前震旦系变质岩系中的鞍山式铁矿,多呈巨大的厚层板状体,层位稳定,构造简单.勘探这类矿床,往往使人感到比较有把握.我队于七一年勘探的某铁矿,矿体地表出露厚度一百多米.已有的三个矿体中,二号和三号矿体的露头为两个矗立的山峯.为了控制矿体的延深,我们参照前人资料,在矿区设计了21个钻孔,工程量五千多米.可是,八号和十二号头两个钻孔一施工就落空了(图1),使地质工作一度处于被动的局面.伟大领袖毛主席指出:“人们要想得到工作的胜利即得到预想的结果,一定要使自己的思想合于客观外界的规律性,如果不
The Anshan-type iron ores in the former Sinian metamorphic series are mostly thick, thick plate-shaped bodies with stable layers and simple structures, and exploration of these deposits often makes people feel more confident. Of an iron ore, ore body surface exposed thickness of more than 100 meters .Ordinary three ore body, the ore bodies of the two outcrops for the two peaks .In order to control the depth of the ore body, we According to the data of predecessors, 21 bored holes were designed in the mining area with a work volume of more than 5000 meters, however, the first two boreholes on the 8th and the 12th failed to complete the construction (Figure 1) The great leader Chairman Mao pointed out: ”If people want to get the victory of their work, that is, the expected result, they must conform their own thinking to the regularity of the objective outside world and if not
