贯通测量误差预计是贯通工程中的一个重要环节。根据金翅岭矿区的实际情况,结合工程施工过程中的工作经验,选择适用于此次贯通工程的测量方案。应用误差理论,分析误差来源以及误差产生的影响因素,综合井上下的测角测边误差、水准测量误差以及联系测量时的投点误差、导入高程误差和陀螺仪定向误差,预计出水平方向与竖直方向的贯通偏差值可能出现的大小范围。此方案在保证贯通精度的前提下尽可能地降低施工成本,既为贯通施工提供正确、合理的设计指导,又为以后的井巷测量积累了资料与经验。
Through measurement error is expected to be an important part of the project. According to the actual situation of the Jin-Ridge mining area, combined with the work experience in the construction process, select the measurement scheme suitable for this through engineering. Based on the theory of error, the source of error and the influencing factors of error, this paper synthesizes the measuring error of the measuring angle, the leveling error and the throwing error in the contact measurement, introduces the elevation error and the gyroscope orientation error, Pitch through the vertical direction of the possible size range. This scheme can reduce the construction cost as much as possible under the precondition of ensuring perforation accuracy. It not only provides correct and reasonable design guidance for continuous construction, but also accumulates data and experience for the future measurement of shaft and lane.
