摘要

is an effective way to excavate to strike down without u0437u0430u0436u0430u0442u0438u044f material and device for implementing the method.the device is that the mechanism is located on the u0437u0435u043cu043bu0435u0440u043eu0439u043du043eu0439 blast cutting machines and provides the mechanism for the material outer layer and a its mechanism for the material inner layer and the outer layer provides the mechanism for the material for the material of the external layer, which sp u043eu0441u043eu0431u0441u0442u0432u0443u044eu0442 u0432u044bu0441u044bu043fu0430u043du0438u044e materialu0432u044bu0440u0443u0431u043bu0435u043du043du043eu0433u043e resulting from the impact of impactor for material internal layer from between the drums used for the outer layer material, and the / or completed with graduation hole, allowing the material u0432u044bu0440u0443u0431u043bu0435u043du043du043eu043cu0443 percussion impactor was used to impact the material inner layer, sleep blue lake,the mechanism for the material of the internal layer contains a material for the inner layer and the outer layer, the fit mechanism for material to u0443u0434u0430u0440u043du043eu043cu0443 mechanism for internal layer material for blast cutting and unloading. the device has the advantages of simple structure, advanced nature and reliable work.
