| Abstract: | During exploration in the Jingjiawa mine of the Yuzhou coalfield in Henan,a layer of approximately 90m feldspar quartz sandstone(so called the Pingdingshan sandstone) encountered severely reduced the drilling efficiency and over-consumed materials.Jump bit rotary drilling was applied to hole ZK-09 and achieved good result.This paper introduced diversified drilling applications in hard rock beds. |
