井间巷道贯通测量方案及精度控制研究

Research on Scheme and Precision Control of Roadway Holing-through Survey between Shafts

对井间巷道贯通测量中涉及的GPS测量、陀螺定向测量、联系测量以及全站仪测量等的误差进行了分析。采用先进的测量设备及合理的数据处理分析方法确保测量精度,根据测量结果及时修正巷道掘进方位。采取上述测量精度控制措施后,巷道贯通点K水平、高程误差分别为-182 mm、-126 mm,满足井间巷道贯通精度要求。

This paper analyzed the errors of GPS,gyro orientation,contact survey and total station survey in the holing-through survey of roadway between shafts.And it adopted advanced measuring equipment and reasonable data processing analysis method to ensure the measurement accuracy,and timely correct the heading direction according to the measurement results.After taking the above measurement accuracy control measures,the K level and elevation errors of the roadway holing-through point were-182 mm and-126 mm respectively,which met the requirements of roadway holing-through precision between shafts.
