Experimental Study of Decouple Coefficient of Compound Uncoupled Charging Constitution

摘要：

In the process of tunnel driving, if we use common charging constitution, blasting makes larger vibration damage on the surrounding rock, so the cost of laneway supporting increases, and the high temperature of blasting gas can cause gas and coal dust explosion. The author considers wrapping liquid medium (water or salt water) around the powder pouch then composes a compound uncoupled charging constitution. This charging constitution can reduce the blasting gas temperature and the blasting vibration damage. The author design the experiment to contrast the result of reducing temperature and vibration, then obtain the best decouple coefficient is 3.
