Improving Technical-Economical Performance at Praid Saline Way of Rock Salt Roadheader Mechanized Mining

Abstract Increasing the mining depth at Praid Saline and implicitly state of stresses strains determines an increase in dimensions resistance structures (pillars ceilings). Furthermore, seismic effect generated by detonation explosives contributes to degradation structures. In order reduce destructive drilling-blasting technology a proposal is made for implementation mechanized salt cutting which makes use roadheader. This article emphasizes technical-economical advantages exploitation from lower horizons New Sector, those with roadheader as opposed classical drilling-blasting.
