Portable Rock Drilling Machine Applications:
Mining: In mining operations, portable rock drilling machines are used for drilling blasting holes to break up the rock and extract minerals. They are also used for drilling ventilation holes, dewatering holes, and exploration holes.
Quarrying: Quarries use portable rock drilling machines to drill holes for blasting to break large blocks of stone into smaller, more manageable sizes. These machines are essential for the efficient and safe operation of quarries.
Construction: In construction projects, portable rock drilling machines are used for drilling holes for anchors, bolts, and dowels. They are also used for drilling foundation holes and for soil investigation.
DTH Rock Drilling Machine Advantages:
Portability: The main advantage of portable rock drilling machines is their portability. They can be easily transported to different job sites, reducing the time and cost associated with equipment setup and relocation.
Flexibility: DTH rock drilling machines can be used in a variety of environments, including narrow spaces, steep slopes, and remote areas. This flexibility allows them to adapt to different drilling requirements and site conditions.
Cost effectiveness: Compared to large scale drilling rigs, DTH rock drilling machines are generally more affordable to purchase and operate. They require less maintenance and have lower energy consumption, making them a cost - effective solution for many drilling projects.
Hand-held Rock Drills: These are the most portable type of rock drilling machines. They are lightweight and can be operated by a single person. Hand-held rock drills are commonly used for small-scale drilling tasks, such as drilling holes for anchors in construction sites or for sampling in geological exploration.
Jackhammer Drills: Jackhammer drills are larger and more powerful than hand-held rock drills. They are usually mounted on a frame or a tripod and can be used for drilling deeper and larger diameter holes. Jackhammer drills are widely used in mining and quarrying operations for blasting hole drilling.
Top-hammer Drills: Top-hammer drills are designed for medium to large-scale drilling projects. They use a top-mounted hammer mechanism to deliver high-frequency impacts to the drill bit. Top-hammer drills are known for their high drilling efficiency and are suitable for drilling in hard rock formations.
