Oct 17, 2019nbsp018332There is a variety of mining methods used, often in the same mine, depending on the geometry of the orebody and the stability of the rock. Ore is broken up by blasting and drilling. Ore is then removed or mucked out by a LHD load haul dump machine, which resembles a low-profile articulated front-end loader.

Satellite imagery is vital for early exploration and is typically one of the first data types acquired by anyone working in a new area. When combined with field mapping and geophysics it becomes a very efficient way to gain geological understanding. Today we can obtain imagery from a wide variety of satellite systems like Landsat, WorldView, SPOT, RapidEye and EROS, amongst others.
