IMO, UG placer mining cannot compete with bulk, lowgrade surface mining or hardrock, highgrade UG mining but it's an interesting idea! Roadheaders have gotten stronger, but still not passing 150 MPa. A solution mine was proposed in AK, basically highpressure injection wells and pumps to mine "pods" of an extensive horizontal pay layer on bedrock.
mine in order to support the overlying strata. The minedout area is allowed to collapse, generally causing some surface subsidence. Extraction by longwall mining is an almost continuous operation involving the use of selfadvancing hydraulic roof supports, a sophisticated coalshearing machine, and an armored conveyor paralleling the coal face.
Mining3 developed the Oscillating Disc Cutter, which was licensed in 2006 by Joy Global (now Mining Corp) and rebranded as DynaCut™. With relatively low input power, the DynaCut cutting technology – now incorporated into 's DynaMiner machine – enables continuous, or semicontinuous mining of hard rock in both surface and underground applications.

Surface mining. Strip mining is sensible when the ore body is near the surface. The practice includes some of the largest machines on earth, removing long strips of overlying soil and rock and then removing coal deposits. Openpit mining utilizes blasting and mineral removing, digger deeper into the earth causing a craterlike result.
