| Abstract: | Basing on the dynamical phenomenon in 0521, risk of outburst in 0521 of 10 level of Majiagou coal mine is analyzed under the methods of the energy of initial releasing gas, the aggregative indicator and the remained gas content. The results indicate that outburst will occur under the condition of rock cross-cut coal uncovering in 10 level of Majiagou coal mine. |
