导水岩溶陷落柱的治理新技术

New Treatment Technology of Water-conducting Karstic Collapse Columns

山西某矿100302综采工作面发生了透水事故,因地制宜,创出一套井下静水控制注浆技术,对发育的岩溶陷落柱进行了彻底的治理,对工作面尽快复产回收提供了有力条件,并填补了以往注浆技术的空白。

According to the water inrush accident in No.100302 fully-mechanized driving face of some mine of Shanxi, a set of hydrostatic controlled grouting techniques in the pit is created. The method harnesses the developed karstic collapse columns thoroughly, provides the powerful condition for restoring production, and fills the gap of previous grouting technology.
