Cable bolts utilization in thick seam mining

, 2014
On the basis of different field and laboratory studies, a mining method called „cable bolting based thick seam depillaring“ has been developed CSIR-CIMFR to meet the technical challenges arising during underground extraction of a thick coal seam of ...

Cable-bolting-based semi-mechanised depillaring of a thick coal seam

, 2001
Based on simple rock mechanics principles, the idea of using a grouted steel rope under tension for supporting a high roof as well as an overlying coal band, and to improve the safe span of overhanging strata near the goaf edge for semi-mechanised ...
