Abstract:In a mine shaft sinking with a mine shaft drilling ,a deep mine shaft ,large diameter of the shaft ,complicated geological conditions ,multi reaming required ,large quantity of the drilling mud re-quired ,long flushing circulation time and difficult adjustment of the drilling mud parameters would cause a low drilling rate.A separated drilling mud system applied to the temporary support would easi-ly have a bit balling ,expansible and shrinkage ,poor stability of the drilling mud ,large quantity of drill-ing mud abandoned problem and others.According to these problems ,countermeasures to solve drill-ing mud technical problems of the mine shaft drilling were provided .The countermeasure would be a restrained mud system applied ,development of a low solid phase or no solid phase drilling mud ,ration-al selection of the drilling mud parameters ,introduction of the drilling mud additive from the petrole-um industry and mud consolidation technology as well as the comprehensive utilization and others .The drilling mud technology from the petroleum industry could be a technical support of the mine shaft drilling mud and the introduction would be very necessary.
