PROCESS OF DEVELOPMENT OF STEEPLY DIPPING COAL SEAMS WITH POWERED SHIELD COAL-WINNING SETS

摘要

FIELD: mining industry. SUBSTANCE: process provides for extraction of coal in rill breakage face, delivery of coal over transportation furnace, attachment of ventilation furnace as shield face approaches haulage level, performance of inclined seam working and cross-entries, preparation for development of second strip with erection of shield complex in hole of airway horizon, performance of cross-entries with inclination when preparing every second strip, performance of transportation furnace under inclined crosscut distance between which is set equal to horizontal projection of breakage face. EFFECT: enhanced productivity. 2 dwg
