In January of this year, Altayvzryvservice's team drilled 31,100 running meters on a Sandvik D50KS rotary rig, which is a record in blast hole drilling using this type of equipment.
The record was set at the Kyrgayskiy Sredny open-pit mine, located in the Kemerovo Region, in extremely difficult geological and climatic conditions. The team encountered a sufficiently strong rock and a high water cut of the massif (82%). The average well depth was 10 m with a standard single-pass drilling depth of 8.7 m for this rig model, which required additional operations to build up the drill string. During the month, 13 blocks were prepared for the production of massive explosions. The monthly result of drilling operations, equal to 31,100 running meters, was confirmed by instrumental surveying measurements.
Sandvik D50KS is a rotary drill rig with a 522 kW motor and is capable of drilling 152-229 mm wells to a depth of 45 meters. The high result was achieved due not only to the outstanding characteristics of the equipment, but also to the well-coordinated and professional work of specialists. Throughout its lifetime, Sandvik service engineers, together with Altayvzryvservice's mechanical service, regularly maintained the machine to ensure uninterrupted trouble-free operation.
“This record is highly predictable, since the D50KS is equipped with advanced technologies and was designed based on the many years of experience of our engineers in the field of creating blasthole drilling machines. We do not limit ourselves only to the sale of equipment and do our best to maintain its proper technical condition, "commented Pavel Golovichev, Director of the Western Siberia Region, Sandvik Mining and Rock Technology.
In turn, Sergey Grigorievich Lyushakov, General Director of Altayvzryvservis LLC, noted: “Such a high indicator is an example of stable, organized and professional work of miners. I am glad that this result was achieved without any preliminary preparation and became a natural outcome of clearly set tasks, which allows us to count on new industry records. ”
