河台金矿高村矿区盲竖井测量精度提高的方法

经误差估算,指出河台金矿原有的井下支导线精度不能满足拟掘盲竖井工程测量的需要;采用2井定向和提高测角精度的方法,并通过相关精度计算,可以提高局部导线的相对精度,解决该盲竖井的测量问题。

Proposal Improving Measurement Accuracy Method for Blind Shafts in Hetai Gaocun Gold Mine Area

After the error estimation,it is pointed out that the precision of the original underground wire branch in Hetai Gold Mine can not meet the requirement of the proposed blind shaft excavation engineering survey.Improving the relative precision of local wire branches can resolve the survey issue of this blind shaft through the precision calculation by adopting two directional wells and improving the accuracy of angle measurement.
