Most coal seams are too deep underground for opencast mining and require underground mining, a method that currently accounts for about 60 percent of world coal production. In deep mining, the room and pillar or bord and pillar method progresses along the seam, while pillars and timber are left standing to support the mine roof.

Adit | mining | Britannica

Where either a vertical shaft or an adit can be used to reach a mineral deposit, the generally lower cost of driving an adit, the saving in the cost of pumping water, and the ease of hoisting ore through the shaft dictate in favour of the adit. Consequently, adits as long as one to three kilometres (one or two miles) are often economically feasible.

Coal mining

Coal haulage, the transport of mined coal from working faces to the surface, is a major factor in underground-mine efficiency. It can be considered in three stages: face or section haulage, which transfers the coal from the active working faces; intermediate or panel haulage, which transfers the coal onto the primary or main haulage; and the main haulage system, which removes the coal from the mine.
