6 FAQs about [Mine rock drill diagram]

What is a drill in surface mine?

1. DRILLING IN SURFACE MINE Manas Kumar Mallick Assistant Professor Department of Mining Engineering BIT Sindri, Dhanbad MODULE -3 2. Introduction • Drilling equipment and methods are used by the construction and mining industries to drill holes in both rock and earth.

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 are the principles of rock drilling?

5. 1. The principle methods of rock drilling used in mines today are mechanical and driven by either impact or simple rotation. 2. Alternative methods, employing heat, flame, high- pressure water, or high voltage electric discharges, for example, are used only in particular situations or in laboratory studies. PRINCIPLES OF DRILLING 6.

How rotary drilling rigs are used in open pit mining?

For large-scale open pit mining, it is common to use rotary drilling rigs equipped with three-cone bits or DTHs to drill blastholes. These tools are mechanically compatible with each other, and make it possible to choose the most efficient method according to the particular rock hardness. 2. Construction of Drilling Equipment

What type of rock can be drilled with a rotary drill?

• Rotary drilling is limited to rock with low tensile strength such as salt, silt and soft limestone not containing abrasive quartz minerals. • Maximum single-pass drilling: 20 m (65 ft.). • Percussion drilling is suitable for unconsolidated and consolidated formations: Sand, silt, stiff clays, sandstone, laterite and gravel layers.

What is the main purpose of drilling in mines?

The predominant purpose of drilling in mines is to construct blastholes for tunneling or mining, although subsidiary drilling is used to insert rock bolts or cable bolts, or to facilitate exploration or mine drainage.
