Maximal increase of exploration availability of the drill due to the newest engineering developments

The experts of Rudgormash engineering bureau are professionals in their field and operate the knowledge for optimization of the life cycle of the quick-wear spare parts. As a result, the following changes in the drill construction have been introduced:

  • An additional oil cooler in the hydraulic system of the drill has been installed for the stable operation of the hydraulic system due to lowering oil temperature in a hot environment.
  • The heat-insulated structure of the water tank provides permanent operation of the drill in the cold conditions of the North.
  • Construction of an operator’s chair with control panels on both sides of its armrests was successfully implemented and presently undergoes field tests.
  • A CAN-line has been applied to replace hundreds of cables used before.
  • The very recent models of our drilling rigs have a video control system that helps the operator control all major processes of the machine work like lifting and lowering of the drill tool head when screwing and unscrewing the rods, the hole condition, the rest device condition and the compressor unit operation data.
  • Wireless control of the drilling rig track assembly can be applied on the latest modifications. Remote travel control is used for this purpose.
  • Additional back gauges of the travel reduction unit are used to prolong the life cycle of the reducer and to prevent its early breakdown.
  • To improve operational characteristics we have designed and put under field tests the temperature control system of the supporting unit and the oil pumping station.


Drilling rigs


The rotary blasthole drilling rig SBSH-250D is specified for drilling blast holes with diameter 171-270 mm in hard highly abrasive rocks. The diesel drive provides autonomy which meaningfully decreases time and expenses for moving the drilling rig not depending on remounting the network of the quarry.

  • The installed diesel engine Cummings QSK19 with power 650 H.P. is notable for low fuel consumption and reliability. The serial location of the compressor, engine and pump unit makes easier their technical maintenance. The fuel tank with capacity 2,5 m3 provides day round work of the drilling rig.

The rate of penetration remains constant independent from the bit load at empty spaces and fissuring in the
    drilled rocks. The hydraulic drive has the idling mode that keeps the temperature conditions of the hydraulic system in the state of constant readiness which is very effective in wintertime.
  • The drilling rig is equipped with the compressor with productivity 28 m3/min or 40 m3/min which depends on the diameter of drilling. The rational assembling of the main units of the drilling rig provides stability while moving and drilling.
  • The mast frame of closed type provides firmness and reliability of the whole structure at the speed force of 35 tons and torque of 1300 kgf·m.
  • The rope and polyspast drive of feeding the drill tool from two hydraulic cylinders allows reducing stress and vibration while drilling rocks with cracks. The bearing unit and the rotor are executed separately which also prevents the rotor from stress and vibration.
  • Станок комплектуется компрессором производительностью 28 м3/мин или 40 м3/мин в зависимости от диаметра бурения.
  • The cabin of bigger size has heated windows and warmed walls, floor and ceiling. The heater and air conditioner are also provided. The anti-vibration chair, steering board and industrial computer with all the drilling parameters data on its screen with constant diagnostics of the drilling rig units are also located inside of the cabin.

Drilling rigs


The electric drill is designed for drilling blast holes in rocks with hardness of 6 – 20 units according to Prof. Protodyakonov scale at open-pit mines.
The drill consists of the crawler mounting, the engine room, the mast and the operator’s cabin.

The crawler mounting of the drilling rig consists of two independent trolleys, connected by axles, with the drive for each trolley. Links, wheels and rollers are made of heat-treated high-alloy steel.

The track tension is carried out by the double-sided hydraulic actuator. Chassis incline and mounting of the guide wheel at cantilever axle exclude
their sludging and pickup of soil in wet conditions. Closed bearings filled with lubrication for all life-time cycle are applied at bearing units of the crawler mounting.
The engine-room of the drill implated hard-welded construction. The engine-room has the following equipment inside:

  • the compressor unit
  • the oil-pumping station, including the following basic elements
  • the main pumps with the regulated pumping capacity that provides weight to drill tool head and other operations
  • an auxiliary pump provides prompt lowering and lifting of the drill tool during make-and-break operations
  • the rotation unit and the track drives
  • the electrical cabinets
  • two frequency converters to control asynchronous motors of the rotation unit and hydraulic pump when the rig is drilling.

The mast is a space frame attached to the engine-room with the help of friction bearings. Two hydraulic cylinders do the lowering and lifting of the mast. Two retaining devices (mechanic or hydraulic) keep the mast in its operating condition (up). The mast has all the necessary units for performing basic and auxiliary operations when drilling.

SBSH – 250MNA-32KP

The machine is applied for drilling blast holes of 250- 311mm in diameter in rock with hardness up to 20 units according to prof. Protodyakonov scale.

The frame-platform design of the drill provides reliability of the whole construction when the drill operates in a complex mining and geological environment.

The compressor unit of 50m3/min capacity enables the efficient operation of the drill tool and provides proper cleaning of the holes from the drill fines. Our drilling rigs of heavy type have successfully gone through operational testings at the iron ore quarries. The ore was drilled with rods of 290 mm in diameter, later the diameter was expanded to 311mm.

The results have shown high efficiency of the drill and advantages that a buyer can get as a result of the increased productivity like the reduced energy consumption during mining and reduction by 20% of the over-sized lumps if compared to the drilling rigs with rods of 250mm in diameter. All that will allow you to reduce expenses on crushing the over-sized rocks.

SBSH-250MNA-32KP for drilling holes of 311mm in diameter at iron ore mines can earn more for its owners and increase the mined material output from 1 long meter by 35-40% if compared to drills with rods of 250mm in diameter. The oversize yield is cut down by 20%, as the result, we have reduced expenses on crushing.
