Time: 2012
Site : Huo Qiu, An Hui Province
Project : General exploration for Iron Mine
Hole Depth: 1000m - 1500m
Thickness of Quaternary System : 400m, complex strata
Adopted 2 sets of drilling machines , XY-5 & XY-6 ,equipped with large diameter rod ,drilled step by step. Efficient chemical mud material used during complex strata construction. Finally ,we created the fastest record among the whole teams with average drilling depth of 700m monthly per unit . Shortened the construction period , and won the time for the PART A .
