Long wall mining is a mostly automated process whereby long wall mining machines are used to extract blocks of deposits as wide as the face of the equipment and potentially kilometers long Cutters are then used to cut the deposits from the face of the equipment Room and pillar mining is a common underground mining method for mining oil shale
Thus in 1862 the oil shale mining industry began Large refineries were built where the shale was heated in retorts to release the hydro carbon content Most of the Scottish oil shale mines closed between the wars but a few survived until around 1962 when they too closed in the face of cheaper imported oil from Arabia The industry s
·The combination of multi stage hydraulic fracturing with horizontal drilling has untapped the potential of shale reservoirs Hughes 2013; Middleton et al 2017 Currently shale reservoirs account for 70% of the US natural gas production and 60% of the US oil production as shown in Fig 1 Total primary energy supp 1990 However the majority of the pores in these
·The Future of Mining This brings us to an important final point cryptocurrency does need a future beyond mining Not only is it costly to mine new coins thanks to the price of electricity and GPUs it s also bad for the environment as this article from the Columbia Climate School What that future will be is hard to say exactly maybe it s staking maybe it s
·The cause of shale instability is two fold mechanical stress change vs shale strength environment and chemical shale/fluid interaction—capillary pressure osmotic pressure pressure diffusion borehole fluid invasion into shale International Journal of Rock Mechanics and Mining Science & Geomechanics Abstracts 25 3 171 182
·Oil shale is a kind of unconventional energy resource with abundant reserves but its exploitation has a continuous negative impact on the environment which has hindered the research and exploitation of oil shale under the international environmental consensus on issues such as climate change Therefore more attention should be paid to environmental problems
