| Abstract: | In this paper, the fault tree analysis is applied to the safety assessment of roof fall accidents in coal faces. Authors derive some formula for calculating the accident probability and risk rate of roof fall in coal faces. Authors present the primary research achievement for determining the safety indices and accident laws of roof fall in coal faces |
