63_上10综放工作面为四周均已采完的“孤岛”工作面。由于受已采面开采及支承压力叠加作用的影响,顶煤极易破碎,掘进中曾出现局部高冒现象。应用煤岩化学加固技术后,有效地防止了顶煤大面积失控事故的发生。
63_ 上 10 Full-mechanized Caving Face is an “isolated island” working face that has been collected all around. Due to the influence of the coal mining and supporting pressure superposition, the top coal is very easy to be broken and the partial high-risk phenomenon occurred in the excavation. After the application of chemical strengthening technology of coal and rock, the occurrence of large-scale uncontrolled top coal accidents is effectively prevented.
