ADVANCING AND RETREATING LONGWALLS:- Advancing Longwalls:- In this method, the face start point is close to the main headings, usually leaving a barrier pillar to protect them. Once the face equipment is installed, extraction commences working away from the main headings towards the block limit. Obviously the main and tailgates do not exist prior to the start of extraction and have to be formed at each end of the face as mining progresses. The gate roads are effectively in the goaf and a false rib has to be installed on one side, usually by constructing a small pillar, sometimes using stone cut from the roof in thin seams or using some type of cementitious material brought into the mine. Such gate roads tend to require a very heavy support system (yielding steel arches have often been used). Principle of advancing longwall Advancing longwalls were once common in Europe in relatively thin seams where packs were constructed using stone, which had ...
Which is the deepest mine in India? Which is the deepest mine in India? Mining is all about who well you can dig and how deep you can dig to get the desired mineral. In the process, India have also evolved to innovate methods to dig deep and have constructed one of the world's deepest mines.
Continuous Miner:- Continuous Miner:- A continuous miner is a mining machine that produces a constant flow of ore from the working face of the mine. The machine continuously extracts as it is loading coal with a cutting steel drum and conveyor system. Continuous miners are typically used in room and pillar mining operations. The continuous miner is different from conventional or cyclical mining methods, which halt the extraction process in order for ore-loading to proceed. Continuous miners, which began to take off in the mining industry in the 1940s, make up of 45 percent of the underground coalmine production. Today, continuous miners are being developed as driverless machines controlled via remote control. History:- Early Miners:- The continuous miner has been available in some form since the late 1800s. The first machine to resemble a continuous miner was known as the English Channel Machine. The pneumatically driven machine could travel 1.5 miles (2...
