An overly expensive piece of survey equipment that is pushed into an underground cavity (void) by the errant surveyor. This $120,000Aus lemming is then left for half an hour, amongst a rain of 2 ton plus sized rocks in a bid to create a 3D model of the stope. The model therein created allows the engineer to 'reconcile' the stope, or compare a model as opposed to actual void shape. This task usually ends the surveyor getting blamed for a poor CMS, when in fact it is the engineers poor design and inexperience that has left half of the gold on the footwall of the stope.....
Go and get a CMS of the stope survey monkey, we think you marked out the rings wrong.....usual reply is: learn how to design rings and you will recover all the ore...fool

CM is abbreviation of the term "Certain Man". CM is a description of a rock bottom rated member of society due to their dull and foolish antics.
An example of a CM type of person would be someone who plays microstars like they are real players or collects sports games with the intention of not playing them.
