Sure, here is the walkthrough for the second room:
• You find yourself in another part of the diamond mine. Start by clicking on the gauge, Green=5, Yellow=7, Red=11. Now click the crate and adjust the dials to match the numbers, think of it like a clock. After the crate is open, take the dynamite. Set the dynamite next to the big rock on the left. Click the escape pod to look inside. Take the empty bucket. Look inside the compartment on the left, take the lighter you find inside. Use the lighter to light the dynamite, then use the empty bucket and fill it with coal from inside the hole. Click the panel below the gauge and add the coal to make a bigger fire. Next click the pipes on the right to move them and find a screwdriver. Take the screwdriver and click on the drill. Use the screwdriver to remove the panel and take the fuse you find inside. Click the escape pod to get inside and put the fuse into the slot on the panel. Then click the green button to escape.
