工作面贯通测量技术实践与分析

Practice and Analysis on the Transfixion Measurement of Coal Face

本文根据某矿地质条件复杂,为保证首采工作面顺利贯通,通过对测量放线中导线的敷设、数据处理及其误差对贯通的影响与导线复测、平差和检核方法等问题进行分析研究,并成功应用于生产实践,确保了高精度安全贯通,为矿井按期投产奠定了基础。

The productive geological condition is complex in a Certain Coal Mine, to ensure the smooth transfixion of the first coal face, analysis and study on the conductor laying during the surveying setting out, date processing, its error effect on the transfixion, conductor repetition , adjustment, methods of calibration and so on, then applied to production practice successfully, and has realized the high precision and safety transfixion, which has laid a foundation for the mining commissioning on schedule.
