为了解决採矿场利用人工刻槽取样法效率低、配合不上工作需要的问题,第一铜矿採矿场已使用凿岩机点採试样法代替人工刻槽取样。使用结果证明:效率顯著提高,准确度也合乎要求,值得向各单位介绍,以便研究推广。但必须指出:如何根据各种矿体的倾斜、厚度和金属分布的均匀程度确定打眼的位置、深度、排列距离和方向以及二者相互关系等,目前尚未得出一定的规律。因此各单位应该根据自己单位矿物矿体的具体情况,通过实际的试验研究工作加以解决。
In order to solve the problem of inefficient use of artificial groove sampling method in mining field and not meeting the requirements of work, the first copper mining field has used the sampling method of rock drill point sampling instead of artificial groove sampling. The use of results show that: significantly improve efficiency, accuracy is also required, it is worth to introduce to all units in order to promote research. However, it must be pointed out: how to determine the location, depth, arrangement distance and direction of drilling holes and the relationship between the two according to the inclination, thickness and distribution uniformity of various ore bodies have not yet got a certain law. Therefore, all units should be based on their own specific situation of mineral ore body, through practical experimental research to be resolved.
