Abstract: 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.

Key words: Crack alteration,Collapse,Water inflow,Grouting reinforcement,Permeation grouting,Fracturing grouting
