Mali rock drill structure diagram
Drilling derricks and Rig Masts consist of a steel framework with a square or rectangular cross-section. Their purpose is to support the hoisting equipment and rack the tubulars while tripping pipe. The number of joints in a stand (single-double-triple) that the rig can. . The Crown Blockas a drilling rig component is a fixed set of pulleys (called sheaves) located at the top of the derrick or mast, where the drilling line is threaded. The companion blocks to these pulleys are the traveling blocks. By using two sets of blocks in this fashion,. . Attached to the bottom of the traveling blocks, the hook is required to hang the swivel and rig kelly(for drilling) and the elevator bales (for tripping pipe and casing). . The Drawworks is one of the most important components of the drilling rig (types of drilling rigs). The unit supplies the hoisting power, the. . The Traveling Blockis a set of sheaves (pulleys) that move up and down in the derrick. The drilling line is threaded (reeved) over the. [pdf]FAQS about Mali rock drill structure diagram
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 drilling machine PDF?

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 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.
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 drilling rig is used in open pit mining?
In practice, small-diameter drilling is required in underground mining and tunneling, medium-diameter drilling in quarries, and large-diameter drilling in large-scale 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.
