With the continuous mining of coal, many mine have entered the deep mining mine ranks. Many problems which caused by the deep mining, especially the mine rockburst has had a significant increase, and a more and more serious trend, this has seriously affected the safety production[1]. There are many rockburst factors, and by the mining process and mining, its leading factor was difficult to be determined during mining. However, analyzing the mining process, and researching the influences of mining process on rockburst, making effective means of monitoring, adjusting the recovery process parameters, there are practical significance on mine safety. Reserving stacks along the gob tunnel is a mining technique which many mining often used. The document conducted numerical analysis towards the vertical stress distribution in the stacks, and come to a conclusion about the mining technique influence to shock bump, which has provided the basis for the recovery process parameter adjustment. Practice has proved that the method is feasible. The results of the analysis have practical significance.
