Cable bolt structure and related components

In combination, a cable length having a proximate end and also a remote end for securement within mine roof strata borehole;

• a threaded tubular member disposed over at least a portion of said cable length and having a threaded proximate end and a remote end, said tubular member having a first open interior of a first transverse size proximate said proximate end, a second open interior of smaller transverse size proximate said remote end, and a conically tapered seat interposed between said first and second open interiors;
• jaw means initially disposed at and fitting in said tapered seat and gripping said cable length;
• and nut means threaded onto said tubular member for yieldingly tensioning said cable in advancing said jaw means beyond said seat in an interference-fit, pressure bubble relationship with respect to said threaded tubular member at said second open interior thereof.
