The Present Status of the Geological Mineral Exploration Coring (Sampling) Drilling Equipment in China and Analysis-Research of Increasing the Drilling Efficiency

Abstract:

The present status and prospect of mineral exploration drilling market in China were summarized, and also the advantages and disadvantages and the comprehensive efficiencies of the conventional spindle drills and the fully-hydraulic top-drive head drills were discussed. Aiming to the actual situations and conditions of strengthening geological works brought forward by Chinese government, the author presented some viewpoints and proposals, which perfect and improve the present drilling equipment, increase the mineral exploration drilling efficiency, decrease the power consumption and the drilling cost.
