| 摘 要： | 爆炸冲击波在巷道内的传播规律,一直是采矿科学中的重要课题。由巷道现场的测试结果可以看出:随着测点与爆源距离的增大,二次爆炸冲击波与首次波的压力比不断地增加,在一定情况下,其比值可大于1,同时二次波与一次波的峰值间隔在不断地缩小,波的正压力时间加长。小药量的实验结果在一定的程度上也较能真实地反映实际爆炸作业时的情况。

| Abstract: | Spreading law of explosion impact wave in lane has been an important research topic in mining. The field testing results show that the pressure ratio of the second explosion impact wave to the first wave increases constantly with the increase of the distance from the testing spot to the explosion source. In certain circumstances, the ratio may be over one At the same time, the peak interval between Wave Two and Wave One reduces constantly and the positive pressure time of wave is prolonged. To some extent, the less--gunpowder experiment results can authentically reflect the practical situations of explosion operation. |
