摘要
为了保证黄玉川煤矿主副两井之间运输大巷井上、下长距离高精度贯通,贯通前需进行测量作业优化设计。分析了工程中的GPS控制测量、联系测量、陀螺定向测量及全站仪导线测量等各个参数的实测精度影响因素,以确定观测方案和数据处理方法。在巷道掘进过程中,根据导线测量和陀螺定向结果及时调整掘进方向,并按带有误差的附和导线合理确定各种测量结果的权重,进行严密平差和数据处理,及时对贯通导线进行修正。结果表明:通过选用先进的测量技术和合理的数据处理方法,可以确保两井之间长距离精准贯通,此次20 km贯通工程精度达到水平方重要向误差-0.182 m,高程方向误差-0.128 m。
In order to ensure an accurate holing-through of the mine transportation roadway with a long distance at the surface and under- ground of mine between the main shaft and auxiliary shaft in Huangyuchuan Mine, an optimized design of the survey operation was conduc- ted before the holing-through.The paper analyzed the influence factors of each parameter site measured accuracy for the GPS controlled survey, connection survey, gyroscopic orientation survey, total station traverse measurement and others to determine the survey plan and the data processing method.In the beading process of the mine roadway,according to the traverse measurement and gyroscopic orientation re- sults as well as the timely adjusted heading direction and to the connecting traverse with the error, the weighting of different survey results was rationally determined ,rigorous adjustment and data processing were conducted and the corrections were made on the holing-through traverse timely.The results showed that the advanced survey technology and rational data processing method applied could ensure the long distance accurate holing-through between the two mine shafts.The accuracy of the 20 km holing-through project reached an error of -0. 182 m in the horizontal direction and an error of-0.128 m in an elevation direction.
