The mechanical parameters of mining waste from Lublin coal carreerconsidered as material for leveles hydrotechnical structures

The article presents the properties of mining wastes from the Bogdanka Mine in Lubelski Coal Basin. Most important geotechnical parameters, which should be known in designing engineering embankments are discussed in details. These parameters are: grain size distribution and shear strength of soil. The water content, optimum moisture content, maximum dry density of solid particles are also presented. These parameters will be characterised in relation to the different storage time. ...
