Is there any video explaining how to do the African Mine Skip? I saw the WR run do it, but I'm not entirely sure how it is done.

Not to my knowledge I also have tried it a lot and dont think it is a available in the current patch on PC

Don't know bout the video but here. If you look at the pic there are 4 spots I have marked. Each of those spots correspond to one of the rocks that I have removed in the pic. Now how to remove the rocks? You need the left side for your screen to hit the corresponding spot and then move back to the left quickly and vola~ the rock has disappeared. A test runs from yesterday showing the trick being done in current patch.

I'm pretty sure I learned it from this video:

I know other people use different setups, but I'm not aware of tutorials other than this one. If you have additional questions, feel free to ask and I can try to answer, but I think the video is pretty exhaustive.

@Max_gentleman: I play on PC and it should definitely work, though it might be trickier depending on hardware specifications.

i was doing some homework on this skip too. the screen needs to hit the left most point of the screen while you jump back and then forth again as can be seen on this image:

Here's video of how to do it:
