| Abstract: | The sound emission characteristics and the causes for incorrect prediction of the stope roof fall at Tonglushan Mine were analysed.On the basis of several tests and the understanding of the on site geological conditions,several single-channel sound emitters were used in multipoint supervision,as a result,the difficult problem of the position prediction of stope roof fall has been solved. |
