Abstract

An adjustable yield rock bolt that comprises an elongated tensile support member that interacts with at least one gouging member and a receiving member capable of receiving the elongated tensile support member and hold the gouging member segment there between, wherein the elongated tensile support member extends beyond the receiving member a length that corresponds to a predetermined amount of yield before ultimate failure. The bolt has adjustability by allowing for controlled yield by gouging of the elongated tensile support member for any length of displacement.

Claims (2)

1. An adjustable yield rock bolt apparatus comprising:
an elongated tensile support member;
at least one gouging member, wherein the gouging member has an interference fit with the elongated tensile support member during gouging;

a receiving member capable of receiving the elongated tensile support member, the receiving member having at least one perpendicular retaining guide therein to movably couple the gouging member against the elongated tensile support member, and wherein the elongated tensile support member extends beyond the receiving member a length that corresponds to a predetermined amount of yield before ultimate failure.
2. An adjustable yield rock bolt apparatus comprising:
an elongated tensile support member;

at least one gouging member, wherein the gouging member has an interference fit with the elongated tensile support member during gouging;
a receiving member capable of receiving the elongated tensile support member and movably coupling the gouging member against the elongated tensile support member, the receiving member including a hole perpendicular to the elongated tensile support member running from the outside of the receiving member to the inside of the receiving member, and wherein the elongated tensile support member extends beyond the receiving member a length that corresponds to a predetermined amount of yield before failure.
