Introduction
Suppose you own a team and are ready to commence your job as a mining expert. Great! Underground drilling is the most critical phenomenon. You have to ensure the safety of workers and get the highest efficiency.
Selection of the underground drill can be the crux of the matter. You need a machine focusing on rock formations, drilling depth, operational requirements, and long-term maintenance.
Do you want to know the tips for choosing the right underground drilling machine? This guide is for you where we will shower blessings in different underground drills and know the best project!!
Comparison of different models of drill rigs
Different models of drills come with various types and designs of drill rigs. Guess what? Their features and application scenarios are different. For example, we have the top five drill types.
Long hole Drills
Long-hole drills are famous for their deep and long-hole drilling applications, as well as their accurate blast holes in hard rock mining. They can drill up to 60 meters in depth.
Therefore, they are ideal for sublevel stopping and cut-and-fill.
The common usage includes ore body extraction and production drilling.
Jumbo Drills
If you want to tunnel in the mine, jumbo drills are the ideal choice. Why? Because they have a high precision and quality. Plus, they are used for drilling blast holes in drift and tunnel excavation.
Raise Boring Rigs
Do you have to do vertical and inclined shaft drilling? Look no further than the boring rigs add here. They are designed to drill large-diameter holes.
Diamond Core Drills
Diamond core drills are biopsy drills. They extract cylindrical core samples for mineral analysis and provide detailed geological data before mining begins.
The good news is that these drills can reach depths over 2,000 meters. If you want exploration drilling and geological sampling, go for these drills.
Percussion and Rotary Drills
Percussion and Rotary Drills are famous for their working mechanisms. They use either impact (percussion) or continuous rotation to break through rock.
Such drills are best for soft rock mining and coal mining.
Key considerations
The selection of the right drill depends on various factors. But if you opt for a specific type, go for the following options:
Borehole Diameter & Depth
Borehole diameter and depth matter a lot. Some drills create longer and wider holes. They are ideal for ventilation purposes and create the ultimate support for further drilling. On the other hand, some drills create smaller holes and are often useful for the exploration and analysis of the soil.
Based on your needs, you have to select the borehole diameter and depth. Consider the compatible applications and tools.
Number of drill arms
Which drill machine are you using? A single-arm drill is different from a multi-arm.
But both of them feature a lot of different features. A single-arm drill is compact and useful if you have a small-scale mining operation in a limited space.
If you want large-scale mining with better efficiency, you can go for the multi-arm drills. But they need more space for the operations. So, consider the drill arms based on your needs.
Operational flexibility
Operational flexibility is the next-level approach toward the underground drill. Operational flexibility comes built-in with various drilling machines. For example, adjustable boom angles offer functionality in multiple directions.
Automation and safety control ensures the precision in the drilling. With rapid production and safe working, you can enjoy higher productivity.
Mobility and Transportation
How much space is available for mobility? If you have a small space, go with the compact designs that feature easy movement through the terrains. For the uneven terrains, crawler-mounted rigs are the best options.
Based on your needs, you can select mobility and transportation.
Safety Features
Look for the safety features. A noise and dust suppression system is the ideal choice in this case. It allows for the safety of your underground drills and avoids dust collection. As a result, you can enjoy better safety and easy management.
To eliminate the fatigue, you can opt for the ergonomic designs. They provide proper seating for the driver and workers to avoid excessive stress and provide a better working environment.
How do you choose the right drill according to the depth and rock formation of the mine?
Based on the depth and rock formation of the mine, you can go with the right drill type. For example, you consider the following options.
Shallow vs Deep mines
Which type of mining do you want to do? The type of underground drill changes from one type to another depending on the mining applications.
For example, you are going for shallow mining. They offer a drilling depth of 300m or less. The jumbo drills and percussion drills are ideal choices for such types of drilling options.
Suppose you have a drilling depth of 1000m or more. What do you think? Which drilling machine do you need? Either go for the diamond core drills or raise boring rigs.
Rock hardness and composition
Rock hardness can be a decisive factor. However, there are three fundamental rock categories. You can opt for the following options based on the hardness and composition.
- Soft rocks (e.g., limestone, coal) come with basic drilling options. For example, use rotary drills or percussion drills.
- For Medium to hard rocks (e.g., granite, basalt), you can opt for more compatible options. Long-hole or jumbo drills with high-power drilling capacity are the robust selection in this case.
- When you have Fractured or unstable rock, look for drills with adaptive drilling pressure. It will prevent borehole collapse and ensure a seamless experience.
