    Other limited signaling systems such as bells or lights in shafts or along haulage systems existed but were limited in extent and in messages able to be sent. The use of longwalls led to the development of voice communications using speaker sets spaced across the face area (generally known as "DAC" systems). Such systems are now commonly utilised on conveyor belts throughout the mine.

    Mine Shafts an overview ScienceDirect Topics

    Conventional mining (also called cyclic mining) involves a sequence of operations in the order (i) supporting the roof, (ii) cutting, (iii) drilling, (iv) blasting, (v) coal removal, and (vi) loading. After the roof above the seam has been made safe by timbering or by roof bolting, one or more slots (a few inches wide and extending for several feet into the coal) are cut along the length of the coal face by a large, mobile

    Disused Mines and Shafts Health and Safety Authority

    Disused mines and shafts can be a major problem in many parts of Ireland. In the past, a common practice was to close mining sites, with little consideration given to the need to make these sites fully safe. With better regulation and the existence of the Environmental Protection Agency it is hoped that this practice is a thing of the past.

    Drifts/Inclined Shafts Introduction underground COAL

    Drifts/Inclined Shafts. The angle at which a drift becomes an inclined shaft is somewhat subjective, but there is some agreement that anything above 30 o to the horizontal is a shaft, not a drift. A major advantage of drift or inclined shaft access versus vertical shaft access is the ability to move large volumes of equipment, materials and
