The lining of shaft in construction of mine with large mount of water is a difficult project , especially the section with rich water and soft broken rock brings a lot of risk and uncertainty to the construction .How to ensure the smooth progress of the project becomes a major problem to the infrastructure mining .The Nan Li-zhuang iron mine dugged the rock breakage and rich water section smoothly using long inspector note and advance small duct grouting construction technology .This construction technique determined the number and arrangement of exploring and grouting holes , the depths of exploring and grouting holes and the digging depth , grouting parameters , and the control of grouting parameters , the control of grouting process , advanced small pipe construction parameters , the strengthening methods of mini tube , etc.Through constructing long exploring and grouting and constructing small catheters, the excavation work progressed smoothly .
