Head Svyeshnikov Igor Arkadijovych, Registration Date 11-10-2000 Organization V.Bakul Institute for Superhard Materials popup.description2 The object of researches - the rockdestruction tool and executive organs of mining machines. The objective of operation - development and implantation of constructions of the rockdestruction tool and executive organs of a new technological level of a heavy type entry-driving machines and modern stoping equipment, including plough plants used in a coal industry of Ukraine. Methods of researches - analytical and experimental definition of rockdestruction tool design data and parameters of rock destruction.The program of account of a stress-strain state of breed in an outcome of effect of a single cutter and executive organ of a entry-driving machine is developed. The mechanical contact of a cutter to breed in working order was taken into account by the using of appropriate contact conditions. With use of the theories of a limiting state the size of destruction zone of breed in an outcome of operation on it of a single cutter and volume of desroyed breed in an outcome of operation of the executiv e organ of a entry-driving machine was calculated..
