砂矿勘探误差的原因已在许多资料中分析过了。但是,在实践中仍存在着较多的影响因素,所以在开采时,勘探的资料并没有得到证实。为了揭示勘探和开采结果之间的差异,需要研究可能产生误差的一切原因,并对它进行分类。砂矿勘探的可靠性在多数情况下取决于所勘探的砂矿床的地质构造的复杂性,以及人们对砂矿床地质构造一般特征的研究程度。每一个砂矿床都具有自己复 The causes of sand exploration errors have been analyzed in many sources. However, there are still many influencing factors in practice, so the exploration data have not been confirmed during mining. In order to reveal the difference between the results of exploration and exploitation, all the possible causes of the error need to be studied and classified. The reliability of sand exploration depends in most cases on the complexity of the geological structure of the sand deposits explored and on the extent to which people study the general characteristics of the sand deposits. Each sand deposit has its own complex
