Drolshagen / Ulan Bator — Hausherr, in close cooperation with BTFE and the local joint dealer "Euro Khan LLC", has delivered the first blast hole drilling rig in Mongolia to a customer there. Following a roughly 7,500 km long journey on a freight train of the Trans-Siberian Railway, the ceremonial handover ceremony took place at the end of August 2018 at the works yard of the drilling company "Elgen Drilling LLC" in Ulan Bator. Immediately thereafter, the unit was transported to the Bayangol iron ore mine, 350 km to the north, where commissioning took place over the next 10 days. The customer's operating personnel as well as the employees of a Mongolian service company were all given extensive training. The workers were familiarized with the hydraulic and electrical system, both theoretically and practically, and thoroughly instructed in the rig's operation and maintenance. In addition, troubleshooting was also covered. At Bayangol Mine, about 6 million tons of iron ore are extracted each year by means of drilling and blasting. Elgen Drilling is entrusted here with boring tasks as a subcontractor, as are other companies, as well. The HSB 3000 is a state-of-the-art, robustly constructed, latest generation down-the-hole hammer drilling rig equipped with a two-stage high pressure compressor that delivers 25 m3/min of air at a pressure of 25 bar.
Here, it drills holes with a diameter of 165 mm at a depth of 20 m. In just two and a half months to date, the HSB 3000 has been operating for 1,000 hours and has achieved an average drilling capacity of 44 meters per hour, which is an excellent result considering the extremely hard iron ore rock.
In the Mongolian province of Selenge, near the Russian border, there is a rough, dry, steppe climate with temperatures ranging from -30°C in January to +25°C in July, which in turn places heavy demands on man and machine.
Drolshagen - With the introduction of the new HBM 160, HAUSHERR now offers a pioneering alternative among blast hole drilling machinery in the medium size range. Designed for use in all types of coal and ore mines, the HBM 160 sets new benchmarks in its class thanks to its especially sturdy design and numerous innovative details. The machine manufactured in the Drolshagen plant is suitable for both rotary drilling and DTH applications with various low-pressure or high-pressure compressors in the diameter range from 153 to about 203 mm (6 - ± 8 Inch). The application weight is about 41,500 kg, depending on version and design.
A new, modern control concept makes operation easier while simplifying monitoring and fault diagnosis. The operating and service display can be used to select and show the machine status, operating information or fault messages. A diagnosis is now extensively possible without measuring equipment or specific technical expertise. The use of fewer components overall makes the complete system essentially failure-proof, while enabling diagnosis and thereby ensuring a high level of availability.
The rotary drilling variant of the HBM 160 is equipped with a single-stage screw compressor, this supplying 35 m³/min. (1235 cfm) at 7 bar (100 psi). The machine is powered by a Caterpillar C 15 diesel engine with 403 kW. Various high-pressure compressors are also available for DTH use with max. 36 m³/min. (1270 cfm) at up to 30 bar (435 psi). Diesel engines of various sizes are optionally available in line with TIER 3 or TIER 4f.
The drill rig is infinitely adjustable and lockable between 90° and 60°. The chain feed enables a maximum contact pressure of about 170 kN (37,500 lb bit load) onto the drilling tool along with a return force of 160 kN. In conjunction with the high torque of the drilling drive, this enables high drill performances and minimises the risk of rod or tool losses. The machine has a hydraulic pressure control for DTH operation. This allows the contact pressure to be adjusted precisely to the requirements of the relevant hammer. 6 drilling rods with a length of 9 m each are housed in the revolving magazine, normally with a diameter of 127 (5“) or 140 mm (5 ½“). The maximum drilling depth is therefore 63 m when using 7 rods.
Like all HAUSHERR machines, the different components are protected from unauthorised access and the effects of the weather by lockable cover hoods. The central walkway along with a walkway on the cab side ensure that all components are easily accessible for maintenance or repair purposes. By eliminating the need to disassemble other components, unnecessary complications are effectively avoided.
A special highlight is the newly developed FOPS cab, this setting new standards when it comes to safety, ergonomics, space-saving and user-friendliness. All operating elements for the main functions are integrated in the new multifunction joysticks and in the armrests of the air-sprung and heated driver's seat. This can be rotated by 270° for entry and for driving or drilling operation, so that all operating and monitoring instruments can always be reached and read by the operator from a comfortable sitting position. Sound insulation features reduce the noise level inside the cab to less than 80 dB(A). Extensive safety glazing with tinted, heat-insulated panes ensures tremendous all-round vision of the entire working environment in every situation. The work field can also be illuminated optimally by diverse LED headlights in the dark. Cab heating, trace heating, air-conditioning and sun blinds make sure that the working conditions always remain pleasant whatever the weather conditions. A large roof window with wipers and wash system now enables an even better view of the rig tip. The heated windows at the front, sides and roof are also new, which means fogging will be a thing of the past. These are also freed of ice in just a few minutes in winter thanks to a thawing function. A ventilation system also ensures a continuous overpressure in the cab, this preventing potential penetration by harmful fine dusts. A sturdy sliding door with latching function reliably prevents unintentional slamming - by the wind for example - thereby averting accidents and injuries.
The sturdy caterpillar tracks are connected to the vehicle above via a ball-bearing slewing ring. The machine can therefore swivel by 90° to the drive of travel. This is a unique advantage when drilling sloped blast holes, as it shortens the unproductive travel routes and hence times between drilling by up to 50 %. The support and alignment is designed using 4 stable support cylinders with large base plates.
The machine comes with a dust removal system as standard. This has water-insensitive and abrasion-proof filter elements whose service life can be up to 10,000 hours. The machine can optionally be equipped with a water-injection system for dust suppression.
The machine can also be provided with an extensive Arctic package for use in cold regions. This comprises a combination of various heating systems along with a special clutch, these allowing the diesel engine to start fully free of load. Especially powerful batteries suitable for low temperatures, an additional starter, as well as the intelligent clutch control therefore make it easy to start the preheated diesel engine without any problem. The risk of brittle fracture in structural components due to low temperatures is countered by selecting suitable materials and by using special welding fillers. The use of fuels and lubricants suitable for use at low temperatures rounds off the package. Diverse adaptations can also be made for use at heights of 2,500 m and more above sea level. These include various optimisations to the compressor as well as the choice of a powerful diesel engine in order to compensate the power losses resulting from high altitudes.
The HBM 160 can be customised to the needs of the application thanks to a wide variety of extra options. Thus trace heating, central lubrication, joint lubrication, drilling data systems, GPS systems, preparation for fast-fuelling facilities, video systems, automatic fire-extinguishing installations and much more are available.
With the new HBM 160, HAUSHERR now offers a genuine alternative with a wide range of unique advantages over competitor machines otherwise only manufactured in the USA or China. You can find more information and contacts at: www.hausherr.com.
