Drift mine An underground coal mine in which the entry or access is above water level and generally on the slope of a hill, driven horizontally into a coal seam. Drill A machine utilizing rotation, percussion (hammering), or a combination of both to make holes. If the hole is much over in diameter, the machine is called a borer.
Introduction. Mine dust is one of the main threats to coal mine safety in China. In the process of coal production, operations such as drilling, blasting, tunneling, mining, coal falling, transportation, transfer and support, shifting frame etc. will produce large amount of dust (Wang et al., 2019, Geng et al., 2014).
Coal mining Underground, Surface, Drilling: 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, and ...
A coal mining method that accounts f or less than 1% of deep coal production, Shortwall involves the use of a continuous mining machine with mov eable roof supports, similar to longwall .
Among underground coal miners, hearing loss remains one of the most common occupational illnesses. In response, the National Institute for Occupational Safety and Health (NIOSH) conducts research to reduce the noise emission of various underground coalmining equipment, an example of which is a roof bolting machine.
Introduction. Explosives are probably the most costeffective method of rock excavation in underground mining operations 1 and underground rock excavation have largely relied on drilling and blasting methods in recent years and type of explosives, drilling patterns, and the sequence of initiation are all critical to the successful excavation of rock masses 5.
Types of Mining and Their Respective Equipment. Mining can happen at the surface or underground. The environment and type of material mined dictate the form of mining required and the equipment used. Both surface and underground mining have three main steps: Extraction: This involves drilling, blasting, or digging to remove materials from the ...

Longwall mining machines are the most common machines used in underground coal mining. These mining tools are used to build underground galleries and tunnels by leveraging ...
Gas explosions threaten the safety of underground coal mining. Mining companies use drilling rigs to extract the gas to reduce its concentration. Drainage depth is a key indicator of gas drainage; accidents will be caused by going too deep. Since each drill pipe has the same length, the actual extraction depth is equivalent to the number of drill pipes multiplied by the length of a single ...
Coalbed methane (CBM) drilling and completion technologies (DCTs) are significant basis for achieving efficient CBM exploration and exploitation. Characteristics of CBM reservoirs vary in different regions around the world, thereby, it is crucial to develop, select and apply the optimum DCTs for each different CBM reservoir. This paper firstly reviews the development history of CBM DCTs ...

M. Albert Evans Raja Venkat Ramani. Coal mining, extraction of coal deposits from the surface of Earth from underground. Coal has been used since the Bronze Age, 3,000 to 4,000 years ago, and was the basic energy source that fueled the Industrial Revolution of the 18th and 19th centuries.
Coring ( diamond drilling) is another way of collecting information about a potential coal resource. The drill rig is equipped with a hollow tube, and as the drill pushes the rods into the ground, a cylindrical piece of the rock is pushed into the hollow tube. These samples are usually the length of a drill rod, which is 6 meters.
Coal is probably the most common example. Much of the mine development tunnelling in underground coal mines is done in coal. If that is not practical, for example where tunnels must be driven in the over or underlying rock, the same type of machine can sometimes be used, especially where the ... Shaft drilling machines use fluid to flush the ...
Underground mining. Underground or "deep" mining consist mostly of two methods roomandpillar and longwall mining. In roomandpillar, coal deposits are mined by cutting a network of "rooms" into the coal seam and leaving behind "pillars" of coal to support the roof of the mine. The coal is extracted in two phases, first with the ...
