Study of Tunnel Damage Caused by Underground Mining

Bayueshan tunnel (BYS) is an important construction crossing over coal mine goaf. The underground mining subsidence has led the tunnel cracked seriously in three years after it was built. In order to evaluate the coal mine influence and future stability of the tunnels probability integral method (PIM) was used to calculate the tunnel deformation.

Strip Miningan overview ScienceDirect Topics

Andrew P. Schissler in Encyclopedia of Energy 2004 2.3 Strip Mining. Strip mining is employed in coal reserves where the overburden is removed in rectangular blocks in plan view called pits or strips. The pits are parallel and adjacent to each other. Strip mining is fundamentally different from contour or area mining on how the overburden is displaced called spoil handling.

How Are Diamonds Mined And Extracted From the Ground

The Mir open-pit mine ("World" or "Peace") in Russian city Mirny. Before any actual mining even takes place prospectors need to locate the diamond sources first. Geologists do this by following the trail of secondary diamond sources (e.g. river beds) to determine where the primary sources of pipe deposits are.
