· Highwall mining differs from continuous mining in that it is carried out by remote control at the surface. Here, an operator, usually loed in a cabin, uses a television monitor to control the progress of the continuous miner machine. Highwall mining is often used when excavating an openpit mine becomes too expensive.

INTRODUCTION : Continuous mineris a machine used for cutting and loading of coal used in underground Board and Pillar mining operation. The JOY continuous minerproduct line has been developed to meet the high productivity requirements of today's underground mining .
Continuous miners cut and gather the material simultaneously and convey it into shuttle cars, haul trucks or a continuous haulage system. They are typically used for fullscale production in roomandpillar mining operations. The flameproof design of these machines is certified according to national regulations, such as MSHA (USA), SANS (South ...

Continuous operations Miners have always looked for more continuous mining systems where possible. IM looks at recent developments in open pits, with everlarger inpit crushing, higher capacity conveying and bigger machines 00 International Mining NOVEMBER 2006 SURFACE MINING D evelopments in continuous surface mining are all helping satisfy the
BACKGROUND OF THE INVENTION. The invention concerns continuousoperation extraction machinery for strip mining that travels under its own power on continuous track treads and includes a cylindrical extractor with blades distributed around it, whereby the extracted material is transferred through a chute to a conveyor belt positioned axially inside the cylinder.
Sandvik borer miners perform fullface cutting with two large radial cutters. They are designed to cut and deliver material to auxiliary haulage equipment in a continuous operation. Sandvik borer miners can keep up with haulage equipment removing excavated material and offer an effective and highly productive solution for driving entries, mining rooms and extracting pillars.
