Dotěžení zásob štěrkopísků v korytě štěrkovny dobývacího prostoru Bohumín-studie

Abstract

The aim of the diploma work is the plan for completing the mining of glacilacustrine sand in Bohumín subglacial river bed in the Bohumín gravel pit. The most optimal mining technology was chosen from three proposed alternatives. It will enable to lower the existing mining profile of the 2 level by as much as 30 meters and thus also enable more rational mining of the reserved deposit. The work includes recalculation of available resources of the deposit. Based on stability expert opinions the work also outlines the problem of possible alternatives of increasing the mining depths in relation to securing of the protected objects on the banks of the mining lake. The thesis also tackles the possible alternatives of future exploitation of the location related to the supposed character of the originated area intended for recultivation. Conclusion gives brief technical-economical and ecological evaluation of the plan.
