本文应用数理统计对新汶水砂充填砂仓容量的确定进行研究.作者在调查研究中收集了新汶四个矿十个砂井的采砂和充填量的统计资料,发现在该地区特定条件下采砂和充填量的随机波动,基本上符合皮尔森Ⅲ型分布规律,从而求出采砂的概率曲线充填的保证率曲线.根据概率乘法定理推求采砂和充填同时出现的概率,最后得到,在一定概率下所需的砂仓容量.
This paper uses mathematical statistics to determine the capacity of Xinwen water sand filled sand bin.The author collected statistical data of sand mining and filling amount of 10 sand wells in Xinwen four mines in the investigation and study and found that in certain conditions The random fluctuation of sand mining and filling volume basically accords with Pearson Ⅲ distribution rule, so as to get the guarantee rate curve of sand mining probability curve filling.According to probability multiplication theorem deduces the probability of simultaneous sand mining and filling, and finally obtains , In a certain probability of the required sand storage capacity.
