摘 要:针对白洞矿井下回采巷道贯通测量误差较大的问题,基于贯通误差估算法设计了贯通测量方案,分析了影响贯通测量误差的因素,进一步提出误差控制策略,并加以验证。结果表明:贯通测量水平方向的闭合差值减小到0.163 m,垂直方向的闭合差值为-0.114 m,设计的误差方案合理高效。Aiming at the problem of large hole-through survey error in underground mining roadway in Baidong Mine,a hole-through survey scheme was designed based on the estimation method of hole-through survey,and the factors affecting the hole-through survey error were analyzed.The error control strategy was further proposed and verified.The results show that the horizontal closure difference of the through-through measurement is reduced to 0.163m,and the vertical closure difference is-0.114m.The designed error scheme is reasonable and efficient.
