In just one month, drillers drilled 3,217 holes with sandvik D50KS roller drill, with the depth ranging from 3 to 27 meters, which greatly exceeded the original plan of 207%, and also set an industry record of 43,430 meters.

The maintenance of this drilling rig is jointly done by sandvik and Kedrovsky Open-pit Mine. The perfect cooperation between the two parties ensures the best dispatching rate and superior performance of the equipment, which is also the guarantee for D50KS to break the record.
In addition, there are many factors that contribute to this achievement: the enthusiasm of the team, the management of the mine, and the professional industry knowledge of the staff. It is worth mentioning that the rock hardness in the drilling area is very high, reaching 80-100 MPa, and the moving time of equipment between holes is minimized, which is extremely efficient and saves a lot of time.
