摘要
通过采用瓦斯涌出初速度及钻屑量指标法,介绍了如何在高瓦斯矿井煤巷掘进中进行瓦斯突出危险性预测。采取四位一体的防突技术,避免瓦斯突出造成危害。
This article through uses the gas to gush out the initial velocity and the drilling quantity target law, Introduced how carries on the gas prominent risk in the high gas mine pit coal lane tunneling to forecast,Avoids the gas prominently being brought to a successful conclusion the harm.
