Drilling and blasting operations are at the foundation of any mining project and in the last century was the only economical method of tunneling however with breakthrough in new technologies the option of Tunnel Boring Machines (TBM) has come into play although it is limited in its use due to its capital cost.
Shorter tunnels tend to be less economical to construct with a TBM and are therefore usually constructed by drill and blast. TBM’s use however is more in the construction of tunnels for road or rail infrastructure than in mining but as mines move towards greater mechanization their use will become more prevalent.
Today there are specialized contractors who carry out drilling and blasting in mines. They make use of hand drills to truck mounted drills which can be either hydraulic or pneumatic some of which are even purpose built for specific jobs.
Blasting on the other hand is also a highly specialised field because poor blasting can affect the economics of a mine not to mention putting the lives of miners themselves at greater risk.
Common explosives used in industry now are ANFO (ammonium nitrate/fuel oil), slurries, and emulsions. Many factors are taken into account when determining what type of blast design or explosive will be used. Rock type, density, and strength are all important factors, as well as fracture condition of the rock, and water conditions.

A new design of the piston dampening system creates less wear and breakage of shank adapters, drill steels, and drill bits.
Advantages are that a drilling operation is not tied to a single purpose machine that will not perform. When the host machine wears out or a new job requires a different operation, the drill attachment is mated with a machine of your choice and work continues.
TEI ROCK DRILLS
TEI Rock Drills is a privately held family business located in Montrose, Colorado USA. TEI manufactures specialized drilling equipment for the construction, tunneling and mining industries. All drilling equipment is manufactured in their facility using 5-axis CNC machines and also CNC grinding on the hardened drill parts. These products are exported worldwide through distributors and direct sales to contractors.
There are three main product groups at TEI Rock Drills: Drilling attachments, limited access drills and hydraulic drifters and rotary heads. All of these products are produced to fill niche markets in drilling. In this way TEI is a very specialized company with many unique solutions to drilling problems. Drilling attachments are mostly excavator-mounted drills. These drills are used for earth retention installing soil nails and tiebacks. The extra reach of the excavator allows for faster installation and broader coverage for earth retention in natural disasters and planned construction as well.
The electric limited access drills are used for foundation repair and specialized tunneling and mining. Because TEI is relatively small compared to other drill manufacturers they are able to produce these extremely specialized drills. Larger companies cannot make such small machines at a profit. In tunneling TEI electric drills are used to cut cross-paths, install roof bolts and advance small diameter tunnels. TEI holds international patents on their hydraulic drifters. A drifter is the rotary/percussion “head” that turns the drill steel and supplies percussion for rock drilling. This is a very specialized type of manufacturing that is only undertaken by fewer than ten companies worldwide.
This year at Bauma TEI will be introducing the latest addition to the drifter line. The new TE160 will be the shortest (420mm) hydraulic drifter built to supply almost 7 kW of percussion power. Look to TEI for innovative drilling solutions at stand number N815/2. During the 2013 Bauma TEI Rock Drills will display a new model in their line of patented hydraulic drifters. The TE160 is a very short (420mm) drifter that provides a high blow frequency (6500 BPM) with high torque (135 daNm). This combination makes the TE160 especially suited for drilling where low headroom or short space is a priority.
For underground roof bolting the TE160 is not only very compact but also supplies the required torque for setting roof bolts. The OEM market for mining equipment has been requesting a shorter drifter for many years. The construction industry also requires new drifters for limited access drilling; the TE160 is being used to install the popular hollow-bar micro piles in the repair old buildings and bridges. In both cases the TE160 provides more power in a much smaller package than was previously available. The TE160 is available with one or two rotation motors, and a percussion unit that delivers 7 kW of power. Whether mounted on a TEI Rock Drill excavator attachment or another manufacturers rig the TE160 fills a void that has existed in the manufacturing of hydraulic drifters.
HARDROCK MINING PRODUCTS LTD
For nearly two decades, Hardrock Mining Products has specialized in manufacturing twisted steel drill rods in its Sudbury, Canada facility. The company owns the largest twisting machine in the world, supplemented by a forge and several CNC mills/lathes. It can offer all configurations of twisted and straight drill rods (Left or Right rotation, hollow or solid) for hard rock, soft rock, coal, salt, gypsum and other applications. Most shank and coupling configurations are offered, including typical threads, squares, tapered, hexagon and customer-specified. Hardrock also supplies a wide variety of bits for all rock types, all of them fully compatible with twisted or straight rods.
The advantage of their twisted rods over straight rods are: positive and rapid removal of chippings, faster hole drilling (typically 4X faster than straight rods) straighter, cleaner holes, much greater working life (up to 6X the life of straight rods), lower rod inventory requirement, lower shipping and handling costs (fewer rods required), perfect for use in broken or unstable ground and rod/bit can be retrieved from a collapsed hole by simply “unscrewing” it.
They have been involved in supplying, as well as designing specialty drill steel products for customers on a worldwide basis in both hard and soft rock mining operations. Hardrock Mining Products manufactures specialty Auger Drill Steel products using Turbine and Diamond Section raw materials. They also manufacture traditional drill steel products to be used with Jackleg, Stoper and Jumbo drill rigs for the mining, quarrying, construction and civil engineering industries.

Larmee Equipment & Supply, Inc.
Larmee Equipment & Supply (LES) is a world leader in used and refurbished rock drilling machines for construction, quarry and mining. For the past 33-years it has offered refurbished machinery solutions at considerable savings.
LES is pleased to promote a new partnership between Junjin CSM of Seoul, South Korea and Larmee Equipment & Supply in Louisville, KENTUCKY-USA to form Junjin America as an alternative solution to refurbish.
LES offers rebuilt units, serviceand accessories for most makes and models of drills and compressors both new and old.
Drilling Accessories include: Mitsubishi, Boart, Brunner & Lay and many others.
With over 30 years of experience, LESis able to utilize their expertiseto perform complete hammer/ drifter rebuilds.
The primary reason why LES partnered with Junjin CSM was to fill the industry-wide need for a simple and easy to operate Rock Drill.The other Rock Drill choices in the marketare now too advanced and complicated to be serviced by owner/operators on a regular basis. LES brings a strong marketing and sales background into the partnership backed by the solid manufacturing and quality reputation of Junjin CSM, who is producing the drill.
The first product of the collaboration between Junjin CSM and LES is the Rock Commander line of drills.
Along with the increased production, environmental advantages, and ease of operation, the Rock Commander drill will be offered at a price far below the existing manufacturers in North America. In addition the Rock Commander’s sister drills are at work in Russia, Africa and the Middle East.
According to Joey Sexton, the marketing manager of LES, the company’s African market base is in Botswana, Ghana, Guinea, Kenya, Nigeria, Republic of Congo, South Africa, Tanzania, Uganda, and Zimbabwe.
He added that a developing trend in their industry is to introduce more high tech applications for what truly is a simple product. The Rock Commander produced for Junjin America defies this trend.
Thierry Bernard Technologie T.B.T.
With 22 years of experience in explosive engineering, blasting and mining industry worldwide, Thierry BERNARD lead TBT to promote DNA-Blast Technology for those who are looking for blasting performances and associated Return On Investment. DNA-Blast is primarily based on physics mechanism such as thermodynamic, detonics, rock mechanic, damage principles, ballistics and has been built along the last 20 years capitalizing on Dr.Thierry Bernard’s international field experience.
I-Blast is a unique 3D physics-based blast simulation software designed for mining engineers looking for optimizing blasts results without delaying the blasting process. I-Blast is “powered” by the DNA-Blast technology. I-Blast software delivers advanced analysis outputs to speed up the workflow and design more efficient blasts.
The company has already ventured into the African market with products in the South African iron ore mines, Gold mining in Mali and Mines in Morocco.
The unique feature of the software that makes it a favorite for miners is that the software is User-friendly: a 3 days course allows users to start using the I-Blast software efficiently. 3D environment and “blaster proof” ergonomic definitely help in the usage of the product
It is an all-in-one product. With this software, someone is able to design their shot, simulate the effect (vibration, noise, fragmentation, muckpile shape and cast) and optimize their loading and timing sequence. This software allows African miners to remain independent from their explosives provider, having their own optimization and engineering tool. They also take into consideration the remote location of African sites with a remote support via VPN connection.
The product can be customized in the sense that local geology and local explosives formulas can be entered in the software for more accurate simulation. Calibration of the model based on measured field outputs makes the output even more precise.
Philippe Dozolme, the Customer Support advised consumers to check whether the simulation outputs are/not biased by the software supplier. Process optimization has to come from an independent source, not from one of the supplier.
