The two methods are “Drill and Blast”, also called “Conventional mining”, and “Mechanical cutting”, also called “Mechanized mining”. This report gives a basic description of the commonly used mechanical cutting methods and the available equipment with the corresponding advantages and disadvantages is described. Furthermore the report will give a basic knowledge of underground coal mining and how a choice of mining method and mining equipment is made. The challenge for each mine engineer is to find the best mining method and equipment solution according to the local mine condition and the mine needs.
