Drilling Technology Used in Weathering Residual Bauxite Mine of Guinea

Publish Date: 10 June 2014

Abstract

Abstract

No circulation media core drilling and auger drilling were used for the bauxite prospecting in Bokai of Guinea. The engineering practice and the comparison test show that no circulation media core drilling has disadvantages of low effi-ciency, high cost, unstable core quality and high labor intensity in weathering residual formations;but with auger drilling technology, the drilling quality of design requirement by specification can be satisfied with lower cost and higher drilling ef-ficiency, the drilling efficiency is 6.77 times that of core drilling and the comprehensive construction efficiency is 3.5 times that of the core drilling.
