Equipment foundation and mine rock bolt system
A ground-disposed foundation mat. A pre-drilled, wooden block has a thru-hole, the thru-hole defined by a thru-hole inner surface and a hole diameter, the wooden block having an outer surface; a rod is power-driven through the thru-hole, the rod having a head top surface and a smooth outer surface, the rod having a lead end, the rod having an outer diameter equal to or slightly greater than the hole diameter of each of the thru holes, wherein each rod is held in place by significant friction between the thru-hole inner surface and the smooth outer surface of the rod. As such, the rod is adapted to remain held in place within the block even when subjected to a pull force of at least 3 tons.
