摘　　要：利用其积累的丰富的探矿工程数据与采矿工程数据,总结了13号脉各工程品位与厚度的变化规律;根据矿床地质特征,解释了品位与厚度变化规律原因;结合目前矿田内找矿与采矿实际,提出了品位与厚度变化规律的实践应用。研究结果表明,哈达门沟金矿田品位变化规律为,品位局部稳定,随机突变,不均匀、不连续变化;厚度整体稳定,随机渐变,均匀连续变化;品位变化与厚度变化不具有相关性。造成品位与厚度如此变化规律的原因为,两期成岩,一期成矿,二者共同造成了这个结果。Based on the rich data of exploration engineering and mining engineering,the change regulation of grade and thickness of No.13 vein project is summarized in the paper.According to the geological characteristics of the mineral deposit,the change regulation of grade and thickness is explained and its practical application is put forward on the basis of the current prospecting and mining practice in the ore field.The research results show that the change regulation of gold grade in Hadamengou gold ore field is that the gold grade is locally stable,random sudden change,uneven and discontinuous;the ore body thickness is stable overall,and gradual changing randomly,evenly and continuously;there is no correlation between grade change and thickness change.The change of them is caused by two stages of diagenesis and one stage of mineralization.
