This book contains nine peer-reviewed articles on green coal mining that address most of the important issues associated with improving coal mining. These issues include the protection of water above coal mines, both surface and ground water, and the subsidence that occurs during and after mining with methods to limit it and methods of rehabilitation. Additional issues include mine entry and production area support and methods to control gas emissions.History of engineering & technologybicsscdecision makingmanagementminesmulti-criteria analysisprojectriskrestorationcoal ganguegeopolymermechanical activationthermal activationmechanical propertymicrostructurewater protectionwater-conservation coal mining (WCCM)influencing factors“five mapsthree zonesand two zoning plans”water conductive fractured zone (WCFZ)acoustic emission (AE)coaldeep miningmining layoutslignitereclamationrehabilitationland usedecision-makingoptimisationsustainabilitylongwall coal miningground controlsubsidenceupliftsurface movementradar-interferometrylong-term behaviorsustainable miningBelgiumfoamed concreteorthogonal experimentoptimum mixcoal mine goafgas isolationlongwall miningweak geological conditiongate-entry stabilityremaining coal thicknesswooden cribsgangueload-displacement characteristicspressure-compressibility characteristicsHistory of engineering & technologySpearing A.J.Sedt1291778Spearing A.J.SothBOOK9910557284003321Green Coal Mining Techniques 20203021911UNINA
