Caterpillar has extensive experience in the design of roof supports for specific mining conditions. Cat Longwall Top Coal Caving (LTCC) roof supports allow mining of seams seams thicker than 6 meters (20 feet). Following a conventional cut with a shearer to about 3 m (9.8 ft) the roof supports move forward and allow the caving of the top coal behind the roof supports a second conveyor mounted gob-side. This special LTCC method enables increased coal reserve recovery for only an incremental additional cost. This animation shows how it works.

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.

Ancient mining techniques go well back into our history – well back into ourprehistory, in fact. As we progressed through the Stone Age, with more and more sophisticated tools and weapons being designed and developed, so too,our need for more and better raw materials for these implements. Stone and flint led to copper, then bronze, gold, silver, iron… all in the name of progress, war, technology, vanity or greed. In fact, it’s ironic (pun intended) that the substance prized and even mined by our ancient ancestors for some of the earliest stone tools and weapons – flint – was later a hindrance encountered by Classical miners – who were in many cases also Classical minors – in gold mining galleries described by Pliny the Elder in the 1st century AD as “thought to be the hardest thing that exists, except greed for gold, which is the most stubborn of all things.

- Like our Facebook: https://www.facebook.com/oilvips - Oil and gas are generated from a source rock, organic matter buried in the depths of the earth. Once formed, they climb back towards the surface. On their way, cap rocks can impede their progress and they accumulate in reservoir rocks. Here they constitute hydrocarbon fields, which can be identified by interpreting seismic data (a sort of echography). The data is obtained with the help of a seismic ship. To confirm the interpretations of seismic data, two types of drilling gear exist. Each is adapted to a range of depth of water (down to more than 2500 meters). The platform seen here is a semi-submersible, which floats and retains its stabilised position by means of anchors fixed on the seabed. Platforms at sea are used not only for drilling but also for the production of hydrocarbons. This production consists of the separation of oil, gas and water, before the oil and gas is taken by pipeline towards a mainland terminal. Where it is impossible or too expensive to link the field to the coast by a pipeline, an FPSO ship is used (Floating Production Storage and Offloading barge). Onboard, the hydrocarbons and the water are separated. The oil is stored prior to being loaded on tankers and the gas is re-injected into the reservoir rocks. Gas from a field is taken to land through an underground gasoduct to a processing plant. There, if the gas is to be transported by sea, it is converted into liquid obtained by cooling it down to --163°C. When it arrives at the plant terminal, the liquid natural gas (LNG) is returned to its gaseous state in a re-gasification plant, before being introduced into the local gasoduct network. The LNG is stored in tanks before re-gasification. The crude oil is transported in a petroleum tanker, the capacity of which can attain 200 000 tons. It is commonly called a "super- tanker". The terminals capable of receiving such giants are few and far between. The ships used to transport the crude oil produced on an FPSO ship are of a much smaller capacity. The crude oil, before being refined, is stored in the port in the large capacity tanks. The natural gas is preserved in reservoirs (artificial or natural). It is ready to be injected by pumping into the gasoduct network for industrial and domestic use or as fuel in power-generating stations. As far as the crude oil goes, it is transported by oleoduct to the refinery. There it undergoes a number of transformations and blending. A variety of finished products are obtained (LPG, petrol, kerosene, diesel ...), or naphtha, which will be used as the basis for the composition of plastic products by complex petroleum chemistry. --------------------------------------------------------------------------------------- Like our Facebook: https://www.facebook.com/oilvips Twitter: https://twitter.com/oilvips And Don't forget to subscribe to our channel
