    摘要： A filling apparatus for a grouting system. The filling apparatus comprises a first fill tube and a second fill tube. The first fill tube is discrete from the second fill tube. The first fill tube is disposed for transporting resin mastic and the second fill tube is disposed for transporting initiator. A portion of the first fill tube has an inlet opening through which an injection quill extends interiorly and downwardly through the first fill tube. The injection quill is disposed for transporting inhibitor. This disclosure also relates to a method for adjusting gel time of a grouting system used for anchoring a reinforcing member in an opening, a grouting system for anchoring a reinforcing member in an opening, and a method for anchoring a reinforcing member in a mine.

    摘要： An anchorable mine support for anchoring in a borehole with resin or grout. The anchorable mine support comprises a tensionable elongate metal member and a sleeve disposed on at least a portion of the tensionable elongate metal member. The sleeve has a thickness of less than about 1 mm. A method of reducing frictional resistance between a tensionable elongated bolt and a hardened resin nut in a borehole formed in a face of a mine passage. The method reduces the frictional resistance between a tensionable elongated bolt and a hardened resin nut, thus improving the ability to tension a tensionable elongated bolt and stabilize a rock formation or structural body.
