A US Bureau of Mines method to precondition rocks to prevent rock bursts is presented. The approach uses deep drill holes from a mine opening in a radial pattern in the vein and load and blast to fracture the rock prior to production mining. The method was successfully tested on a sphalerite-galena vein in a hard gangue of quartz and quartzite at the 7700 level of the Hecla Mining Company's Star Mine in Burke, Idaho. (JMT)
