Down-the-hole drilling tools

Blasthole drilling

Production drilling of blastholes in quarries and mines.

There are four main types of blastholes:

• Production holes
• Pre-split holes
• Buffer holes
• Production holes underground

Well drilling

There are two main purposes for well drilling:

• Waterwells
• Geothermal wells

The required depth and size of the wells varies geographically due to pump standards and geology.

Deep hole drilling

• Oil & Gas drilling is done to great depth. Normally 1000m or deeper.
• The well design determines what tools can be used.
• The wells are cased so casing systems are required.
• The wells are telescoped so a number of hammer and bit sizes are used.

Construction

There are a number of sub applications within construction which are:

• Piling & micropiling
• Foundation drilling
• Enviromental survey holes
• Blast holes

Exploration

• Exploration drilling is a deep hole application where the purpose is to collect the cuttings for analyses.
• Exploration drilling is in most cases done in remote areas far from normal infrastructure.
• Greenfield – focuses on finding minerals in previously unexplored areas.
• Brownfield - done within the mining properties or close proximity.

In-pit grade control

• In-pit grade control is done within mines to control the grade of ore that is mined so it can be mixed optimally to the refining plant.
• In-pit grade control is done so the mine more exactly can plan production and increase productivity.

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.

Down-the-hole bits

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 – High quality for high performance

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.

Reverse circulation – we offer a complete drillstring

Our reverse circulation hammers are specifically designed for all kinds of exploration drilling (deep hole and in-pit grade control applications). Whether you are exploring potential sites or working an existing mine, the Secoroc RC hammer will guarantee high performance, exceptional reliability and dependable support.

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.
