Room and Pillar Mining: Modern Coal Mining at Its Best When it comes to underground mining, there are different ways to approach removing coal, depending its structure and location. At the current Carlisle Mine and developing Bulldog Mine, Sunrise Coal is using the room and pillar method. Safe, Efficient & Environmentally Friendly Room and pillar is a non-subsidence plan for a mine, preserving the precious farmland above. It is among the safest and one of the most ecologically-friendly approaches to mining coal today, creating a non-subsidence environment (no movement of land) and maintaining clean water standards. Removing Coal from the Earth As the name indicates, large pillars of coal (40 feet wide) are left standing to help support the roof of the mine—more than half of the coal remains intact as supporting pillars to maintain the integrity of the surface land. The end result is a grid of open space (rooms) cleared by a continuous miner machine and separated by pillars. Once the coal is cleared and placed on a conveyor belt to our state-of-the art surface wash plant, roof bolters enter the new area to secure the roof, inserting fully grouted 6-foot metal rods every four feet. At the wash plant, rock and debris are separated from the coal so that it can be cleansed of sulfur and other minerals in preparation for our customers.

Various machinery combinations are used for extracting. One of the combination is the continuous miner and shuttle car. Continuous miner cuts the coal from seam and load into shuttle car. This video shows working the combination of the Continuous miner, feeder breaker, power central, load haul and dump machine , shuttle car and roof bolter effectively. It has a working sequence according to an availability of the face. All these explanations are in the Hindi language.

The room & pillar mining method is used predominantly for underground coal deposits, however also for potash deposits. Coal is not completely being mined out from the underground deposit, but pillars are left standing to keep the roof from caving in. Caterpillar offers a complete range of machinery for this mining method. The extensive room & pillar product line includes a seamless range of continuous miners, face haulers, continuous haulage systems, feeder breakers, roof bolters as well as a broad range of battery- and diesel-driven utility vehicles like scoops and LHD vehicles.

The Australian Centre for Geomechanics has developed this safety training DVD for underground metalliferous mine workers. To purchase this product or find out more information, visit http://www.acg.uwa.edu.au/shop#trainprods Overview All underground mine workers will be exposed to drilling and blasting processes. The aim of this new DVD is to provide workers with the critical knowledge on drilling and blasting to aid appreciation of the importance of these mining processes and their related hazards. The DVD features an introduction to the rock breaking process in mining, followed by a section on how to handle, store and transport explosive products. The third part of the DVD covers development drilling and blasting practices; and the fourth part discusses production drilling and blasting. Target Audience Underground mine workers - the need to identify the potential hazards of working near or with explosives, and the protocols of re-entering a working area after blasting. Workers responsible for development and production drilling and blasting activities. This DVD will review drilling and blasting fundamental concepts that are critical to achieving optimal rock breaking outcomes. All industry stakeholders - those keen to learn more about drilling and blasting in underground mines. Project Sponsors: Barrick Gold of Australia; BHP Billiton Olympic Dam; Dyno Nobel Asia Pacific; Gold Fields Australasia; Newmont Asia Pacific; Orica Mining Services; Xstrata Zinc.

It's been a while! My work schedule has finally lightened up enough to give me some time to explore. To kick things off, we took a drive out to Perry County, deep in the Hoosier National Forest of Southern Indiana. This mine is located on the USFS' Rainbow Lake Recreational Area. Today, we're documenting the Derby Underground Mine, an underground (surprise) limestone mine operated by Mulzer Crushed Stone and shut down in November of 1982. This was a room-and-pillar mine, bypassing about forty feet of shale overburden by putting a pair of drifts into the side of a surface trench. It's very likely that converting to underground mining actually reduced unit mining costs here, as it completely eliminated any requirement to strip overburden. Sometime after 1982, Conex Controlled Explosives used the property as a depot for storage of explosives to be used at surface mines in the region. Intriguingly, both MSHA and the USGS MRDS database mention the Derby Slope Mine alongside the Derby Underground Mine. The Derby Slope closed in 1985, and does not appear on USGS topographic maps of the area (though, curiously, the Derby Underground does not either). I am virtually certain that the decline entry for the Derby Slope is located across Highway 70 from the mine we visited today, and that it is completely flooded. Sadly, slopes have a tendency to flood. What little information I can find on this mine indicates that it was worked intermittently as weather permitted; I have not found any references to when underground mining began at this location. Were this mine worked continuously, I would estimate it to have taken one to two years of mining to reach its current footprint - but it was not worked continuously, so it's really anyone's guess.

Joy Mining Machinery releases a new version of its most popular video "Pioneering Underground Mining". You can request a free copy of this video by contacting [email protected] and provide your name and mailing address and if you want the copy in DVD or Blu-ray format. It was first produced in 2001 to support a request by our US Midwest sales region to help a customer explain the difference between room and pillar and longwall mining to finance people. It quickly became the most widely distributed video in our library being used by universities, schools, shown to community groups, etc. The program was updated to show new products and includes all new HD video and animations.

Underground coal mine :- Most coal seams are too deep underground for opencast mining and require underground mining, a method that currently accounts for about 60 percent of world coal production. In deep mining, the room and pillar or bord and pillar method progresses along the seam, while pillars and timber are left standing to support the mine roof. Once room and pillar mines have been developed to a stopping point (limited by geology, ventilation, or economics), a supplementary version of room and pillar mining, termed second mining or retreat mining, is commonly started. Miners remove the coal in the pillars, thereby recovering as much coal from the coal seam as possible. A work area involved in pillar extraction is called a pillar section. Modern pillar sections use remote-controlled equipment, including large hydraulic mobile roof-supports, which can prevent cave-ins until the miners and their equipment have left a work area. The mobile roof supports are similar to a large dining-room table, but with hydraulic jacks for legs. After the large pillars of coal have been mined away, the mobile roof support's legs shorten and it is withdrawn to a safe area. The mine roof typically collapses once the mobile roof supports leave an area.

This video is the result of three visits to this site. The Glencoe South Tunnel Quarry is on private land and does not appear accessible; it took some time to confirm this. Something, either mining or construction, is going on underground at that mine as well- we could hear heavy equipment running underground on a previous visit. As best I can tell, the Glencoe North mine was worked into the late 1950s for limestone. It is a fairly small mine, smaller than the Osage Asphalt operation that made up our last foray into underground limestone. Subsidence is occurring at several points in this mine, and daylight can be seen. I believe that those portions are in somebody's backyard!!

Exploring deep inside a beautifully intact 1890's era red ore mine. Mining methods back then called for the room & pillar method when extracting red ore while going deep underground. Large sections were left intact for better roof support. Coal mines also adapted and used this mining method. The flooded sections of this mine were encountered roughly 1300 feet down from the opening. Very rare access was granted to explore this site as it resides on private property.
