- Abstract:
- A new type of bits called abrasive water jets bit can solve the problem that the speed is slow in hardrock drilling. The analysis of working principle for abrasive water jets bits shows that the efficiency of breakingrock by abrasive water jets bit is limited by punching speed affected by the structure of nozle.The main pa-rameters of affecting punching speed were studied by uniform design and numerical simulation.The optimumstructure parameters of nozzle and experimental parameters were determined.There are interactions betweenpressure,abrasive concentration with structures of nozle.Laboratory experiments show that the drilling speedby optimized abrasive water jets bit is 1.57 times faster than original three wings bit,1.25 times larger thancontrol group 1 and 1.18 times than control group 2,which shows significant advantages in hard rock drilling.
