Abstract
The results of the research showed that hydromorphous soils prevail on the territories adjoined to waste heaps. Swampy meadow and sod soils were defined. During investigation of swampy meadow soils it was determined that the soil is humused at a considerable depth. The soils are saturated with the bases. According to granulometric texture it is sandy loam soils, but with depth go to the middle loamy soils. The analysis for labile forms of heavy metals showed that in these soils the content of investigated heavy metals does not exceed the maximum allowable concentrations, except for lead. The amount of humus in sod soils sharply decreases with depth, the reaction is close to neutral. This soil is of slightly heavier granulometric texture. The content of labile forms of heavy metals doesn’t exceed MACs, except for lead.

During investigation of swampy meadow soils it was determined that the soil is humused at a considerable depth, the content of humus at this depth is 1.75% (Table 1), and at a depth of 102 cm the amount goes down to 0.36%
Summary
Lviv-Volyn coal basin was created for over 60 years ago in one of the best places in Western Ukraine - the recreation zone. Novovolynsk mining area is located in the northern part of the basin and is one of the most environmentally problematic areas. Ecological and hydrogeochemical studies of the surface content of the waste heaps of the Novovolynsk mining area are described in papers [1, 2]. A number of recommendations for recultivation of disturbed lands in coal mining regions were developed [3,4,5]. Exploration, extraction, processing and use of mineral resources is accompanied by irreversible direct and indirect changes in the environment, which leads to the formation of disturbed lands of different types, scales and genesis [7, 8]
