Project Features:
Design holes depth 900-1100 meters, ultra-deep holes construction, complicated strata
Project representative results:
It took 45 days to drill the final hole with 75mm diameter and 85° dip Angle to 1142.4 meters and successfully finished the hole, which set a record for the depth of 75mm diameter of the same type drill in China.
It took 30 days to drill the final hole with 75mm diameter and 82° dip Angle to 936.2 meters and successfully finished the hole.
