Coal Mining Methods - EMFIEnvironmental Risks of Mining

Extraction by longwall mining is an almost continuous operation involving the use of self-advancing hydraulic roof supports, a sophisticated coal-shearing machine, and an armored conveyor paralleling the coal face Working under the movable roof supports, the shearing machine rides on the conveyor as it cuts and spills coal onto the conveyor forMost underground mining operations increase sedimentation in nearby rivers through their use of hydraulic pumps and suction dredges; blasting with hydraulic pumps removes ecologically valuable topsoil containing seed banks, making it difficult for vegetation to recover (Miranda et al, ).
