摘要
金属矿成因复杂,矿体形态大多呈不规则状.由于巷道与巷道之间矿体变化情况不详,常常造成很大的施工浪费的情况.我们借用煤矿开采中探测构造与涌水通道常用的音频电透视方法,在赵案庄铁矿8号矿块巷道上进行了试验探测,克服了常规直流电法受铁轨及直流电场变化干扰的缺点.根据试验探测资料结合地质分析,最终给出了地质探测成果图.矿山开采验证表明,探测成果与实际情况吻合较好,这为金属矿山井下物探测量提供了较好的物探方法.
Because of complicated causes of formation, the shape of metal ore is mostly irregular. Vague distribution of ore body between laneways often result heavy over expenses of exploitation. Following the method commonly used in the detecting of geological structure and water gush in coal mines, we carried out a test exploration of audio-frequency electric perspective in No. 8 laneway of Zhaogezhuang iron-ore mine. Getting rid of the disturbance from the railway in the laneway that troubles DC electric exploration method deadly, the audio-frequency electric perspective gets a good geological exploration result about the distribution of ore body. The practical exploitation check shows that the exploration result is well in accordance with the actual distribution of ore body between laneways. The test offers a good method for the exploration of metal ores in laneways.
