Determining Mechanical Properties and Material Models of Subsoil for Buildings in Mining Areas (original) (raw)

Preventing mining damage buildings can sustain, entails above all determining correctly interactions in the soil (and consequently the load-bearing structure) caused by exploitation. Processes involved in deposit mining cause damage to a rock mass’s structure around the excavation and cause deformation of surface layers. Under Polish conditions, underground mines are located almost exclusively in areas, where exploration has taken place for many years. Mining history of the Upper Silesian Coal Basin region dates back as far as 160 years. It comes as no surprise, than that rock mass’s structure in those areas has been signio cantly affected. Repeatable mining in? uences leave their mark on mechanical properties of soil. Therefore it is important, not only to factor in at the stage of designing a building the direct impact of planned excavation, but also properties of soil have to correctly evaluated. Investigation of geologic and geotechnical conditions of foundations should draw bas...
