Increase of productivity and decrease of costs of a manual labour, maintenance of operation of development, increase of safety of activities. The method of development of the technological schemes both projects drifting and repair of mountain developments is rated - analytical. Bench tests. Is developed and the final edition DD "Sputtering concrete strengthen is introduced fix also hardening of rocks in a zone of inelastic deformations. Obtaining of rapid-setting structures with the active components. The instruction 12.04.005-99 ". In DD the normative references, basic position, requirement to initial raw material and final production, equipment and metrological to maintenance are established area of application rapid-setting knitting. Stipulated DD unified and not much power-consuming the technology of obtaining of rapid-setting structures is based on use man-caused of products (burnt a rock, scraps coal-concentrating DD is authorized Ministry of a coal industry (order 282 from 21.06.99) and is entered into an operation since 012.10.99. Decrease of the cost of attachment and hardening of rocks on 30-40 of %, reduction of terms of erection fix in 6-8 times, decreasing of the consumption of metal on 10-15 of %, energy- and expeditures of labour on 20-25%.
