摘 要:为保证伯方煤矿羊圈港进风斜井与二水平西翼轨道大巷顺利贯通,对地面近井点联测、井下控制网联测、巷道导线联测方案进行阐述。分析计算伯方煤矿进风斜井贯通测量误差,经计算贯通测量高程误差闭合差fH为±139 mm,f_(h容)为±0.248 m,f_(H)<f_(h容),满足高程精度限差要求。经后期对贯通误差进行实测,贯通平面纵向误差为+0.063 m,横向误差为-0.14 m,贯通高程误差为+0.11 m,满足巷道使用条件。In order to ensure the smooth connection between Yangquangang air intake inclined shaft and the second level west wing track roadway in Bofang Coal Mine,the joint measurement schemes of ground near well point,underground control network and roadway traverse are described.Through the analysis and calculation of the through survey error of the air intake inclined shaft in Bofang Coal Mine,the closure error f_(H) of the through survey elevation error is±139 mm,f_(h允)is allowed to be±0.248 m,and f_(H)<f_(h允)is allowed to meet the requirements of the elevation accuracy tolerance.According to the actual measurement of the through error in the later stage,the longitudinal error of the through plane is+0.063 m,the transverse error is-0.14 m,and the through elevation error is+0.11 m,which meets the use conditions of the roadway.
