METHOD FOR MINING STEEPLY INCLINED ORE VEINS

摘要

The invention relates to underground mining of steeply dipping conductors, partially placed in the area of ​​marginal natural underground cavity. The aim - increase of productivity and reduction of ore bypass dilution when developing veins valuable mineral, partially located in the area of ​​marginal natural underground cavity. steeply dipping development lived valuable mineral effected substage. Lower substage formed in natural cavities zone. Between substage ore pillar form. Intermediate field generation extend in hanging conductor side than on natural cavity. Za- magazinirovannuyu upper substage ore transferred to a cavity of the lower substage t refinement and making stocks lower substage in descending order with the selective recess mineral and subsequent descent to its mechanized haulage horizon. Extinguishing ore pillar is produced out after completion of the recesses valuable mineral. 1 ZP f ly-3-yl. ate with
