“…In the upper Silesia coal Basin (uScB), according to various estimates, between 700 million to 1000 million tons of hard coal waste has been accumulated [1]. depending on the mining and geological conditions prevailing locally in a given part of a coal seam, waste constitutes between 20% to 50% of the extracted mineral.…”

Assessment of the DetermineD GrounD CompACtion of AnthropoGeniC soilContAininG hArD CoAl mine WAste usinG the Dpsh DynAmiC probe the shortage of investment areas may be at least partially satisfied by the development of reclaimed post-mining areas. these are often subsidence zones levelled with hard coal mine waste or reclaimed sub-level old dumps of this waste. From the geotechnical point of view, such grounds represent anthropogenic grounds containing mine waste, and they are considered as possessing unfavourable properties in terms of the foundation of building structures. the paper initially presents the analysis of the properties of waste from the hard coal mining industry, emphasising that they expose several beneficial properties enabling their safe use. the second part of the article is devoted to the determination of soil density using the dPSH probe. It has been found that the applicable standards lack complex relationships that would allow for a reliable interpretation of the measurement results in a wide range of soil types. the last part presents exemplary results of measurements made with the dPSH probe at a construction site. The obtained results allowed for the formulation of several conclusions regarding the possibility of building on a ground made of hard coal waste and the use of dynamic sounding to assess the geotechnical properties of such anthropogenic soil.Keywords: anthropogenic soils/ground; dynamic probing; hard coal mine waste; made grounds; postmining land reclamation notation a 1 -coefficient dependent on the type of soil and the presence of groundwater a 2 -coefficient dependent on the type of the probe C u -coefficient of grain size uniformity e max -the maximum porosity index (at the loosest grain arrangement) e min -the minimum porosity index (at the densest grain arrangement)
