| 摘 要： | 本文以青海省某大型河谷型砂金矿特征为例,并结合其他已勘查过的河谷型砂金矿矿床特征分析,主张在砂金勘探中对小于可采宽度的矿体,除在施工中及时加密工程验证外,在储量计算时可用“边界米克值”衡量代替以“工业米克值”进行勘探线的矿与非矿判定,同时再配以“镶边”法处理较为合理。

| Abstract: | Taking a large valley placer gold deposit of Qinghai province as an example, com-bining with the characteristics of other explored valley placer gold deposits,the present paper putsfoward a reasonable method to handle the orebodies with smaller width than minable width dur-ing placer gold exploration,that is, besides infilling engineering test in time the cut-off grade canreplace the mining grade to judge whether the sediments on the exploration line is orebodies ornot and,at same time,the rimmed method can be used in calculation of reserves. |
