评价雷管(或炸药)引爆瓦斯的安全性,是指一种雷管(或炸药)与另一种雷管(或炸药)对引爆瓦斯难易程度而言,是一个相对的比较概念。鉴定煤矿用雷管(或炸药)对瓦斯安全性方法是利用试验巷道检验其引爆瓦斯的程度,从而比较其安全程度。试验的条件是将要比较的炸药放在发射臼炮内向充有9%甲烷的巷道里发射或把炸药悬吊在充有9%甲烷的巷道中爆炸。结果表明同样药量引爆瓦
To evaluate the safety of detonating gas by detonators (or explosives) means that a detonator (or explosive) and another type of detonator (or explosive) are comparative concepts that are relatively easy to detonate gas. Identification of coal mine detonators (or explosives) on gas safety is the use of test tunnels to test the extent of its detonation gas, so as to compare the degree of safety. The test was conducted on the condition that the explosives to be compared were fired in the firing mortar inside the tunnel filled with 9% methane or the explosives were detonated in the tunnel filled with 9% methane. The results show that the same dose of detonation tile
