Based on the depth of the coal seam and the surrounding terrain, the decision of what type of mine to construct is decided. More or less all underground mines are not as much of 1,000 feet deep, but some mines reach depths of about 2,000 feet. As a rule, slope mines begin in a valley bottom, and a tunnel slopes down to the coal to be mined.
