Which term refers to the following definition: A horizontal tunnel drilled through a diamond pipe?

• A. Electronic retailer
• B. Drift
• C. Emplacement
• D. Digging out

Answer: (B)

Drift is the mining term for a horizontal passage through a rock or ore body, such as a diamond pipe. It serves as an access route at a specific level to reach and remove ore along the pipe. In diamond mining, a drift runs horizontally to expose and recover diamonds along the pipe, fitting the idea of a tunnel drilled through the pipe. Emplacement is a geological term referring to how and where the diamond-bearing pipe formed in the host rock, not the tunnel itself. Digging out is a general description of excavation and not the precise mining term. An electronic retailer is unrelated.
