爆力运矿采矿法的扇形中深孔测量

Measurement of Fan-shaped Moderate Longholes in Explosive Ore-handling Mining

在应用爆力运矿采矿法时,扇形中深孔的测量对保证凿岩施工质量和爆力运矿效果起着十分重要的作用。作者结合金山金矿的实际情况,详细介绍了扇形中深孔测量工作的技术资料准备、现场施测和验收测量,及实测数据整理,可供类似矿山参考。

When the explosive orehandling mining is used, the measurement of fanshaped moderate longholes is of very importance to ensuring the quality of rock drilling and the effects of explosive ore-handling. Combined with the actual conditions of Jinshan gold mine, a detail introduction to the preparation for technical information, the site construction/acceptance measurement and the measured data processing in the measurement of fan-shaped moderate longholes is made, which can be used as a reference for the similar mines.
