On the control of slabs at under-floor hydrodemolition
Authors:
Abstract
To reduce coal losses during hydraulic mining of thick steeply dipping seams by the sublevel hydraulic extraction system, flexible metal floors are used, separating coal from the caved rock and, along with completeness of extraction, allowing coal extraction to be carried out without support in the stope.
