针对某露天矿山实际情况，结合粉尘污染扩散理论，应用函数拟合与数值计算的方法，对该露天矿钻孔、爆破、铲装、汽车运输、倾倒作业产尘点的源强进行测定与分析，研究不同粉尘源对总产尘量的贡献率。分析得到爆破作业的产尘贡献率最大为98．145％，除爆破以外汽车扬尘为最主要设备产尘源。
針對某露天礦山實際情況，結閤粉塵汙染擴散理論，應用函數擬閤與數值計算的方法，對該露天礦鑽孔、爆破、鏟裝、汽車運輸、傾倒作業產塵點的源彊進行測定與分析，研究不同粉塵源對總產塵量的貢獻率。分析得到爆破作業的產塵貢獻率最大為98．145％，除爆破以外汽車颺塵為最主要設備產塵源。

Based on the actual situation of one open pit mine ,the function fitting and numerical methods are combined with the dust pollution diffusion theory to measure and analyze the dust production points resource intension ,such as drilling , blasting ,shovel loading ,motor transport and dumping operation ,and the contribution rates of different dust sources to the total dust production are also researched .It is found that the blasting contributes 98 .145% of dust production and the motor transport is the second major source of mechanical dust production .
