根据近十年就地破碎浸铀法的现场试验与理论研究,总结出该法具有堆高超常规性、堆形不规整性、堆场封闭性及隐蔽性,矿石破碎的一次性,矿石破碎块度及其级配的重要性、防止它对井下污染扩散的必要性等技术特点。为了保证成功应用该法必须慎重考虑这些技术特点,并用“非常有利、有利和不利” 作应用准则,做了较全面的量化研究。这项研究结果对合理选择该法的应用条件,减少推广应用中的盲目性具有积极意义。
According to the field experiments and theoretical studies on in-situ crushing impregnation of uranium in the recent ten years, the paper summarizes that the method has the advantages of high heap height, heap irregularity, yard sealing and concealment, one-time ore crushing, Degree and the importance of its grading to prevent it from the proliferation of underground pollution and other technical features. In order to ensure the successful application of the law, we must carefully consider these technical features and make a more comprehensive quantitative study using the “very favorable, favorable and unfavorable” application guidelines. The results of this study have a positive meaning for judging the application conditions of the law and reducing the blindness in popularization and application.
