Question

question 9 of 10
a student drew the following flowchart.
blasting → collecting → hauling → crushing
which process is shown?
a. coal burning
b. surface mining
c. crude oil refining
d. hydraulic fracturing

Explanation:

• Coal burning: Involves combustion, not the sequence of blasting - collecting - hauling - crushing.
• Surface mining: Typically starts with blasting the overburden and ore body, then collecting the fragmented material, hauling it to a processing area, and crushing it for further treatment.
• Crude oil refining: Deals with processing liquid crude oil, not the solid - material - handling steps shown.
• Hydraulic fracturing: Focuses on fracturing rock formations with fluid pressure, not the general material - handling sequence.

Answer:

B. Surface mining
