From the start, fall along the right side of the level, just to the left of the drones. Grab the wall and jump off to get the exit switch, jumping quickly toward the opposite wall to avoid the two floorguards. Jump up the left wall to the exit, using the bounceblocks. You may have to wait for a drone to get out from in front of the exit if you're not fast enough.
It's also possible to descend by falling from the start towards the left wall, and jumping off just above the lower mine, landing directly on the exit switch.
