礦工

矿 = 广 + 石 : Karl Koala (ku) got a new job at the coal mine (矿) in the anglepod's bathroom (ang4). The entrance to the tunnel lies quite high, so every time Karl brings out another coal stone (石) he attaches it to a small parachute (广) and lets it fly down to the floor.

工 = 二 + 丨 : Mnemonic symbol: a steel beam, since 工 looks like the cross section of a steel beam.

Gitta Giraffe (gu) is working a shift in front of the engine ((e)ng1). Her job is to melt dinosaur bones (丨) so that they can be disposed off easily. To melt the bones, she is shorting a huge capacitor (二) with a steel beam (工) which consequently heats up to a bright glow. Using the glowing hot steel beam she can melt the dinosaur bone easily.
