METHOD FOR PROTECTIVE MINE WORKING WHILE DEVELOPING VERY DEEP MINERAL DEPOSITS

摘要

Usage: The invention relates to mining and can be used for the protection of mining in developing reservoir minerals at great depths. SUMMARY OF THE INVENTION method comprises performing excavation in the goaf lava after complete extinction sealing caving in it under the influence of the rock pressure. New therein that the production is carried out in a layer of destroyed roof rock away from the footwall providing their loosening by a value equal to the coefficient of loosening under evanescent state of these species. In this method, no construction costs in mined rock band the space for accommodating the track generation and recovery of its parts during the latter. ff with
