The machine is generally operated from a bench that is created by the removal of overburden material and coal by way of contour surface mining around the perimeter of a coal seam. Other highwall appliions include previously augered areas and trench mining.
generally causing some surface subsidence. Extraction by longwall mining is an almost continuous operation involving the use of selfadvancing hydraulic roof supports, a sophistied coalshearing machine, and an armored conveyor paralleling the coal face. Working under the movable roof supports, the shearing machine rides on the conveyor as it

The term "continuous" as applied to development machines has been one of the biggest misnomers used for mining equipment because, on development, they are usually anything but continuously cutting. The main delays mostly occur while roof support is installed and often waiting for shuttle cars to return from their discharge point for reloading.

Aug 20, 2010 · Mining equipment is huge, dauntingly so at times. And while their bulky exteriors protect the operator from the rugged terrain and falling objects, they also cause blind spots and limited maneuverability—major contributing factors to mine vehicle related collisions and other accidents. Also, operator attention and fatigue must be considered, too.

The bucket wheels in the ore load the material to conveyors for transporting out of the pit. Continuous surface mining has been a dream of mining engineers. Several equipment manufacturers have developed continuous surface miners which employ a milling cutter head to cut and load the rock on to trucks or conveyors.
Traditional surface mining has left untold tons of minerals underground, simply because there was no way to get to it safely and efficiently. The Vermeer innovative Terrain Leveler ® surface excavation machines can work where explosives can''t, with topdown cutting that lets you reach valuable mineral seams and get the most product out of the ground as possible.
