Uvođenje fiberglass sidara sa dvokomponentnom smešom u tehnološki proces jame rudnika 'Rudnik'

Abstract

 This paper presents, in brief, principles of the underground rooms supporting by the fiberglass rockbollts, in combination with the two-compound mixture. This type of rockbolts was successfully introduced in the 'Rudnik' mine technological process, with excellent results related to the application, installing, breaking load and, especially, for the employments working safety. Knowing working conditions in the selected part of the 'Rudnik' underground mine, as well as defined mining method, the conclusion that fiberglass rockbolts with two-component resin are most suitable for application, was made.
