Room & Pillar Mining Process
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.

Cat® Room & Pillar Mining Equipment
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.

Derby Underground Mine - Part 1 - Magazines Everywhere
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.

Underground coal mine by Indian minerology
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.[5] 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.

Glencoe North Tunnel Quarry Underground Exploration: Rooms and Pillars! Big ones!
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!!

Room And Pillar Method In A Red Ore Mine
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.
