摘要
东曲煤矿+860水平西翼轨道巷与羊圈港进风斜井在进行贯通测量时,采用了高质量测量仪器,制定了合理的测量方案,并进行了施工测量,使此次贯通顺利接合。导线连测后,在水平重要方向上的闭合差为±406 mm,在高程上的闭合差为±104 mm,贯通测量精度可满足巷道掘进及安全使用需求。
High quality measuring instruments were used,a reasonable survey scheme was made,and construction survey was carried out in break through survey to make a smooth connection between Dongqu Coal Mine+860 horizontal west wing track roadway and Yangjuangang inlet inclined shaft.After the conductor was connected,the closure difference in the horizontal important direction was±406 mm,and the closure difference in the elevation was±104 mm.The through survey accuracy can meet the needs of roadway excavation and safe use.
