The report brings the results of investigation the development of black pine (Pinus nigra) plantation situated on sandy substrate of the surfice coal mining soil. According to granulometric analyses the red sandy substrates by their constituents are similar to clay. Yellow substrate is of lighter content and it is similar to clayey sand; substrate in deeper layers is similar to sandy clay. The gray yellow sandy substrate, for its small share of total clay of 6-7%, belongs to pure sands. All these are light soils. But red brownish substrate on the contrary, has more total clay of 28,60-29,70% which affect better water - air regime and bigger microbe population. The difference in granulometric content and pedologic conditions were influenced the increment of growth, so that on red brownish sandy substrate the average heights are 141,70cm, on red substrate 108,25cm and on yellow substrate only 95,25cm. The recultivisation is not successful on gray white substrate with coal. For afforest recultivisation the best one is the red brownish substrate; it will be the best to be mostly represented on excavation site. Gray white sandy substrate with addition of coal must not be found on the surfice of excavation site, but can be layed down to the depth of 50cm.
