| Abstract: | This article studies the outburst risk when uncovering coal in crosscut one of the third coal layer in mine No. 2 of Shi Zuishan mine area. According to the actual situations, outburst prevention measures, such as dense drilling, using high pressure water jet were designed to expand drilling and pre - supporting. After the measures were adopted, the outburst risk deceased obviously. All of these guarantee the safety of coal uncovering and excavation, and provide experience for similar working of coal uncovering in crosscut afterward. |
