        <p>Качество ископаемых углей, наряду с мощностью угольных пластов, яв­ляется ведущим признаком, определяющим промышленную ценность отдельных участков и шахтных полей угольных месторождений. Качество угля опреде­ляется при геологической разведке в каждом пересечении угольного пласта разведочной скважиной ...</p>

        <p>The quality of fossil coals, along with the thickness of coal seams, is the leading feature that determines the industrial value of individual sites and mine fields of coal deposits. Coal quality is determined during geologic exploration in each intersection of a coal seam by an exploration well ...</p>
