Prospects of application of flexible technology for mining alluvial deposits of permafrost rocks
Abstract
The paper considers the issues of perspective application of pneumatic ballast support in flexible technological schemes of perennially frozen rock formations mining by drilling and blasting method. Recommendations on determination of optimal parameters of bottom-hole cleaning are given.
