    This paper is a preliminary study in determining the capacity of sand bin in hydraulic filling at the Sin Wen Mine by the aid of mathematical statistics. Through an investigation on the statistical materials of the sand capacity for collecting and filling from ten sand bins in four mines at Sin Wen, the authors discover that the statistical fluctuation of such capa-city of sand under the condition at that area is fundamentally correspondent to the Pilson's distribution law type Ⅲ. From which the respective...

    This paper is a preliminary study in determining the capacity of sand bin in hydraulic filling at the Sin Wen Mine by the aid of mathematical statistics. Through an investigation on the statistical materials of the sand capacity for collecting and filling from ten sand bins in four mines at Sin Wen, the authors discover that the statistical fluctuation of such capa-city of sand under the condition at that area is fundamentally correspondent to the Pilson's distribution law type Ⅲ. From which the respective curves of probability and guaranty for collecting and filling are figured out. The probability of collecting and filling of sand oc-curring at the same instant can then be worked out in accordance with the theorem of proba-bility multiplication, and the needed capacity for a certain probability is thus obtained.
