摘要

the invention u043eu0442u043du043eu0441u0438u0442u0441u00a0 to the mining industry and is u0434u043bu00a0 mining blocks of natural u043au0430u043cu043du00a0. objective to obtain the correct form in the drive units u043fu0438u043eu043du0435u0440u043du044bu0445 trenches. u0434u043bu00a0 this ring u0444u0440u0435u0437u043eu0439 array length u043fu0440u043eu0445u043eu0434u00a0u0442 trench has two vertical u0440u00a0u0434u0430. u0440u0430u0441u0441u0442u043eu00a0u043du0438u0435 between them corresponds to the width of the trench.then along the entire length of the trench in the transverse direction u0431u0443u0440u00a0u0442 lines u0448u043fu0443u0440u043eu0432 intervals between rows equal to the difference between the depth of u0440u0435u0437u0430u043du0438u00a0 horizontal noah hobbing and its radius. after that, u043eu0441u0443u0449u0435u0441u0442u0432u043bu00a0u044eu0442 horizontal u043fu043eu0434u0440u0435u0437u0430u043du0438u00a0 and u043eu0442u043au0430u043bu044bu0432u0430u043du0438u0435u043c blocks with the help of mechanical u043au043bu0438u043du044cu0435u0432. this is u0434u043bu00a0 mill along the walls of the trench to a depth of u0440u0435u0437u0430u043du0438u00a0 horizontal milling machines.then move the cutters. in the horizontal plane to the opposite wall u0441u0442u0440u0430u043du0448u0435u0439. after the cutting of the milling machines in the vertical u0440u00a0u0434 mill along the walls of the trench are connected from the array. in u0448u043fu0443u0440u044b placed destructive means, and through them, destroy the wire between the u0448u043fu0443u0440u043eu0432u044bu043cu0438 u043eu0442u0432u0435u0440u0441u0442u0438u00a0u043cu0438. u043eu0431u0440u0430u0437u043eu0432u0430u0432u0448u0438u0435u0441u00a0 blocks out. 4).
