Drilling rigs of the DM series have been gaining great popularity in our region and in the world in recent years. They have proven their effectiveness and reliability in difficult operating conditions, and are also recognized as autonomous, maneuverable and safe. The Epiroc DM75 D drill is designed for rotary drilling of vertical and inclined wells. The maximum drilling depth is 51.2 m when using rods longer than 10 m.
Artem Kuznetsov, Head of the Mining Development Department, Mining Department, ArcelorMittal Kryvyi Rih:
- The company's management has decided to update the drilling equipment fleet, because drilling is the initial operation on which the entire subsequent production chain and the production process as a whole depend. The modern Epiroc DM75 D is equipped with an upgraded clutch, powerful low pressure compressor, 800 horsepower Caterpillar diesel engine. The machine is not tied to power grids, this gives it the ability to move quickly, maneuver and work in any weather. The productivity of the machine is up to 10 running meters per hour. It is important that the drilling process will become more environmentally friendly thanks to the installed wet dust control system.
The DM75 D has several features to provide the operator with a safe working environment. The unit is equipped with a feed holding valve, leveling jacks and load holding valves. The comfortable cab with improved visibility is FOPS (Falling Object Protective Structure) certified. The monitor in the driver's cab displays the parameters of the rig and drilling: the position of the rod, speed and depth. All the operating functions of the machine are controlled from a special panel, the ergonomic layout of which allows you to quickly switch from drilling mode to moving mode, which increases work productivity.
Altogether, at the moment, ArcelorMittal Kryvyi Rih uses four SBSh drilling rigs, five Pit Viper machines, an electric drill of the DM 75 E series and a Roc L8 rig for setting the edge positions of the pit sides. The new Epiroc DM75 D machine, after the registration of the necessary permits, will start working in the quarry No. 2-bis of the enterprise. The company's plans for 2021 include the purchase of another new contour drilling rig in quarries.
