Mining speed
The formula for miner mining speed is:

(mining speed)=(miner level)*(purity modifier)*(overclock percentage)*60

Purity modifiers; Impure = 0.5x, Normal = 1.0x, Pure = 2.0x.

With an un-overclocked Miner Mk 1 you will get the following mining speeds:

How to place a miner
A miner can be placed on resource nodes. To access a resource node simply harvest the "big stone" on top of it (is says "pure" when you look at it) by hand, it will unblock the resource node beneath it and the miner can be placed.
