Abstract

This paper presents the analysis of the construction of drift, as a horizontal mining facility. The 9 variants drift construction, in rock type lead-zinc ore were formed. Assumed length of objects in all variants was 1000 m '. The aim of this research was to determine the required time for construction of all variants and then to reduce it to the time required for construction of 1 m` per facilities. Based on analysis, two parametric functional dependents of construction time are determined in relation of uniaxial rock mass compressive strength and the size of the facilities` cross section.
