Deilmann-Haniel Mining Systems GmbH

In 2012, all special mining activities of the former Deilmann-Haniel International were restructured and bundled under the roof of the Redpath Group based in North Bay, Ontario/Canada. As a result, Deilmann-Haniel became a 100 % subsidiary of Redpath Mining Inc. which is a wholly-owned subsidiary of ATON GmbH based in Munich/Germany. Since 2012, the affiliation to the Redpath Group was documented by adding “Member of the Redpath Group” to the Deilmann-Haniel company name.

After seven years now as member of the Redpath Group Deilmann-Haniel would like to bear the name of the world’s leading company in the field of “Mining Construction“ even directly in its name, and would like to preserve the more than 130 years of tradition of success of the “Deilmanner” at the same time. That’s why Deilmann-Haniel has renamed the company effective 1st October 2019 into REDPATH DEILMANN GmbH and will adopt the logo of the group as well as all other companies of the Redpath Group.

The new company name shows to all clients, partners, suppliers, and other stakeholders that the company is part of the world’s leading mining contracting group, which stands for satey, quality, reliability, innovation and efficiency. All other company data such as address, commercial register number, account data or VAT ID remain unchanged. The web address is www.redpathdeilmann.com since October 2019. (REDPATH DEILMANN/Si.)

On 7th July 2017, Deilmann-Haniel GmbH, Dortmund/Germany, entered into a contract with the Belarusian company Slavkaliy to build a new potash mine. The mine is planned to produce 2 mt/a of potassium salt and will be built in the Belarusian potash district, approximately 200 km south of the capital city of Minsk.

The commission involves drilling two shafts approximately 700 m deep with the aid of the ground freezing method, as well as creating numerous underground drifts for accessing the mineral deposit. The commission is worth over 200 m € and the building work will take just under five years to complete. The shafts will be drilled using the mechanised SBR (Shaft Boring Roadheader) system developed by Herrenknecht AG. It will be the first time that this system has ever been used in Europe. A total of around 250 workers will be working on the site, where the key works will be carried out by Deilmann-Haniel staff from Germany and Russia. Another 200 or so Belarusian workers will be recruited on site.

Deilmann-Haniel GmbH has been ope-rating as a specialist company for mining both within Germany and internationally for nearly 130 years. The company is a member of the Canadian Redpath Group and has subsidiaries on all five continents, making it one of the world’s leading businesses in the field of building work and special work for the mining industry. This major new order constitutes the next step in the successful implementation of the company’s growth strategy on the international mining markets. Furthermore, a similar shaft building project that Deilmann-Haniel has been carrying out in the Russian potash district in the Urals since 2012 is about to be completed – right on schedule – thus ensuring the continuing of activities in the Russian-speaking region.

Shaft sinking companies are showing an increasing interest in the use of shaft drill rigs equipped with high performance hydraulic rock drills. Therefore Deilmann-Haniel Mining Systems GmbH (dhms) has developed all-hydraulic shaft drill rigs with three or four drill booms now. The rigs are available in flameproof or non-flameproof version.

The first all-hydraulic shaft drill rig with four booms will be delivered to the China Coal Mine Construction Group Corporation (CCMCGC) in Hefei, Anhui province, China, in autumn 2015. It is planned for use during sinking of new shafts for development of new mines or mine extensions.

 

The new all-hydraulic shaft drill rig SDH4 provides a number of benefits compared to conventional pneumatic or semi-hydraulic versions regarding following aspects:

• increased drilling speed during blasthole drilling,
• increased drilling speed and drill depth during extension drilling (e.g. injection holes),
• simple and quick change between rotary or rotary percussive drilling mode and therefore easy adaption to varying rock conditions,
• improved drilling control (collaring, anti-jamming system),
• avoiding of lubrication oil mist,
• reduced noise level,
• reduced compressed-air consumption (compressed air is only needed for drifter lubrication or flushing).

The high drilling speed achieved by using hydraulic rock drills means that the rig can operate with fewer drill booms. Thus time for erecting at shaft bottom and number of operators can be reduced.

The drill feeds fitted to the new rig feature a cylinder system that delivers high thrust and pull-back forces. They also come with a hose reel and can be equipped with a hydraulic clamping device for extension drilling and a dust suction hood for air flushing. A choice of rock drills is available and clients can opt for the powerful dh DP15 drifters or rotary drills of the dh DR series. Rock drills can be changed with very little effort.

One or two tailor-made electro-hydraulic power packs are installed on the shaft platform to provide the drive energy. Special measures have been put in place to protect the power packs from water ingress. The drive station can be coupled to the drill rig after the latter has passed through the lower shaft platform and then uncoupled again for the return trip. The connections comprise two hydraulic pressure lines, one return line and one oil drain line plus the supply lines for flushing water or air. Zero-leakage hydraulic quick-couplers are used. The electrical connections comprise a power cable for the 24 V DC supply and a data transmission cable. Special connectors are used for the interconnection points, while control commands are sent from wireless remote controls. A separate console is provided for each drill boom and each control console can be switched over between the different booms.

Like the compressed-air equipment the rigs can be folded up umbrella-like for in-shaft transport and are designed for a maximum transport diameter of 1,900 mm.

After reaching the shaft bottom the SDH4 is positioned in the shaft center and braced by three struts to the shaft wall. Then the drill booms are brought into drilling position. To match uneven shaft floor conditions the tripod can be adjusted hydraulically.

In early 2015 Deilmann-Haniel Mining Systems GmbH (dhms) delivered one first roadheader dh R60t for roadway development at a new hard coal mine in Turkey. Two more roadheaders dh R75t followed in April and July 2015. All three machines have been ordered by Hema Energji Inc., an affiliate of Hattat Holding Enerji Group, which is building a new coal mine with three vertical shafts, called the “Amasra Hardcoal Project”, at the Black Sea Coast in northern Turkey. In a depth of approximately 700 m hard coal will be extracted mainly for a thermal power plant. It is the biggest new construction project in hard coal mining in Europe. The mine has a reported reserve of 573 mt.

Due to the challenging development conditions with rock strengths up to 120 MPa heavy powerful roadheading machines with low-heigth design are needed. Special characteristics of the chosen roadheaders are:

• onboard drilling and bolting device,
• telescopic cutting boom,
• low machine height,
• external water-mist sprays on the cutting head,
• automatic stabilisation system for improved stability during cutting,
• low floor pressure relative to the machine weight.

The low machine height ensures that the same equipment can be used to drive low-profile and high-profile roadways, such as main gates and tail gates, as well as arch-section and rectangular headings and coal face development headings with low roof heights.

Wide-based chassis and the resulting low floor pressure facilitate manoeuvring on soft roadway floors. The telescopic cutting boom also allows the cutting head to sump into the heading face, thereby reducing wear and tear on the machine chassis and helping to protect the roadway floor.

The integrated drilling and bolting system enables quick and accurate hole positioning every time. As well as conventional bolting positions in arch-section and rectangular roadways the drill feed can also move to any conceivable drilling angle in the drivage direction, as may be required for exploration and reinforcement work or additional blasting. High-performance hydraulic rotary drills from the dh DR series or the dh DP15 drifters ensure short drilling and bolting cycles no matter what bolting method, bolt length or bolt design will be applied.

The scope of delivery for each of the three roadheaders consists of one tailor made bridge belt conveyor system and a dedusting unit. For training of the local mine staff and to support the roadheading operations the machines will be accompanied by dhms technicians during the first four months.

In March 2015 Deilmann-Haniel Mining Systems GmbH (dhms) delivered a multi-purpose crawler named dh L2000d for backfilling operations to the German Company for the Construction and Operation of Repositories for Waste (Deutsche Gesellschaft zum Bau und Betrieb von Endlagern für Abfallstoffe mbH – DBE). This innovative crawler dozer with a weight of 28 t is used at the former iron ore mine Konrad located near Salzgitter in Lower Saxony, which is currently being prepared to become a repository for low and intermediate level nuclear waste with negligible heat generation.

The backfilling of underground roadways has to be done with close roof contact with a backfilling rate ≥ 95 %. Roadway inclination in backfilling areas added to the inclination of the muck pile is up to ± 25° (47 %). Based on the largest class of dhms side-dump loaders a low-profile multi-purpose crawler with a swiveling telescopic boom was developed especially for this task. It features a quick coupling device for change between dozer blade and side-dump bucket. The crawler tracks are equipped with 500 mm wide special base plates in order to achieve the necessary traction forces.

Plunger cylinders at the dozer blade ensure an adjustment of 20° to both sides and allow backfilling along the roadway axis with a swiveled boom (also 20° to both sides). So the roadway sides can easily be backfilled also when the crawler is moving along the roadway axis.

For mobile use the dh L2000d is equipped with a diesel hydraulic drive. The 4-cylinder in-line engine made by Perkins is equipped with turbocharger and charge air cooling. It has a total power of 129.4 kW at a speed of 2,200 rpm and meets the newest emissions guidelines Euro 4 (Europe) and EPA Tier 4 Final (US). The engine provides a maximum torque of 750 Nm at a speed of 1,400 rpm.

Operation of the crawler is achieved by joysticks and an electric pilot operated hydraulic system. The driver’s compartment (FOPS/ROPS) includes a LCD display showing all operating states and picture of rear camera. A central lubrication system facilitates maintenance operations. Fire prevention is ensured by an integrated fire extinguish system. The modular design of the multi-purpose crawler with mining appropriate transport dimensions enables a quick transport and a short installation time.
