Question:
The term “Powder Factor” refers to
The term “Powder Factor” refers to
Show Hint
A higher powder factor indicates that more rock is broken for each unit quantity of explosive, implying better blasting efficiency.
Updated On: Jul 14, 2026
- Volume of explosive per drill hole
- Volume of rock broken per unit explosive
- Volume of rock broken per explosive
- Weight of explosive per cost of explosive
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Recall the definition of powder factor.
Powder factor is a measure of blasting efficiency and is defined as the amount of rock broken for a given quantity of explosive.
Step 2: Write the expression. \[ \boxed{ \text{Powder Factor} = \frac{\text{Volume (or mass) of rock broken}} {\text{Quantity of explosive used}} } \] Thus, it represents the \[ \boxed{\text{Volume of rock broken per unit explosive}.} \] Therefore, \[ \boxed{(B)} \] is the correct answer.
Step 2: Write the expression. \[ \boxed{ \text{Powder Factor} = \frac{\text{Volume (or mass) of rock broken}} {\text{Quantity of explosive used}} } \] Thus, it represents the \[ \boxed{\text{Volume of rock broken per unit explosive}.} \] Therefore, \[ \boxed{(B)} \] is the correct answer.
