Summary: At an underground coal mine, a worker suffered a broken ankle when a slab of coal hit him. The slab was reported to be about 1 m high and 0.5 m thick and broke away from the upper rib.
Recommendations to industry: A section 195 notice was issued to the mine operator prohibiting mining activity at the location until a detailed investigation has been completed. Rib conditions and the suitability of installed support should be monitored on an ongoing basis. Any issues identified should have corrective actions planned
