Rock Drilling
General rock drilling services can be done with a wide variety of different sized rigs. A frame-mounted machine is commonly used when drilling non-reinforced concrete or brickwork. Percussion and rock drilling use a hammer action technique which vibrates the material loose with steel or tungsten carbide tips, clearing the hole as it proceeds.
The small drills are commonly used for dowel bar insertion and resin anchors, due to the rough side walls that are left once drilled. They are preferred by engineers as the roughened surfaces provide a key for resins and compendious grouts. With the larger machines, the access and ground conditions dictate the drilling system to be used. Typical options include Down-The-Hole (DTH), hammer, Overburden Drilling Systems (ODS), flight auger and Duplex systems.
For smaller diameters, restricted access and shorter anchorages, the bespoke compact drifter rigs are ideally suited. We use the wide selection of drills available for such diverse operations as drilling through rock and mass material to the drilling of tap holes on blast furnaces without the use of water flushing.
Diamond Drilling
Throughout the past 20 years, we have undertaken some of the most difficult drilling operations for US giant UCAR in all parts of China, bringing our expertise to the most complex operations. When you require diamond drilling in Yorkshire, you need an expert company who deliver outstanding results on every job they complete.
With no dust or vibration we create clean, accurate holes with diameters of between 8mm to more than 1500mm which can be vertical or horizontal, depending on the requirement.
Due to its versatility it can be deployed on virtually any material including glass, metal, stone, asphalt and tile. It can be utilised in any situation where precise holes are required, such as creating large openings for ducts, smaller holes for pipes or wiring and creating holes for the placement or anchoring bolts.
Stitch Drilling
Stitch drilling is a commonly used method of forming holes where the size or shape is abnormal. This method entails a series of holes to be drilled next to each other to form the opening. This method can also be used for holes over 1.0m diameter.
Drill motors vary in size and can be attached to various types of rigs, all of which can be powered by various means: air, electric, petrol, or diesel. A common drill rig set-up would be a static column with an electric motor attached, mainly used for drilling cores up to 250mm diameter. Thereafter a hydraulic motor would be used as this provides the correct peripheral speed and torch, which is required for the larger diameter cores.
Different attachments range from trailer mounted rigs, hand-held drill motors, twin column assemblies, and automated rigs, all of which are used and specified to suit all drilling environments. Having the right drill rig and set-up can be the difference between a successful and non-successful operation being carried out.
Condor Projects completed the drilling of the two tap holes at Port Talbot for Tata Steel (Tata) over a two day working period on 30th January 2012. Using the bespoke Tamrock Drilling Rig coupled with our extensive previous experience in this field enable the project to be completed by the end of the weekend and in line with Tata's requirements.
