充填孔反向注浆工艺的技术研究和应用实践
|
摘要
充填采矿法是业内高效、无废采矿的主要方法之一,可是,实际施工中,往往会因爆破掘进振动等的影响,巷道顶板在地表注浆过程中极容易出现浆液渗漏,导致注浆失效。随着环境保护意识增强,为保证充填孔孔注浆效果,充填孔孔底反向注浆工艺取得了较好的效果。
Filling mining method is one of the main methods for efficient and non-waste mining in the industry. However, in actual construction, it is often affected by blasting and vibration, and the roof of the roadway is prone to slurry leakage during surface grouting.Grouting is invalid. With the enhancement of environmental protection awareness, in order to ensure the grouting effect of filling holes, the reverse grouting process at the bottom of the filling holes has achieved good results.
