多种复杂地质条件下注浆加固技术研究

Study on Grouting Reinforcement Technology under Various Complex Geological Conditions

针对裂隙蚀变带大而宽、涌水量大、岩体破碎等多种复杂地质条件影响下的井巷掘进问题,以西石门铁矿北区深部开拓工程为例,在分析注浆工艺特点的基础上,考虑矿山地质条件及施工条件,提出了充填、渗透、劈裂联合注浆的整体方案,较好地满足了复杂地质条件下的稳固施工需要,适应了不同类型的施工需求,保证了深部开拓工程的顺利实施。

Aiming at the problems that complex geological conditions such as large and wide fissure alteration zone,large water inflow,rock fragmentation and so on affect the excavation of shaft and roadway,taking the deep development engineering in the northern area of Xishimen Iron Mine as an example,considering the geological conditions and construction conditions of the mine,the overall scheme of combined grouting of filling,infiltration and fracturing is put forward,the requirements of the stable construction under complex geological conditions,besides that,the scheme proposed in this paper adapts to different types of construction requirements and ensures the smooth implementation of deep development engineering.
