Návrh na rozšíření těžby v lomu Libodřice

Abstract

In the presented work, a project on the enlargement of extraction in Libodřice Quarry is elaborated. In this quarry, building stone – amphibolite - is extracted. Crushed aggregates are produced here. Nowadays, the base of opencast mining in the Libodřice Stone Quarry is permitted up to the level of 290,0 metres above the sea level. The enlargement of the quarrying suggests the utilization of the supplies up to the level of 260,0 metres above the sea level, and the areal expansion off the limit of the mined area which has currently been permitted. The utilization of the supplies is proposed in the quarry with six mining benches with one stripping bench, on the plots in the ownership of the mining organization and on the plots of other owners. In the first part of the work data on geology, hydrogeology, and quality characteristics of the deposit are processed. The following parts are focused on the methods of extraction, the capacity of the supplies, drainage of the stone quarry, technology of treatment, safety measures and protecting of health at work. Another part deals with the possibility of remedial measures and the reclamation of the land after the termination of the excavation, and the quantification of the costs of both remedial measures and the reclamation of the land. In the conclusion, technical-economic and ecological assessment of the proposed project is carried out.

The solution of the problem is also demonstrated in the maps in the appendix.
