摘要：

The paper discusses possibilities of application of mined coal with different carbonization degree as a filler of polyethylene and polyamide. Mechanical properties and surface resistivity of polyethylene and polyamide filled with two different mined coals are presented. Achieved results indicate that influence of introduction of mined coal into polyethylene and polyamide is similar to the influence of mineral fillers. Additionally mined coal causes essential surface resistivity decrease of polyethylene.
