【Abstract】 In the coal mining face, the pollution of coal dust not only menaced the coal mining production , but also harmed the workers’ health. this paper introduced a coal dust extraction which used in the coal mining face. For the optimization of the extration’ s property, a measure system is designed . Applying the orthogonal analytic method, the best structure of the extration is found.更多还原
