摘要:
A rotary dry drilling system comprises a surface mounted drill having a drill bit and a drill bit driver rotationally connected by a hollow drill string. There is included core sample capture means adapted to travel from the head of the drill string to the tail of the drill string. The system also comprises an auger for removing cuttings from a comminution zone and cuttings fluidization means to facilitate transport of cuttings from the comminution zone to the auger. Once the cuttings are removed by the auger they are collected and transported to the surface for disposal.
