Rock drilling equipment includes a wide range of tools and technology designed to penetrate rock formations where traditional methods are ineffective. The primary function is to create holes in the hard abrasive surfaces that allow mining, exploration, and construction operations to happen. Rising demand for mineral resources, growing urbanization, and new infrastructure projects have consequently created growth opportunities for the rock drilling equipment market. However, with a myriad of advanced and sophisticated tools available, choosing the fittest equipment requires mindful evaluations.

Here are 7 factors to consider before investing in rock drilling equipment.

1. Project Requirements

Whether it is a large-diameter drilling or micropile tieback, identifying the project and its needs is the topmost priority. The next important aspect is the scale or size of the project. If it is a project with a longer duration, it is going to require more robust, and durable tools than small projects. In addition, it is crucial to identify the solid type. Analyzing the ground condition, whether it is made up of clay, sand, or rock, and to what percentage, presence of ground waters, etc. influences the kind of drilling techniques, and equipment needed. The diameter and depth of the foundation are other dictating factors that should be considered. With deeper foundations, equipment capable of reaching greater depths is necessary.

2. Tool Compatibility

Ensuring the chosen tool with the previously hoarded equipment is required for seamless functioning on site. If a tool doesn&#;t fit in with the equipment the quality of the drilling degrades. Companies like Tianhe provide comprehensive understanding of various drilling rigs and offer expert guidance on selecting compatible tools to avoid downtime caused by incompatible equipment and effectively maximize utilization.

3. Equipment Size and Rig

To select the size and rig of the equipment, the first thing that needs to be considered is the condition of drilling. Choosing the size and rig hugely depends on whether mobility is the key or the topology where the drilling will be done. Drilling on a slope, or vertical rock wall, or straight down, each type of ground has a unique requirement. Moreover, the need for units is also to be taken care of. Whether you want a separate compressor or everything in one unit is a deciding factor indeed. Pantera TM DP, Ranger TM DX, and Dino TM DC are some of the leading companies that offer a series of drillers with an impressive range of hole diameters, power, and flushing air capacity.

4. Quality of the Equipment

Rock drilling projects are usually medium or long-term. Having high-quality equipment reduces unwanted time wasted on repairing, fixing, or replacing the tools. Using high-quality materials to manufacture drilling tools ensures their longevity and reliability. The durability and performance of a drilling tool depend largely on the materials used in its construction. It is necessary to choose companies capable of guaranteeing quality and durability. For instance, OCMA DrillTech provides an ISO: certification which is a recognized global standard for a cost effective, reliable performance and service life.

5. Depth and Diameter of Holes

The depth and diameter of the holes needed to drill are crucial considerations when choosing a drilling tool. Whether you are working on a large-scale mining project or conducting precise geotechnical drilling, the quality of the hole depends on the quality of the tools used for drilling. The right tool allows optimal drilling parameters, such as rotation speed and weight on the bit, which can reduce energy consumption and drilling fluid costs.

6. Cost-efficiency and Performance

Balancing initial costs with long-term benefits is an important aspect when choosing the equipment. With advanced technology and superior materials, these tools enable you to work faster without compromising quality, ultimately maximizing your efficiency and productivity on site.

7. Safety and Reliability

Buying the wrong tool often leads to equipment failure, stuck pipes, and other safety hazards. The quality equipment can withstand specific pressures, stresses, and conditions. The right tool can help maintain borehole integrity, preventing costly issues like collapsed wells. Proper selection allows for better control over the drilling process, reducing the risk of equipment failure and potential blowouts.

Last but Never the Least!

Last but never the least it is always a great option to ask for and consider references from previous buyers. If a company has a recognized track, it will have multiple testimonials from which you can get enough information about the equipment. Another point to consider is that the company should have a team of professionals and customer support services. Although choosing the correct equipment is a critical step for any dealing project, the selection process will eventually provide clarity towards making an informed and confident decision.

Rotary drilling: This type of drilling digs a hole by grinding the rock with a tool under the effect of weight and rotation. It is mainly used in oil production. The cuttings are brought to the surface under the pressure of a drilling fluid that is injected into the drill string. Drilling fluid also helps consolidate the walls of the borehole, so it is not necessary to case it as the operation progresses.

Down-the-hole drilling (rotary percussion drilling or rotary hammer drilling): this type of drilling uses drilling rigs that drill with a rotary cutter (drill head) and hammer the bottom of the hole with a pneumatic hammer. The excavated material rises to the surface under the pressure of the compressed air used for the hammer. These drilling rigs are powerful and have high drilling rates, especially in rock. For artesian wells (wells where water naturally rises to the surface under groundwater pressure) or geothermal drilling, an air injection at the end of the drill pipe pushes the water up the borehole, allowing the operator to immediately determine the water flow encountered. This type of drilling is used for hard and cracked ground up to 4,000 meters deep. When the drilling bit is eccentric, the drilling can be done with a casing advancement system (installation of tubes by gravity) which reinforces the hole as the drilling progresses.

Top hammer drilling: this type of drilling uses drilling rigs that also operate on a percussion system, but one that remains outside the borehole. They are mainly used for small diameter drilling, for example for mineral exploration or the installation of tie rods in rock. This system is used for shallow boreholes, as there can be significant deviation due to the structure of the ground drilled through. These drilling rigs can operate in any direction however.

Auger boring: This is a type of rotary drilling using a worm screw (the auger). This type of drilling is mainly used for unconsolidated clay or sand terrain. The excavated material is directly brought to the surface by the worm screw. For deep drilling, it may be necessary to regularly raise the auger to empty it of its excavated material.

Core drilling: Core drilling is similar to rotary drilling, but it uses a crown to extract a sample, called a core, inside the tool.

Percussion drilling: consists in breaking the rock by dropping a tool, the drill bit, by gravity. This type of drilling can only be used vertically. To prevent the borehole from collapsing, it is necessary to case it as it is drilled. The cuttings are reassembled as soon as they interfere with drilling by replacing the drill bit with a flap valve bailer. The flap valve bailer is a type of tube equipped with a tilting flap in the lower part. This tilting flap allows the tube to be filled with excavated material which is then transported to the surface.

Pipe jacking: is mainly used to install horizontal pipes. The tube is pushed progressively by percussion, the excavated material being removed at the end of the drilling operation either by water injection or with an auger. This technique is used in particular to avoid transmitting vibrations to the surrounding buildings or to avoid digging a trench.
