescue Hole

矿山救生孔在煤矿应急救援中发挥着极其重要的作用。针对矿山救生孔施工中缺乏对测绘关键技术的深入思考,文中以某井工矿为例,对救生孔的贯通方案进行分析。重点讲述了误差预计理论,分析了地面、井下导线和井下定向误差对贯通相遇点的精度影响,并讨论了井下加测陀螺边时的误差预计理论。

Mine rescue hole played an extremely important role in the coal mine emergency rescue.In the paper,the through schemes of the rescue hole were analyzed taking a mine for example in allusion to the lack of deep consideration in key technology of surveying and mapping in mine rescue hole construction.Error estimation theory was narrated emphatically,the accuracy impact of the surface and underground wires and downhole directional error on the through meeting point were analyzed,and the error expected theoretical was discussed when the under-ground traverse in gyroscopic orientation.
