A SUGGESTION FOR THE PERMANENT SUPPORT DRIVE IN CONDITIONS OF CONSIDERABLE UNDERGROUND PRESSURE

Sažetak
In the conditions of considerable underground pressures 12 different technologies were applied during the drift driving in the lignite mine »Titovo Velenje«. The drift is driven largely through marly clays and tuffs with sandstone. The most of applied technologies of performance, especially in the areas with considerable pressures, have not given satisfactory results in view considering the realized dynamics of works, stability maintenance and the cross-section clearance diagram of the drift. The analysis of the used driving technologies and underground pressures serves fur the construction of permanent support, differing basically from standing rigid classical supports. The characteristics of a conceived support, in conditions of considerable underground pressures, enable the construction of a drift with the complete profile, the maintenance of planned working dynamics, the stability and safety of the drift which decreases the cost price for the built meter of the drift.
