The frame with the data acquisition equipment is mobile and thus allows the measuring system to be installed in any point along the route of any belt conveyor. A base (reference) belt conveyor representative for the group of belt conveyors used in copper ore mines was selected for the tests.

Induced Seismicity: Mines located in seismically active regions, such as the Andean region — also known to be one of the wealthiest metallic mining zones in the world — are particularly at risk. Especially dangerous in underground mining areas, mine-induced seismicity also causes slope instability in surface mining.
