POWERED SUPPORTS – Mining Science and Technology

As the shearer traverses along the coal face the supports are advanced to enable the shearer to cut a fresh web of coal when it returns. There are two methods of advancing powered supports, these are: Conventional Method of Advancement. In the conventional method the supports are stood up to the conveyor before the shearer cuts a web of coal. After the shearer passes the
