Tubular bar support with explosion lock formation
Abstract
The application of rod support to combat rock heave in mine workings in Donbass mines has shown that conventional rod locks do not provide reliable anchoring in clayey rocks. Their pull-out forces during tests did not exceed 1–1.5 tons, which is completely insufficient for metal rods. Therefore, to combat clay heave in workings of mines in the Moscow Basin, the authors have proposed a metal tubular rod support.
