坚硬岩层钻进工艺在兖州矿区施工中的应用

Application of hard rock drilling process at construction of Yanzhou Coal Field

本文介绍了在兖州矿区坚硬岩层中的钻探施工技术,简要总结了针对兖州矿区坚硬岩层中的钻探施工方法,从而给出了相对最优的在矿区坚硬岩层中的钻头选择、钻进压力、钻具组合等参数以及针对硬岩层进行不同的金刚石钻头选择,取得了较好的效果。

After introduction of the hard rock drilling technology at Yanzhou Coal Field, the hard rock drilling technique specific for the Yanzhou Coal Field is summarized, so as to bring about a better effect in making a comparatively excellent selection of drilling bits, drilling pressure, drilling tools combination and in deciding different diamond drilling bits aimed at different hard rock layer.
