ABSTRACT
At the current level of stope works intensification in coal mines, the task of timeous preparation of new production sites is extremely topical, one of the directions of which is to reuse the preparatory mine workings. This chapter considers two main perspective components of the technology for mine workings reuse. The first is to reduce the costs for maintaining mine working by involving in the work not only of border rocks, but also of more distant rocks in order to withstand the rock pressure forces. This direction has its own history already in terms of the wide application of load-bearing roof-bolting based on the resin-grouted roof bolt. The second component of the effective maintenance of reused preparatory mine workings is caused by the choice of rational parameters for their fastening (first of all) and then by subsequent protection (secondarily).
