Mining has long been a dangerous line of work, however, it can and should be done safely, using modern procedures. Those who prefer for miners to place their lives on the line, probably do not want to spend the money needed to protect the safety of miners. People can be very greedy.

Quarrying is complete by the type of rock the miners want, for example if they want cement they might use explosives to break the quarry wall into small bit of rock as cement can be sold in small pieces but if the miners want granite for a kitchen countertop they will drill holes in the rock, long distances apart. Dynamite will be packed into these and the blast will separate large slabs of granite that will be 'sliced' with wire saws. There is one other way to quarry such as drilling holes, blasting dynamite to make an opening, and then blowing in compressed air [or water] that splits the rock.
