我们对采样、加工、化验工作(以下简称采加化工作)在地质勘探工作中的重要性的认识,并不是一开始就明确的,而是在实际工作中,碰了不少钉子,吃了不少苦头以后,才逐步明确和提高的.例如,1979年我公司在保德天桥铝土矿区地表采样时,竟然在风化面上刻槽取样,造成200多个样品中SiO_2的含量比实际(新鲜面上的样品)偏高0.74~2.1%,Fe_2O_3偏低4.28~5.41%,致使全部样品报废,不仅造成了经济上的损失,而且影响了矿区的评价进度.再如,在这个矿区用400×400米间距钻探时,见矿情
Our understanding of the importance of sampling, processing and laboratory work (hereinafter referred to as the “mining work”) in the geological exploration work has not been clear from the very beginning but has touched a lot of nails and eaten in the actual work For example, in 1979, when we sampled the surface of Baode Overpass bauxite mining area, we did noticed that weathered grooves were sampled in more than 200 samples, which resulted in the content of SiO_2 in the sample being more than the actual (Samples on fresh side) were 0.74-2.1% higher and 4.28-5.41% lower than that of Fe 2 O 3, which resulted in the scrap of all the samples, which not only caused economic loss but also affected the evaluation progress of the mining area 400 × 400 m spacing drilling, see mine
