Bench And Long-Hole Drilling T45 (1 3/4 “)

Date: May. 08, 2024

Bench and long-hole drilling using T45 drill rods with a diameter of 1 3/4″ (44.45 mm) are common practices in mining, quarrying, and other industries where rock excavation is necessary. Here are some key points about T45 drill rods and their use in these applications:

1. Material Grade: T45 refers to a specific material grade or specification of the drill rod. This grade typically represents a medium-strength alloy steel that has been designed for use in rock drilling applications.

2. Diameter: The 1 3/4″ (44.45 mm) diameter is a common size for drill rods in various drilling applications. This size allows for good penetration and hole formation while also providing adequate strength and durability.

3. Bench Drilling: Bench drilling typically refers to drilling shorter holes from a raised or “bench” position, such as along the edge of a pit or quarry. These holes are often used for blasting or for placing explosives to facilitate rock fragmentation.

4. Long-Hole Drilling: Long-hole drilling involves drilling deeper holes, often exceeding the height of the bench. These holes are used for blasting large areas of rock to create larger excavation volumes.

5. Applications: T45 drill rods with a 1 3/4″ diameter are commonly used in both bench and long-hole drilling applications. They can be used with various types of drills, including pneumatic, hydraulic, and electric drills, depending on the specific needs of the operation.

6. Features: T45 drill rods are designed to withstand the high forces and vibrations encountered during drilling operations. They often have threaded ends to allow them to be connected to other rods or to the drill bit. The rods may also have other features, such as a tapered design or special coatings, to improve drilling performance.

7. Safety Considerations: When using T45 drill rods for bench and long-hole drilling, it is important to follow safety protocols and procedures. This includes wearing appropriate protective equipment, ensuring the drill is properly maintained, and adhering to industry standards and regulations.
