英语百科

Rock burst

A rock burst is a spontaneous, violent fracture of rock that can occur in deep mines. The opening of a mine shaft relieves neighboring rocks of tremendous pressure, which can literally cause the rock to explode as it attempts to re-establish equilibrium. Rock bursts are a serious hazard; in South Africa, they kill roughly 20 miners each year. Rock bursts basically depend on the size and depth of the excavation.
