Epiroc donated a Ground Support Pull Test Kit and Swellex bolts to the Montana Tech mining engineering program for students to test the bolts.
Sleeves will be used on the bolts to qualify the critical bond length of Swellex bolts under forced displacement without loss of bolt integrity. The Pull Test Kit will be used in testing the bolts’ load and deformation characteristics.
An Epiroc team provided installation and hands-on training support. The school will publish the findings.
Epiroc said the donation was to help future miners understand the limitations and capabilities of Swellex bolts. “It gives Epiroc additional insights so we can continue our ongoing quest for improvement in mining,” said Shawn Cheney, business line manager, rock drilling tools, Epiroc.
