Abstract
A mixing delay device for use with tensionable cable bolts wherein the mixing delay device compresses or is uncompressed in response to a compression force applied to the mixing delay device, wherein the mixing delay device increases resin mixing time, provides a visual indication of tensioning, and helps to reduce de-tensioning of the tensionable cable bolt.
