    In contrast, underground mining requires the creation of two parallel and vertically connected tunnels where miners in the top tunnel blast the ore of the kimberlite pipes which falls and collects on the bottom tunnel Marine diamond mining The third method, marine diamond mining, extracts diamonds from the ocean floor While the earliest formA method of shorthole mining, cutandfill mining is used in irregular or steeply dipping ore zones, especially where the hanging wall limits the use of longheld methods The ore is mined either in slightly inclined or horizontal slices then it10 Different Types of Mining Operations and Mines Nayturrsubsurface may not be prohibitive Reflection seismic methods provide fine structural detail and refraction methods provide precise estimates of depth to lithologies of differing acoustic impedance The refraction method has been used in mineral investigations to map lowvelocity alluvial deposits such as those that may contain gold, tin, or sandGEOPHYSICAL METHODS IN EXPLORATION AND
