SUBSTANTIATION OF VARIABLES OF PRESERVATION PROCESS OF DEVELOPMENT OPENING AT KUZBASS COLLIERIES UNDER CONDITIONS OF ACTIVE BULGE OF SOIL ROCKS

There the study objects are the flow schemes of guard and of preservation of development opening of collieries. The paper purpose is to ascertain the dependences of characteristics of system in the Support - Coal-Rock Solid Surrounding It on the set of natural and mechanical-and-mining factors for the creation of preservation process of development openings for their re-use under the conditions of active bulge of soil rocks, which provides the rise of exploitation efficiency of coal seams. The methodical principles for the substantiation of variables of preventive action on the coal-rock solid for the preservation of openings have been improved; the values of roof shifts and of soil bulge depending on the main natural and mining-mechanical factors have been ascertained. The recommendations for the comprehensive action on the rocks surrounding the opening have been worked out with the purpose of major decrease of negative manifestation of mine pressure. The quantitative variables of camouflet blasting process of soil and of microtorpedoing process of roof have been ascertained with regard to the geological structrure of containing rocks, to the serviceability of explosives. The flow schemes of preservation of development openings may be used at the collieries with the active bulge of soil rocksAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
