Rock Removal Rate
Drilling rock removal rate, abbreviated as \(q_r\), is the efficiency at which rock material is removed through drilling operations.
Rock Removal Rate Formula |
||
\( q_r \;=\; \dfrac{ b_d^2 \cdot R }{ 11000 } \) (Rock Removal Rate) \( b_d \;=\; \sqrt{ \dfrac{ q_r \cdot 11000 }{ R } } \) \( R \;=\; \dfrac{ q_r \cdot 11000 }{ b_d^2 }\) |

Symbol | English | Metric |
\( q_r \) = Rock Removal Rate | \(ft^3 \;/\; min\) | - |
\( b_d \) = Bit Diameter | \(in\) | - |
\( R \) = Penetration Rate | \(ft \;/\; hr\) | - |
