Cost Analysis in the Construction of Underground Mining Structures and Opportunities for Their Reduction

摘要

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