Features of the Technology of Forming an Artificial Mass in the Roof Rocks Above the Recovery Room

Abstract

the paper presents a technology of creating a backfill massif above the re covery room in order to prevent roof rock caving in it. lining parameters for a wide (10.5 m) backfill chamber situated within roof rocks are determined. Backfill material type and pipeline parameters are justified. Polymer pipe application within backfilled zone is offered. Stoppings and backfill blocks timbering parameters are calculated.
