摘要
近距离煤层群开采时,回采工作面的支承压力经常给附近煤岩层的巷道带来采动影响,因而在实践中要摸索在不同区域和不同煤层开采时支承压力的分布规律及应力传播角的实际情况,为工程设计提供可靠的依据,合理避开支承压力对巷道的影响。
Close-up coal mining, coal mining face of pressure from the regular support to the rock of the tunnel near the coal mining brought about by the impact, which in practice to find out in the different regions and different coal mining when the pressure of supporting the distribution and dissemination of the actual situation of stress, For engineering design and provide a reliable basis for reasonable support to avoid pressure on the roadway.
