Influence of man-made edaphotopes of the spoil heap on biota

The aim of the work is to investigate the influence of man-
made edaphotopes of colliery spoil heap on biota by bioindication method.
The physicochemical properties of edaphotopes were investigated:
humidity, substrate temperature, humus content at different intervals of
their depth and on different sections of the waste heap. The storage
technologies of mineral waste in the dumps disregard its further use and
transforming that occurs over time. It was revealed that on the northern
slope exposures the greatest amount of moisture was concentrated and
temperature regimes were acceptable for the activity of the soil biota,
which was proved by the largest amount of biomass. New dependences of
humus content in edaphotopes of the heap in different intervals of their
depth from biomass of humus-forming organisms were established. Slight
successional processes on the surface of the heap were observed, where
young flora began to develop. This positive phenomenon will contribute to
the humus of the genetic horizons and the development of tree and shrub
vegetation. Favourable conditions for the development of neo-terrain and
the formation of a new landscape in mining regions were confirmed.
