Key Technology and Equipment of 2000m Core Drilling
Abstract:This paper introduced the main achievements of “key technology and equipment of 2000m core drilling” in the “863” project: integration of drilling equipment and core drilling apparatus has been completed to form the ability of deep core drilling construction and demonstration; the specific project of crisis mine ZK43-1 construction in Jinqingding mine was finished with good borehole quality of termination depth 2212.80m, average drilling efficiency 1.65m/h and core recovery 98.6%; in this borehole construction, 3 pieces of record of depth in drilling and casing in China were created; and some experiences were accumulated in large project operating mechanism, industry-university-research cooperation mode and drilling technology demonstration mode.
