矿山巷道贯通测量精度估算新方法初探

为了直观揭示矿山井下巷道贯通测量精度估算工程和规律,采用全站仪井下巷道贯通导线测量,结合南方CASS9.0绘图软件,摸索出一种全站仪结合CASS9.0绘图软件进行井下巷道贯通测量精度估算试验的方法。提出支导线的终点是支导线精度的最弱点,横向贯通中误差是由全站仪导线测角、测边误差所引起,巷道内高程的控制测量精度直接影响的是竖向贯通中误差;并且通过在某矿山井下贯通测量精度估算工程的试验应用,研究结果表明:该方法达到了预期精度效果,解决了全站仪结合CASS9.0绘图软件进行井下贯通测量精度估算的方法问题。

Mine Roadway Expedite New Method Estimating Accuracy

To intuitively reveal mine roadway expedite precision estimation of engineering and rule, using total station un derground roadway expedite traverse survey, combined with the south CASS9. 0 drawing software, for a total station combined with CASS9. 0 drawing software for underground roadway expedite estimation accuracy test method. Put for ward for the end of the conductor is the lead accuracy of the weaknesses, the horizontal runthrough error is made up by total station traverse measuring Angle, measuring error caused by, the roadway to the control of elevation measurement precision directly affects the vertical penetration in error; And through the test of a mine through measuring accuracy esti mation of engineering application, the results show that this method has achieved expected effect of precision, to solve the total station combined with CASS9. 0 drawing software for downhole through measuring accuracy estimate method.
