Once a mining lease has been awarded to an operator, exploration ( evaluation of the resource) takes place, followed by a planning and development process before excavation or mining begins. The initial task is to gain access to the seam from the surface by some means (shafts, drifts, etc see Access to Seam from surface section for these terms).
9 mine diagrams Any self respecting geek who has been spellbound by the inspired rescue of the Chilean miners, will have found plenty of great infographics showing just how impressive a mine is. Here we have gathered some other cutaways, sections and 3d models showing a variety of mines, from the two coal mine alternatives (room and pillar or longwall) to the cavernous chambers of salt mines.
process flow diagram for coal mining ppt. Basics of openpit mining. Mar 13, 2012#183; What is Opencast Mining Opencast mining is also known as Open pit mining, Open cut Mining, Surface or Strip Mining The coal upto economical depth will be excavated by OC Method The current operating depth of OC mines in SCCL is about 200m and SCCL proposed to operate OC mines upto a depth of 420m.
The history of coal mining goes back thousands of years, with early mines documented in ancient China, the Roman Empire and other early historical economies. It became important in the Industrial Revolution of the 19th and 20th centuries, when it was primarily used to power steam engines, heat buildings and generate electricity. Coal mining continues as an important economic activity today

This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Copper Mining and Copper Extraction Process Starting from either openpit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral ore Having a quick look now at how porphyry ores are treated and
Mining the Coal. Coal miners use giant machines to remove coal from the ground. They use two methods: surface or underground mining. Many coal beds are very near the grounds surface, and about twothirds of coal production comes from surface mines. Modern mining methods allow us to easily reach most of our coal reserves.
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is a ''pit'', and
#0183;#32;Underground mining, sometimes called deep mining, is a process that retrieves coal from deep below the Earths surfacesometimes as far as 300 meters (1,000 feet). Miners travel by elevator down a mine shaft to reach the depths of the mine, and operate heavy machinery that extracts the coal and moves it above ground.
The Mining Process. 1. Mining open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.
2 #0183;#32;Although the United States has the vast coal resource described in the previous chapter, perhaps as much as 4 trillion tons, the key issue for policy makers is the amount of coal that is economically is not a fixed quantity, but depends on the geological resource, the market price, and the cost of mining. The particular characteristics of the coal mining
The Longwall Mining Process Fig., below, shows a cutaway diagram of a typical longwall mine. The main features of the mine are In longwall mining, a panel of coal, typically around 150 to 300 metres wide, 1000 to 3500 metres long and 2 to 5 metres thick, is
