| 摘 要： | 通过建立井下巷道断面雷管爆破网络相似模型,分别进行煤体含水率与导电性能试验、井下串联爆破网络接地试验和雷管脚线联结方式影响试验。得出煤体含水率越大,电阻值越小;爆破网络中出现接地点,会产生接地电流降低整个网络中的电流;雷管脚线联结方式的不同直接增加整个网络的总电阻的试验结果,可为确定井下爆破雷管未爆原因提供参考。

| Abstract: | We establish the similar model of underground tunnel section detonator blasting network,through the testing of coal moisture content and electric conductivity,underground series connection blasting network grounding and the way of detonator foot line connection,these will influence the test.Then we can find that the greater the moisture content the smaller the resistance value;if the ground happen in the blasting network,it can produce grounding electric current to reduce the electric current in the whole n... |
