Reclamation problems for the area of a former borehole sulphur mine with particular reference to soil air properties

Bryk, M. | Kołodziej, B.
In order to select appropriate methods of reclamation of anthropogenic soil in the area of the former 'Jeziórko' borehole mine, the air capacity and air permeability of the soil were measured. A field covering an area of 6·25 ha in which the former mining boreholes were only eliminated and no other reclamation treatments carried out was chosen for the study. The control stand was located in phytocoenosis Querco-Fagetea situated in the vicinity of the sulphur mine, but outside the area of direct mining activities on Haplic Gleysol. Samples were collected from 0-10, 10-20 and 20-30 cm layers in 25 equally distributed locations of anthropogenic soil and 1 of natural soil. The soil water-air properties at the soil water potential of -9·81 kPa and at the potential at the time of soil collection (the so-called actual state) were determined. Spatial relations in the capacity and air permeability observation series were assessed for post-industrial soil by geostatistical methods. Kriging with a linear variogram was used. Geostatistical analysis made mapping of the air properties of heterogenic soil cover in the study area possible. Non-reclaimed soils of the experimental field were characterized by faulty aeration resulting from a relatively low air capacity and, additionally, insufficient air permeability. The important objective of reclamation should be the homogenisation of the reconstructed soil in order to achieve equally good soil structure and air conditions favourable for vegetation within the whole investigated area.
