| 摘 要： | 针对矿井面临的测量误差大、测量难度大等问题，采用井巷测量控制点偏心改正技术，通过对测站点偏移及测站点归心改正分析，以新田煤矿1402回风巷一组控制点偏移为实例，然后把该技术应用工作面贯通测量，研究导线长度为2 862 m，测站为36站，偏移改正6测站，最终贯通精度，导线相对闭和差为1/10 023，坐标方位角闭和差为±27″5。实践表明，井巷测量控制点偏心改正技术能有效解决导线延伸过程中存在的难题，提高了测量效率，缩短了现场等待的时间，提高导线延伸的时效性，为开掘生产及时提供服务。

| Abstract: | In allusion to the mine measurement error，measurement difficulties and other issues，by using the technique of eccentric correction in the measurement of control points in the roadway and by analyzing the deviation of the measuring points and the centering of the measuring points，a set of control point offset in a coal mine was taken as an example.Then，for 2 862 m，the station was 36 stations，offset correction 6 stations，the final penetration accuracy，the relative closure and the difference between the wires was 1/10 023，the coordinate azimuth and the difference between the closure and ±27 ″5，the practice showed that the measurement control Lane.The technology of point eccentricity correction can effectively solve the problems existing in the extension of the wire，to improve the measurement efficiency，to shorten the time waiting in the field，to improve the timeliness of wire extension and provide timely service for digging production. |
