掘进巷道导线测量方法优化应用

Optimization and Application of Traverse Survey Method in Heading Roadway

基于两渡煤矿集中运输巷二段掘进期间导线测量时传统全站仪导线测量方法效率低、劳动强度大且导线测量误差率高等技术难题,两渡煤矿通过技术研究,决定对原导线测量方法进行优化,提出了“全站仪三脚架法以及长角短边测量法”。导线测量方法优化后,测量作业人员由原来的5人减少为3人,测量精度提高至98%以上。

When conducting traverse survey in the second section of the centralized transportation roadway of Liangdu coal mine,there are technical problems such as low efficiency,high labor intensity and high traverse error rate of the traditional total station traverse survey method.Based on this,through technical research,it is decided to optimize the original traverse survey method and put forward"total station tripod method and long angle short side survey method".According to the actual application results,after the optimization of the traverse survey method,the number of operators in the survey is reduced from 5 to 3,and the measurement accuracy is increased to more than 98%.
