What is a Surface Drill?
A surface drill or drilling rig refers to a machine that creates holes in the ground. The rig operates at the ground level while the drill penetrates the earth's crust. You can use the machine to drill water wells, extract natural gas, install subsurface utilities, test geological features, and draw mineral deposits. Surface drill rigs come in different sizes – ranging from light manual devices operated by one person, to massive facilities.
What is the Drilling Process?
The process begins with choosing a suitable location and obtaining the necessary permit. Then, a qualified professional will come to the site with a drilling machine. In rotary drilling, for instance, a technician hooks the drill bit onto the pipe or drill spring. Then, the bit drills into the formation as it rotates. Meanwhile, the cuttings will be flushed out of the drill hole to the surface. A durable plastic pipe or steel casing is recommended to prevent a cave-in or contamination by surrounding elements.
Certain wells drilled into gravel operate under high flow rates. To prevent water from coming into contact with the gravel, installation of a good screen at the casing's bottom is a must. Then, the space between the casing and drill hole sides is filled with grout. This helps to block out contaminants that may seep into the well.
While surface drill rigs (for horizontal drilling) have an engine, pumping mechanism, hydraulic systems, and a structural frame, directional drilling rigs are movable and can be mounted on trailers and trucks. Depending on the diameter and length of the bore, engineers can use either light or heavy rigs. Light rigs can drill holes of up to 36 inches in diameter and 3,000 ft. in length. Heavy rigs can bore diameters of up to 60 inches and lengths of about 10,000 ft.

Types of Drilling Equipment
Choosing the best drill machine for industrial use is based on the type of technology it uses. The most popular drilling technologies include down-the-hole and top hammer drilling. Take a read.
In DOWN-THE-HOLE DRILLING, the rigs use a rotary cutter and pneumatic hammer. The materials are excavated to the surface through pressure created by compressed air. Thanks to their high power, down-the-hole rigs make an excellent rock drilling machine. They are also used in geothermal drilling and artesian wells, where water springs naturally due to groundwater pressure.
One of the top down-the-hole Sandvik drilling machines is a diesel-powered Leopard DI550. Most construction contractors trust the machine because of its smaller footprint and excellent mobility. Featuring a fixed boom, drill pipe changer, unobstructed component layout, and operator's cabin, the crawler-mounted rig is ideal for quarrying operations and DTH blast-hole drilling. Its 24.4 m³ compressor works at 24-bar pressure, while a 328kW diesel engine allows it to match perfectly with a 5" DTH hammer.
With optimal power utilization, Leopard DI550 saves energy and costs, making it one of the most economical drill rigs. Besides high productivity, the operator environment is top-notch, offering seamless interaction between man and machine. An automated system handles the controls while the operator takes care of drilling.
TOP HAMMER DRILLING is ideal for small-diameter drills. For example, setting up tie rods in rock and mineral extraction. It can also use the percussion system though outside the borehole. The rigs work in whichever direction, which is beneficial when there is a substantial variation in the ground being drilled. If you need a surface miner for construction projects, open-pit mines, or pre-spilt drilling in extensive quarries, check out Pantera DP1500i.
This diesel-powered hydraulic rig from Sandvik has the highest power in its class. With Pantera DP1500i, you can bore holes from 3.5 to 6 inches in diameter. As one of the latest generation rigs, it penetrates better and provides a wide array of data, e.g., the work done and the drill's condition. It features high-quality visibility, clever drilling parameter settings, and an advanced safety cabin (ROPS/FOPS certified). Expect more prodution hours, smooth operation, fuel economy, and true power.
Another benefit of the top hammer Pantera DP1500i is the ease of maintenance, thanks to a hassle-free component setup. A touchscreen interface facilitates convenient operation with new drilling functions, including troubleshooting options. The JW Bell experts can also customize your rig to meet special requirements for any project. From a surface miner for construction projects, open-pit mines, to pre-spilt drilling in extensive quarries, Pantera DP1500i is the rig you need.
TOP HAMMER DRILLING
Other Types of Drilling Technologies
a) Rotary Drilling
Rotary drilling utilizes a heavy rotating tool to grind rock. The application is most suited for oil production.
In this case, the excavated materials are moved to the ground top via fluid pressure inside the drill string. The drilling fluid reinforces the borehole walls, eliminating the need to case it while the machine is at work.
b) Auger boring
Auger drilling uses a corkscrew shaped bit to extract material from the ground.
While drilling, the auger drill bit screws into the soil, and material is automatically moved up the shaft of the rotating device.
c) Core Drilling
It utilizes the same concept of rotary drilling, but has an interior crown (core) for extracting a sample.
d) Pipe Jacking
This method is often used for the installation of horizontal pipes. In pipe jacking, the tube is gradually pushed by percussion.
In the end, the excavated materials are removed by an auger or water injection. This technique combats transmission vibrations that may affect the surrounding structures. It also eliminates the need for digging up trenches.
