The Possibility of Increasing the Air Flow in the Stope S-144 "Trepca" Stanterg

Abstract

The stope S-144 as a system of exploitation it is applied and is applying the method of exploitation with filling from bottom upwards where for access to the stope respectively in benches has applied so called classical method with vertical objects (passage for people). In bench 5 has been changed the working principle being applied the approach in the stope by ramp method where it is changed the principle of drilling and loading (application of high productivity machines – Boomer and diesel mechanic loaders Toro and Wagner). The above mentioned stope for now possesses these mining facilities: 1) horizontal adit that connects the ramp; 2) shaft for filling of mining area where at the same time it is like air shaft, and; 3) passages for people where the one of them has already been out of operation while the other one serves as the pit for ore haulage of this stope. The current state of the shaft (raise) ventilation for the moment is considered as a sensitive and has great curves during the working phase encountering in soft rocks (schist) thus it made impossible the opening of vertical shaft where we concluded that there do not appear the major resistance and loss of the amount of air.
