摘　　要：文章以跃进煤矿23130工作面下巷为例,利用插值法把巷道掘进期间的钻屑数据连接起来,获得整条巷道的煤粉量数据;再根据煤粉量、围岩应力、冲击地压三者之间的关系,给出了整条巷道不同区段的冲击危险等级。实践证明,预测的结果与事实相符。Taking No. 23130 coal mining face in Yuejin Mine as the example, the interpolation method was applied to connect the drilling cuttings data during the mine roadway heading period and thus the coal powder data of the full mine road could be obtained. Then base on the relationship between the coal powder quantity, surrounding rock stress and mine pressure bumping, the mine pressure bumping danger grade at the different section of the full mine roadway could be provided. The practices showed that the predicted results could meet the actual conditions.
