Abstract

One of the most important places in the complex of production processes of coal mining are occupied by support and roof control in longwall faces. The work on support and roof control are associated with high labor and timber costs. The main means of reducing the cost of support and roof control is the wide introduction of mechanized support and metal organ walls. As industrial tests have shown, the best technical and economic indicators are obtained with organ walls OK and OKU‑150. This kind of support became the most widespread. As of July 1956, 182 faces in the Ukrainian Donbass and about 50 faces in the Rostovugol Combine were secured with the OK and OKU‑150 organ walls. By the end of 1957 it is planned to introduce this support in 600 faces in a number of basins of the Soviet Union.
