Abstract

Horizontal mining facilities, such as pits, crosscutting drifts, longitudinal drifts etc., can be constructed in surrounding rocks, underburden or usually overburden, also in the ore deposit. The route of horizontal mining facilities primarily depends on: physical and mechanical properties of surrounding rocks and ore deposits, as on the thickness and way of providing the ore body, the construction costs and the projected mining method. It should be noted that within same types of rock exist zones with different structural characteristics, regardless where mining facilities will be constructed either in surrounding rocks or ore body. Different properties create a difference in stability of the rock material. Therefore, is essential for any rock type to determine its structural properties such as: discontinuity plane orientation, the degree of jointed on rock material, joint and joint family, as and stability of each block, located adjacent to underground facilities.
