Mining exists in many countries. London is known as the capital of global "mining houses" such as Rio Tinto Group, BHP Billiton, and Anglo American PLC. The US mining industry is also large, but it is dominated by the coal and other nonmetal minerals (e.g., rock and sand), and various regulations have worked to reduce the significance of mining in the United States. In 2007 the total market capitalizationof mining companies was reported at US$962 billion, which compares to a total global market cap of publi…
Blasting equipment is used for both underground and open pit mining operations and is known to be one of the most hazardous aspects of the job. For mining operations to be successful good blast designs are absolutely vital as poor practices and excessive explosives can result in damage to rock structures causing unwanted caving.
Each segment requires the use of specific equipment, but there are several types of mining equipment that are used throughout the industry. This equipment includes excavators, draglines, drills, roof bolters, continuous miners, longwall miners, rock dusters, shuttle cars and scoops. Excavators. Miners traditionally used shovels and steam shovels to break and remove earth, but today’s miners ...
Coal India’s consultancy arm, Central Mine Planning & Design Institute (CMPDIL) has also tied up with Centre of Aerospace Research (CASR), Anna University of Chennai for acquiring expertise in drone technology. It has ordered two drones which once delivered with necessary retrofit equipment will provide the company with the necessary expertise to deploy them at mines.
This project conducted research needed to make recommendations and guide policy or program decisions regarding the safety of batteries used in underground coal mines. The research objectives for this project were addressed by way of the following project tasks:

Venturis, or air movers as they are known, typically concentrate airflows in underground mines by enabling high-velocity air to be directed at a point to prevent methane layering at roof sections of underground coal mines. One miner said “when used effectively, they can improve ventilation in hard to reach mine headings and ensure that short ...

Coal mining - Coal mining - Choosing a mining method: The various methods of mining a coal seam can be classified under two headings, surface mining and underground mining. Surface and underground coal mining are broad activities that incorporate numerous variations in equipment and methods, and the choice of which method to use in extracting a coal seam depends on many technological, economic ...
Longwall Miner. Twenty percent to 30 percent of mined coal underground is from longwall mining. This is performed by a mechanical cutter that shears coal off from a panel on the seam.

In surface mining, the ground covering the coal seam (the overburden) is first removed to expose the coal seam for extraction. The elements of a surface mining operation are (1) topsoil removal and storage for later use, (2) drilling and blasting the strata overlying the coal seam, (3) loading and transporting this fragmented overburden material (called spoil), (4) drilling and blasting the ...
Coal mining has been performed since the arrival of the Industrial Revolution in the mid-18th century. Coal is used as a fuel primarily for steam-generated electrical power plants, as well as being a component of certain industrial applications, such as steel manufacturing.
