Аннотация
High-rate ore drawing with a single drawpoint requires stable structure of the horizon bottom in block caving of ore. Application of load–haul–dumpers (LHD) conditions longer spacing of drawpoints, which worsens quality of ore drawing under caved rock. Adequate structures of trench bottoms of ore drawing levels are developed for LHD systems. Relations are set between the limit spacing of drawpoints along the length of the trench and the height of the caved level to define mutual influence of the drawpoints.
