煤矿井下曲线巷道测量技术研究

Study on measurement technology of curved roadway in coal mine

针对煤矿井下曲线巷道的测量和施工问题,在分析了曲线巷道测量对施工质量和生产安全的重要作用的基础上,重点对弦线法、切线法、弦切法和任意弦长法等4种曲线巷道测量方法的测量原理、标定参数计算、现场标定方法及施工大样图绘制方法进行了研究,分析了不同方法的适用范围和优缺点,对煤矿井下曲线巷道的测量具有重要参考意义。

Based on measurement and construction of curved roadway in coal mine, as well as analysis of the important role of curve roadway measurement on construction quality and production safety, measuring principles, calibration parameter calculation, field calibration method and large sample drawing method of the four measuring kinds of curve roadway which were chord method, tangent method, string tangent method and arbitrary chord length method were researched. At the same time, application scope, advantages and disadvantages of different methods were analyzed, which have important reference significance to the coal mine roadway curve measurement.
