摘要 |
The enhancement of rock fragmentation and rock excavation by neutralizing the rock surface charge with respect to the drilling, tunneling, cutting, grinding, or polishing fluid. Water-soluble, high-molecular-weight, nonionic polymers are employed to neutralize the surface charge on the rock, thereby promoting increased drilling, cutting, tunneling, grinding and polishing performance resulting in increases in drilling, tunneling, cutting, grinding and polishing penetration rate, extensions in bit, cutting tool, grinding media, and polishing tool life and dust suppression.
