IT’S ALL ABOUT EVERYONE’S HEALTHHelping you to ensure a safer workplace and healthier workforce is of the utmost importance to us. The wellbeing of any person coming into contact with our equipment is paramount. Therefore, we strive to identify and assess potential risk factors that could threaten the health of you and your employees. All products in this catalogue are designed to meet safety requirements.

BE AWARE OF ALL SAFETY PROCEDURESWe ask that you start by obeying all instructions given. Never work under an unsupported roof or close to potential pinch point locations. Beware of the potential hazards of a loose roof and ribs, and scale down roof and ribs prior to bolting. It is important to bolt early in the mining process – as soon as is safely and practically possible. Safe work procedures should incorporate inspection – before the machine operates, and also through regular monitoring based upon mining conditions, safety and hazard management systems. Workers should be provided with safety information, instruction and training on transportation, installation, operational care and disposal of drilling tools.

The mining industry continues to demand even higher levels of safety and productivity. In order to meet these requirements, we work continuously to develop safer products, and to produce comprehensive manuals on the safe and effective use of our products.

DRESS RIGHT FROM HEAD TO TOEYou must wear appropriate personal protective equipment (PPE) at all times. This is what we strongly recommend to help avoid injury:

– Safety helmet – Hearing protection – Safety glasses – Protective, high visibility clothing – Respiratory protection – Safety boots – Any site-specific PPE as required

MAKE A RISK ANALYSIS BEFORE YOU STARTPay attention to safety when planning all of your work. Before you start, always take the time to go through all operations. Identify any potential risks and take appropriate measures to avoid them. If necessary, seek expert advice on how to help minimize risks. Finally, make sure that you have the right resources to perform all tasks in the safest manner possible.

PUTTING YOUR SAFETY FIRST

“TAKE FIVE” TO IDENTIFY HAZARDS A great safety tool to use before you start working is our app “Sandvik Mining Take Five”. The app consists of a simple, step-by-step checklist with five questions that you should ask yourself to identify potential hazards. The app is free to download for smartphones and tablets, both on the App Store and Google Play.



LIFTING PROCEDURESUse the correct safe lifting practices when working with heavy items. Consider your body position, the awkwardness of the item, and its weight. Are two people required for the job, or is a lifting device needed?

STRAPPINGRods are bundled up with strapping. Take extra care when cutting this strapping. Personal injuries can occur in this situation.

INSTALLATION/REPLACING WORN BITSCemented tungsten carbide tipped bits have tough, wear-resistant edges. These can fracture or cause hard objects, such as steel hammers, to chip when struck during the installation or removal process. The use of the correct hand tools is strongly recommended. New bits should be screwed down tightly by hand. Do not use the rotation of the drill rig to install the bits.

EXTENSION DRILLINGExtension drilling poses potential hazards. There is a risk of crush injury during the guidance of one drill rod onto another. Correct uncoupling procedures must be utilized. The use of the correct hand or machine tool to uncouple the bottom rod from the drill string is recommended. Striking or bending the rods to facilitate uncoupling is not permitted.

MESH ENTANGLEMENTTwo wing bits can become entangled in steel mesh. Do not use drill bits and rods as mesh alignment devices. They are only to be used for the intended purposes. Drill bit designs that reduce the risk of mesh entanglement are available.

GRINDINGOur rock tools have drill bits with cemented carbide tips. Cemented carbide is made up of tungsten carbide and cobalt. The grinding of these tips will produce hazardous substances and particles. These can be inhaled, swallowed or come in contact with the skin or eyes. Wear protective gloves, protective clothing and eye protection. In case of inadequate ventilation, wear respiratory protection. Avoid dry grinding in particular.

DEALING WITH WORN PARTSWorn parts should be removed and disposed of appropriately. Your used tools can be recycled. Please contact your local Sandvik Mining representative for support and further information about how to recycle tools.

STORINGAll products should be stored in a dry place and in the original packaging until they are required for use.

HOW TO WORK WITH SAFETY IN MIND


USE – Do not come into contact with any rotating components. This is to reduce the risk of entanglement.

– Personal protective equipment such as eye protection and suitable clothing should be worn around machinery using carbide tipped drill bits.

– The drilling of rock will generate dust. Some dust is hazardous if inhaled. The use of water flushing or vacuum dust collection, and suitable PPE, is recommended.

– Drilling also generates noise. Recommended hearing protection must be worn.

– The drilling of rock, especially pyrites and sandstone, can generate heat that may ignite methane in the mine, which can potentially lead to an explosion. A blocked, blunt, worn, bent, cracked or damaged drill bit or rod can significantly increase the risk of frictional ignition, and must be replaced immediately. In particular, an insufficient supply of cooling water can lead to the ignition of methane. Safe work and operational procedures must include an inspection of the drilling bit and rod before use. Regular monitoring and reviewing should be carried out, based upon mining conditions, mine health and safety management systems requirements, and hazard management plans. Workers must be provided with safety information: instruction and training on transportation, installation, operational care and use, service and maintenance, as well as the removal of drill bits and rods.

– During positioning of the drill bit and rod, prior to drilling, there is a risk that the column strength of the drill rod can be exceeded. This can cause the rod to buckle, and pin a hand against the wall or rig. Approach pressures should be adjusted so that the columnar buckling load of the exposed length of drill rod is not exceeded. During drilling, proper balance between thrust and rotation must be maintained. For each drill rod system, refer to specific technical bulletins for the recommended operational requirements and thrust loading diagrams. A bent or broken rod must not be used.

– During drilling, the rod may be ejected from the drill chuck. Please utilize “twist locking” chucks where available.

– Inspect drill bits and rods before use and at regular intervals. If they are loose, blocked, dull, bent, cracked, burred, or otherwise unsuitable, DO NOT USE THEM! Replace them. Beware of the risk of creating a spark by incorrect removal methods.

– Correct storage of drilling consumables when they are not in use is important. Rods, in particular, can get caught on moving machinery.

By using newly-developed manufacturing techniques, our new generation of cemented carbide has greater density and a more homogenous structure. This has resulted in increased toughness without compromising the exceedingly high wear resistance – making the material stronger, without sacrificing its hardness.


Environmental considerations are crucial in all of our operations, and never more so than when it comes to the recycling of cemented carbide.

The global shortage of raw material has inspired us to create an extensive scrap-recycling program. We recognize today’s increasing environmental concerns and we are the only mining company that recycles both steel and cemented carbide. In fact, we have been collecting and recycling both scrap and discarded drilling consumables for conversion back into basic raw materials for almost 10 years. A large number of customers have joined our recycling program during this period. One major reason for this is that we make it easy for them to recycle, by collecting scrap from their own premises. Our recycling plant in Chiplun, India complies with the most stringent environmental standards, and is certified to the ISO 14001 and OHSAS 18001 (ISO 45001) international standard.

RECYCLING THAT PAYS OFF FOR YOU

TRANSPORTATION AND STORAGEDuring transportation, bits and cemented carbide components must be carefully packed in order to prevent damage to the cemented carbide. Even though cemented carbide is very resistant to impact against other materials, it is easily damaged by collisions with other components made from the same material.

MACHINE SETTINGS AND PRACTICESCorrect machine settings and good drilling practices are important factors in the service life of your drilling tools. Good management and maintenance also play a crucial role for your productivity and profitability.

PROPER CARE MEANS EFFICIENT OPERATION


Drilling is at the very heart of the mine: it is critical that every consideration is given to using products that ensure high quality and high reliability. Developments in underground mining point towards increased productivity and operator safety, which make drilling performance more important then ever. In this context, our range of drilling tools provides a perfect system. With satisfactory results achieved, it should be seen as your first choice.

REAL POWER WHEN YOU NEED IT THE MOST

DRILL BITSOur drill bits use unique carbide grades developed through years of experience and testing. Drill bit bodies make use of precision hardenedNickel Molybdenum steel and compound curve body designs, in order to maximize both cutting efficiency and excellent removal of cuttings. Our drill bits provide perfect cutting capabilities – for any application, in all drilling conditions.

DRILL RODSOur drill rods are manufactured from high strength alloy steel and are available in either hexagonal or round forms. The drive ends are fully forged, and the drill rods are heat treated for maximum durability and safety.Drill rods are available in varying lengths and designed for use on hydraulic rigs fitted to continuous miners, miner bolters and mobile drill rig machines.

ACCESSORIESWe manufacture and supply a comprehensive range of drilling accessories which are suitable for use in the installation of strata support products. These accessories include special spanners for the safe and efficient installation of rock bolts, and drill chuck extension spanners, which allow you to adapt your existing equipment to the rapidly-changing underground mining environment.

EXTENSION DRILLING SYSTEMSWe manufacture a complete range of extension drilling systems – both conventional, and direct drive. Every part is manufactured from high strength alloy steel and suitable for the installation of secondary support strata control products. Our patented Direct Drive Extension Drilling System is far superior to conventional drilling systems for four important reasons: it’s safer, faster, easier and smarter.


STATE-OF-THE-ART MINER BOLTERSandvik MB series bolter miners are electrically powered, track-mounted continuous mining machines designed to excavate roadways and install roof bolts simultaneously. They are safe, efficient, high-capacity solutions, suitable for rapid entry developments in long wall mining, and full-scale production in room-and-pillar mining. Since the cutter drum is mounted on a hydraulically actuated sliding frame, it is able to sump into the face independently of the mainframe and tracks. Since the roof and rib bolters are mounted on the stationary mainframe, they can be operated throughout the cutting cycle.

FLAMEPROOF MOBILE BOLTERFlameproof (FLP) roof bolters are specifically designed for coal mining applications, to meet special flameproof requirements. We provide FLP 4/6 head mobile bolters, FLP twin boom mobile bolters and long wall face bolters.

With maintenance and LCC in mind, a new roof bolter design provides a new level of serviceability. The roof bolter is designed for strata support and is machine mounted. With features such as stainless steel wear inserts and a fully upgraded drill head, the new roof bolter provides operators with increased reliability and serviceability. Modular and strategic design considerations mean that it is now easier to repair and service drill rig components on site.


Our drill bits are fitted with our own cemented carbide tips, offering superior life and drilling productivity. The bit bodies are manufactured in one-piece cast Nickel Molybdenum steel, and also feature optimized bit design geometry to ensure efficient and consistent drilling performance. The drill bits are available in sizes ranging from 27 mm diameter to 72 mm diameter, to best accommodate the varying requirements of strata support installation in underground coalmines.

EXPLORE SUPERIOR DRILLING PERFORMANCE


DRILL BITSOur drill bits use unique carbide grades developed through years of experience and testing. We use the most appropriate grade in combination with concentric and eccentric geometries, along with positive and negative rake angles, to provide differing drilling capabilities for any application. Drill bit bodies utilise compound curve designs to maximise cutting efficiencies and cuttings removal.

OPERATIONAL REQUIREMENTS: – Drill motor speed ≤ 650 rpm – Flushing water pressure ≤ 25 bar – Rotational torque ≤ 350 Nm

BUCKLING LOADSThe critical buckling load is shown for each rod section. Euler’s formula is used to calculate the critical buckling load, with a K factor of 0.7 (the drive end is assumed to be fixed and the bit end is assumed to be pinned; this simulates the end conditions when collaring a hole from a rigid machine mounted drill rig).
