| Abstract: | The broken processes of borehole bottom rocks under annulus coring or full face drilling, while various arranging patterns of multi-pieces down hole hammers are used, are compared based on the analyses of drilling in hard rocks by down hole hammers. The larger diameter coring method and the case study of coring by down hole hammers patterned in HC annulus are also introduced. |

| Keywords: | large diameter multi-pieces down hole hammer energy concentration burst annulus coring |
