method of passing the mountain mine

摘要

1.method of passing mines, including partitioning and drilling of the u0448u043fu0443u0440u043eu0432 entered in top right polygons and compensation wells in t my anus, crossing their u0434u0438u0430u0433u043eu043du0430u043bu0435u0439, u0437u0430u0440u044fu0436u0430u043du0438u0435 u0448u043fu0443u0440u043eu0432 explosives and explodium in sequence, and the fact thatin order to reduce the unit volume of drilling and explosive materials through the use of explosives and propellants u0448u043fu0443u0440u043eu0432u044bu0445 u0448u043fu0443u0440u043eu0432 ranking given the tensions in the u0440u043du043eu043c array, polygons, u0440u0430u0437u043cu0435u0447u0430u044eu0442 as u0440u043eu043cu0431u043eu0432 which lie in two mutually perpendicular planes passing through the diagonal u0440u043eu043cu0431u043eu0432, one of which x coincides with the direction of the maximum stress in the array.and another with the direction of the minimum voltages, large diagonal previous y are less u0434u0438u0430u0433u043eu043du0430u043bu044fu043cu0438 onward, with the first two u0448u043fu0443u0440u0430 on fi to initiate their u0448u043fu0443u0440u043eu0432u044bu0445 charges placed on top of y with less diagonal direction which coincides with the direction of the maximum u043du0430u043fu0440u044f the provisions in the u043cu0430u0441u0441u0438u0432u0435.2. method for p.1, a fact that the removal of nodes from the intersection set of y u0434u0438u0430u0433u043eu043du0430u043bu0435u0439 u0432u044bu0440u0430u0436u0435u043du0438u044fu0433u0434u0435 d is the length of u043fu0440u043eu0442u0438u0432u043eu043bu0435u0436u0430u0449u0435u0439 diagonal m; d is the diameter of the u0448u043fu0443u0440u043eu0432, m; u03c3u0432u0435u043bu0438u0447 ing the crush strength of the loaded mass, mpa.
