| Abstract:The mechanical characteristics of the three wing back reamer used in guided boring in difficult formation is examined. The formula for calculating the optimum cutting angle in different rocks is deduced with the optimum angle obtained. The structural type of the back reamer is furthur optimized to provide necessary mechanical calculation basis for optimization of back reaming in guideel boring. |
