Coal gasification is a promising option for the future use of coal. Similarly to gasification in industrial reactors, underground coal gasification (UCG) produces syngas, which can be used for power generation or for the production of liquid hydrocarbon fuels and other valuable chemical products. As compared with conventional mining and …
Underground Coal Gasification (UCG) takes advantage of the same chemical reactions of coal to produce product gases, as those occurring in conventional gasifier reactors. The main difference is that in UCG the underground coal seam itself becomes the reactor, so that the gasification of the coal takes place underground instead of in a manufactured …
Coal is a black or brownish-black sedimentary rock that can be burned for fuel and used to generate electricity.It is composed mostly of carbon and hydrocarbons, which contain energy that can be released through combustion (burning). Coal is the largest source of energy for generating electricity in the world, and the most abundant fossil fuel …

This need was identified and addressed in a recent underground coal project completed by Coffey for Australian Coal Association Research Program (ACARP). The project …
1. Purpose of Mine Timbers When coal is removed from a seam, the rock strata immediately over the mined area becomes unstable due to the withdrawal of support and is eventually filled with cracks and openings. These openings vary in size, which depend on the nature of the strata. The fragments of rock nearest the…
In recent years, underground coal gasification (UCG) has received wide attention, which can convert in-situ coal resources into high calorific value synthetic gas, as a solution to the difficulty of mining operations in deep ground [9, 10]. Study on the hydrogen production from UCG is essential especially for countries with abundant coal ...
Robotic mining equipment plays an increasingly important role in the coal mining industry. Due to the complexity of the confined underground environment, available localization methods are limited, and restrict the development of coal mine robots (CMRs). Ultra-wideband (UWB) is a promising positioning sensor with high ranging accuracy. …
How to achieve reliable communication and safety monitoring is very important in coal mines. However, most of the existing transmission strategies and sensing-based monitoring approaches assume a single objective and neglect non-line-of-sight (NLOS) problems brought by winding tunnels or mine collapses. To this end, we first …
At the Pioneer Tunnel Coal Mine in Schuylkill County, visitors experience an authentic coal mining journey underground, traveling 1,800 feet into Mahanoy Mountain on a mine car. The Pioneer Tunnel coal mine tour uses open air mining cars to take you 1,800 feet inside of Mahanoy Mountain.
Removal of gas from the coal seam and surrounding strata has proven to be an effective method in reducing or eliminating outbursts. The benefits of gas drainage are: Gas given off from the coal is reduced so that gas percentage in intake airways and at working faces are kept within statutory limits and coal production rates are not ...
Zhucun coal mine is located north of the Jiaozuo coaleld in Henan Province, China, as shown in Fig. 1. The coal seam mined in the mine is coal seam 1 −5 of the Carboniferous Taiyuan Formation. Dec-ades of mining have been exhausting the No. 1−5 coal seam. Mining the remaining coal resources of the coal seam with complex geological ...
Cutting Processes. It has been stated that a longwall advances by cutting slices off the block. This is relatively simple for hand worked faces and with a coal plough, but with mechanized longwalls using shearers the means of doing this is not as straightforward as it would at first appear because of the complexity of the equipment.
Question: AZ Mining is a medium scale underground coal mining company. The company has been struggling to meet its production targets for the longest time. Management decided to conduct an audit to pinpoint the root cause of this problem and found that poor communication was the major contributor to this. The company has approached you to …
2003 Coal (and lignite) Production Statistics (source: EIA and MSHA) • 33% of all Coal Production in the U.S. is from Underground Mines • 63% of all Coal Produced East of the Mississippi is from Underground Mines – In all states east of the Mississippi, except Indiana and Tennessee, the majority of coal production comes from
Underground Coal TALPAC can be easily configured to accurately calculate the production from your longwall. For any given face configuration, Underground Coal TALPAC can be used to assess the differences between cutting systems. Quickly and easily assess the differences between bi-directional, uni-directional or hybrid systems …
Short-term geomorphic and hydrologic effects of subsidence induced by longwall mining under Burnout Creek, Utah were evaluated. During the year after longwall mining, 0.3–1.5 m of subsidence was measured near impacted reaches of the mountain stream channel. The major channel changes that occurred in a 700-m reach of Burnout Creek that was …

Underground coal gasification (UCG) is a promising option for the future use of un-worked coal. UCG permits coal to be gasified in situ within the coal seam, via a matrix of wells. The coal is ignited and air is injected underground to sustain a fire, which is essentially used to "mine" the coal and produce a combustible synthetic gas which ...
Ground control failures continue to be one of the leading causes of injuries and fatalities in underground coal mining.
