6 FAQs about [Structural drawing of hydraulic rock drill for mining]

How does good drilling work?

Good drilling means that the entire system, from rock drill to drill steel to the rock itself, must harmonise. Here’s how it works. Percussive drilling breaks the rock by hammering impacts transferred from the rock drill to the drill bit at the bottom of the hole.

What types of drilling methods are used in mines today?

The principal drilling methods used in mines today are mechanical ones in which a drill drives cutting tools into rock by means of static or dynamic force.

What type of drill is used in mining?

Percussion rock drills are the most commonly used equipment for drilling in small-scale surface or underground mining situations, whereas rotary crushing drills or down the hole drills (DTHs) are generally employed for mining in large-scale surface mines.

What type of drill do hard rock miners use?

In general, hard rock miners use top hammer drills for holes less than 4 inches (150mm) in diameter, and ITH drills for larger holes. Miners still use blade bits (chisel or cross) for drilling small diameter blastholes in hard rock; button bits are normally more economical in the larger diameters.

What are the components of a drilling system?

The essential components of a drilling system are the rock drill, feed equipment, drilling rods, bit, supports against the drilling reaction, power source, and cuttings disposal equipment. Different drilling rigs are constructed with various combinations of these elements and other accessories for particular drilling purposes.

What is a structural analysis of a drill core?

The aim of any structural analysis of drill core should be to constrain the 3-D geometry and properties of ductile and/ or brittle structures and to develop an understanding of the deformation history in terms of timing and kinematics.
