陀螺全站仪在长距离工作面贯通中的应用

Application of gyro total station in holing through survey of long distance working face

大采高长工作面对贯通测量精度要求较高,传统测量方法在井下特殊的作业环境中很难满足矿井的生产需求。通过在工作面两顺槽分别布设一条陀螺边的方法来提高测量导线精度。对此,以寺河煤矿3303大采高工作面贯通测量为例,分别从误差预计、现场操作方法、内业数据的处理等方面进行了论述。

The high mining height and long working face requires high accuracy in holing through survey, so it is difficult for the traditional measurement method to meet the mine production demand in the special underground working environment. By laying a gy-ro edge along two sides＇ roadway of the working face, the accuracy of measuring traverse can be improved. Taking No. 3303 working face with high mining height in Sihe coal mine as an example, the error prediction, field operation method and data processing in holing through survey were discussed.
