FIELD: mining. ^ SUBSTANCE: method involves filling of the worked-out area to the boundary of upper level of ground water with construction waste close as to its composition to natural minerals with fractions of various size, layer by layer with further compaction of each layer, laying of drainage layer with construction waste with thickness of not less than 0.6 metre and with fraction size of 150-200 mm. At that, topographic mapping of the whole pit is performed, and as per its results there made is planning with extraction of sections representing geological natural monument and sections subject to further filling. At that, filling with construction waste is performed while cuts of deposits representing geological natural monument are kept free, and possibility of access to them, monitoring them and arranging the museum of the Earth is provided. The rest sections of the pit according to the planning are broken into zones and filled; at that, overburden rocks are laid on the drainage layer. Hill is formed in one of the zones with its further terracing. Burial places are built on terraces. Columbarium and crematorium rooms are built in the rest zones. Foundation bases of the above buildings are arranged in the following sequence: first, overburden rocks laid on drainage layer are levelled, and piles are driven to the design depth from planning level of the pit. Then, buffer pad from sand of average grain size is made without compaction and binding concrete is provided above buffer pad. Zones are separated from each other by means of artificially created three-dimensional soil shapes, and tracks and access ways are covered with natural or artificial stone. ^ EFFECT: reducing labour costs of recovery work. ^ 2 dwg |
