Characteristics of Underground Jumbo Drilling Rig
Robust Build: Underground jumbo drills are built to be strong and tough, so they can handle the tough conditions in underground mining. They use heavy-duty materials, which makes them last a long time and work well even in difficult environments.
Powerful Drilling: These machines have robust hydraulic or pneumatic drilling arms that can easily drill into various types of rock.
Versatility: Jumbo drills are versatile machines because they come in various sizes and configurations. This means they can be used for many different types of mining operations and tunnels.
Operator Comfort: Manufacturers put a lot of emphasis on making sure the operators of these drilling machines feel comfortable and safe. They do this by adding easy-to-use controls and cabins with air conditioning.
Automation and Remote Control: Certain modern jumbo drills have automated functions and can be controlled from a distance. This reduces the need for humans to be in dangerous areas during mining operations.
Functional Configuration
This Jumbo drill machine is Equipped with an environment-friendly diesel engine to drive traveling and positioning, an electrical motor to drive drilling operation, the dual power configuration allows the rig for fast maneuverability and zero-emission with a very low noise level of the drilling operation. The rig is also equipped with high efficient hydraulic drifter and heavy-duty floating and steady combo boom drilling system, with high accurate automatic horizontal positioning and 360 rotating function, which allows the rig to finish 35 m2 face drilling coverage in one operation and also can be used for bolting and many other applications.
Applications of Underground Drill Rigs
Underground drill rigs find extensive applications in several industries, including:
Mining Operations
These drill rigs are crucial for extracting minerals, ores, and other valuable resources from beneath the Earth's surface. They play a pivotal role in the exploration and development of underground mines.
Construction Projects
In construction, underground drill rigs are utilized for creating foundations, tunnels, and other subterranean structures. Their ability to drill in confined spaces makes them indispensable for urban construction projects.
Geotechnical Exploration
Geotechnical engineers use underground drill rigs to collect soil and rock samples for analyzing subsurface conditions. This information is crucial for designing safe and stable structures.
Types of underground drilling rigs
Jumbo Drills
These are large rigs used for creating multiple blast holes at once in hard rock mining operations. They typically have several drill arms and can be highly automated.
Longhole Drills
Used for long hole drilling, which is a method of drilling deep holes (often up to 60 meters) for blasting.
