Abstract

The construction of underground mining facilities is of essential importance to the exploitation of mineral resources. Confirmation of this is the fact that the construction costs of main facilities occupy 40-60% of the underlying investments in the main construction and equipping. The main underground mining facilities are: shafts, drifts, raise, pump chambers, warehouses etc. This paper presents detailed analysis of underground mining facility - drift construction costs per individual working operations, following their change which depends on the rock type and profile size of underground mining facility, as well as possibilities of reducing these costs.

Keywords

Underground exploitation; drift construction costs; construction of drift
