Kuzbassrazrezugol Coal Company Tested a New Generation Domestic Drill Rig

Kuzbassrazrezugol Coal Company (an enterprise of the UMMC raw materials complex) put an MR-200 diesel-hydraulic drill rig manufactured by IZ-KARTEX (a member of of the UZTM-KARTEX Group) into pilot operation.

The machine is designed for drilling vertical and inclined boreholes in surface mining of coal deposits. This is the first domestic medium-class diesel-hydraulic rotary drill rig.

“Testing will last three months, the designer of the machine will be here during this time,” says Evgeny Borisenko, CEO at Kuzbassrazrezugol-Vzryvprom.

“Technical support for the tests will be provided by New Technologies of Western Siberia LLC. We hope for positive results and performance not lower than that of similar machines in this class.”

The drill rig was designed by IZ-KARTEX in partnership with New Technologies of Western Siberia LLC and it took a few years to build. The planned output of the machine is 25 kilometers of drilled boreholes per month.

“The site for testing was not chosen randomly: the coal company has been cooperating with domestic manufacturers of open-pit mining equipment for many years,” says Roman Smirnov, Deputy Director for Production at Kuzbassrazrezugol Coal Company. “For example, all new generation UZTM-IZ KARTEX shovels were tested at Kuzbassrazrezugol enterprises. Working in tandem, from receiving specification requirements to launching into commercial operation, allows the manufacturer to promptly eliminate defects of new models, while we get high-performance equipment that fully meets our needs.”

The MR-200 drill rig incorporates modern design and technology solutions. The main and auxiliary mechanisms of the machine are fully hydraulically driven, which allows to significantly reduce their weight compared to similar electrically driven components.

“The drilling depth of the MR-200 can be 56 meters,” says Stanislav Tikhomirov, Chief Project Designer at IZ-KARTEX Design Directorate. “Drilling can be vertical and inclined, of up to 30 degrees. Particular attention has been given to the design of the operator’s workplace.”

The machine is equipped with an ergonomic cab with ventilation, heating (including autonomous heating) and incoming air filtration systems. There is vibration protection for the operator. Accurately calculated location of control elements allows the operator to adapt quickly to the workplace. In the future, the machine’s control system will enable monitoring of the drilling process and remote feedback control.
