<p>A resin bonded mine roof bolt (10) having an elongated rod with a first end (14), a second end (16), and a resin control surface (24) positioned on the rod between the rod first and second ends. The resin control surface has a channel (30) extending along the length of the bolt for distributing resin and interrupted spiral threads for mixing resin. When installed in a mine roof bore hole with curable resin, the resin control surface mixes the resin and partially fills the bore hole to minimize the amount of resin needed to anchor the bolt.</p>
