Production drilling of blastholes in quarries and mines.
There are four main types of blastholes:
There are two main purposes for well drilling:
The required depth and size of the wells varies geographically due to pump standards and geology.
There are a number of sub applications within construction which are:
Down-the-hole hammers – when proven technology is required
Our hammers are purpose-matched for all rock types and applications. Choosing the right hammer is largely determined by hole size and type of rock formation. Ideally, the size of the hammer should match the required hole dimension as closely as possible, leaving just enough space for cuttings to evacuate the hole.
We offer a comprehensive range of DTH drill bits to match all conceivable applications. Each bit is made from quality alloy steel, and has been precision machined to produce a perfect body, heat treated to the required hardness, given surface compression for fatigue resistance, and fitted with precision buttons manufactured in-house.
Down-the-hole pipes and adapters
Key features of a high quality DTH pipe are durability, accuracy and manageability. Our pipes are made from cold drawn piping, providing a superior surface finish and tolerance compared to conventional pipes made from hot rolled piping.
Accessories and parts
We provide high quality spare parts and accessories to all our products. This is essential to guarantee maximum output and low lifecycle cost. All Epiroc Customer Centers and their network of distributors offer a complete range of spare parts and accessories. The staff is trained to support with advice and technical assistance to get the right part for every application. Only genuine parts can handle the stress that an Epiroc product causes on its components. And only original parts enable the owner to minimize downtime, to protect their investment and to contribute to productivity of your company.
Breakout bench – Handy but powerful
The threaded connections of the driver chuck and the top sub may become very tightly tensioned during drilling. It is convenient to break the hammer threads on the rig, but if the threads cannot be loosened or tend to get stuck, a breakout bench is the solution. This handy but powerful breakout bench can easily be placed in a workshop or container and it breaks DTH hammers between 3 – 8" in the standard version or 5 – 12" in the heavy duty version.
