Rubber-type rotary blast-hole drills

HAFE is able to offer a range of rubber-type rotary blast-hole drills

Rock drilling surface crawlers

Our range of surface crawlers raises the quality of rock drilling to a new level. The lowest cost per tonne of rock produced comes from the higher productivity, straighter holes and the better overall economy designed into the range. These surface crawlers include several models that are ideally suited for bench drilling.

Choose between hydraulic top-hammer, or down-the-hole (DTH) drilling methods. The unique Rig will help you to drill smarter holes with high shift capacity, low energy consumption and innovative modules that improve productivity. Our range of crawlers is setting new standards for stability, maneuverability and safety in quarries and contracting work.

Tophammer drilling method

The classic tophammer method is renowned for high penetration rates in good drilling conditions. Exhaustive research into how impact energy can be transmitted into the drill bit in the most efficient way, with least possible stress, has resulted in a new generation of rock drills.

Development has been focused on the key component in the rock drill - the piston. The piston length, mass, and geometry have resulted in even faster penetration. The effect is that more rock is crushed with each blow from the piston.

Moreover, a double-damping system reduces the load on components leading to long service life and reduced drill steel wear. In other words, the positive results of faster drilling are not counteracted by higher drill steel costs. An extractor unit is also available for poor rock conditions.

Coprod drilling system

The coprod system combines the speed of tophammer drilling with the precision and long service life of the down-the-hole method. Inside each rigid, threaded tube section is an impact rod which is furnished with stop lugs to hold it in place inside the tube.

The so-called coprod sections are joined together via the other tubes. Since the other tubes transmit rotation torque and feed force only, the stress to the threads is minimal and life length is very long. All negative effects of transmitting the impact energy through the threads are eliminated entirely. The result is high-impact power with minimal wear.

Since the outer tubes are smooth and flush along the entire length of the drillstring, it is almost impossible for jamming to occur. Practical experience with coprod has been exceptionally good. The method gives good overall economy, particularly in large-scale production drilling and drilling in broken rock or other demanding rock conditions.

Down-the-hole (DTH) drilling method

Drills using the DTH method are easy to operate and maintain. The method offers a reliable way to drill hard to soft, solid to fissured or fracture rock, and features a hammer piston, which strikes the drill bit with virtually no power loss.

Shallow, deep or long holes are drilled with barely any change in capacity and hammer casing and stiff drill tubes offer good guidance for the hammer and drill bit, minimising in-hole deviation. Thus, blasting patterns and use of explosives can be optimised, increasing the yield of rock at a reduced cost per meter or footage drilled. The optimized annulus between the drill tubes and the hole wall ensures efficient hole cleaning under most rock conditions, including long or deep holes or holes filled with water.

HAFE's BlastDeck Plug - Reducing flyrock, vibrations, drilling costs, and the volume of explosives used in mining projects

The company's most popular product, the HAFE's BlastDeck Plug, offers dramatic reductions in flyrock, vibration, drilling costs, and the volume of explosives used in mining projects. It is widely used across all sectors of the mining industry.

HAFE's BlastDeck users have also observed increases in fragmentation and cast percentages while maintaining or lowering their powder factor. No auxiliary equipment, large cHafetal expense or changes in blast design are required.

HAFE's BlastDeck system for blasting operations and casting applications

The HAFE's BlastDeck system is made possible by the arrangement of a Power Plug, air and mass strategically placed within a borehole to improve blast results and dramatically decrease blasting costs.

Results in previous mining projects have shown the system is capable of removing the need for 10%-50% of explosives, reducing vibrations by up to 75% and most impressively, completely eliminating air blast and fly rock. And despite reducing explosive consumption, the fragmentation distribution remains unchanged or is actually improved in some operations, while reducing the undesirable fines content in others.

It has also been proven that by focusing most of the blast energy in a downward direction, single and multiple HAFE's BlastDeck designs can greatly increase control. In many cases, stemming length can be reduced without increasing the danger of fly rock. Sub-drill can be reduced by up to 100%, and in casting applications the throw volume is significantly increased.

Remote firing devices for surface and underground mining

A specialist in remote firing devices (RFD), HAFE's BlastDeck provides cost-effective blasting solutions from premier manufacturers. Systems can operate either on the surface or underground and provide superior performance.
