Energy and environmental engineering silly question

[t0mm02]

Hello everyone,

I am sorry if this question looks silly but my tutor has not replied yet and I need to work it out as soon as I can. Could someone tell me if they see any difference question 1 and question 2? Because I genuinely don't and it is driving me crazy. The assignment is about a coal mine and how to prevent emissions

1. Focuses on keeping the gasses still inside the mine.
2. Focuses on doing something with gasses out of the mine.

It sounds to me like they are differentiating between gaseous and particulate emissions.

Loading trains can raise dust. This might not be considered part of "mining operations".

Is "processing" included in "mining operations"?
