The depth of the auxiliary shaft of red coal mine is 1002.5m constructed by Ningxia Yinchuan Baofeng Energy Group Limited Company, whose shaft surface soils and bedrock use freezing method construction, wellbore below 680m uses ordinary construction method, borehole water uses face pre grouting method. In the process of grouting, the first grouting section single hole discharge up to 60m3/h, after pit shaft’s grouting through high pressure working face, it through the aquifer safely and achieves the shaft digging.
