Investigation of the characteristics of pneumatic energy consumers
Abstract
About one-fifth of the coal in the Soviet Union is mined with pneumatic jackhammers, and the mechanization of underground work in the ore industry is carried out almost exclusively with compressed air power. In addition to jackhammers and drilling hammers, a lot of various mining equipment with pneumatic drive has appeared in the face and at the site nowadays. With the wide application of shield system of coal mining at powerful steeply falling seams, as well as the system of development by horizontal layers, the number of upward workings, which are used for ventilation, coal transportation, fixing timber, etc., is sharply increasing. For sinking of such workings the air-drilling machines are more and more often used.
