地浸采矿模糊综合评判方法在铀矿开采中的应用

Application of in-situ leaching mining fuzzy comprehensive evaluation method on uranium mining

地浸采矿影响因素众多,具有层次性和模糊性的特点。为了分析砂岩型铀矿床地浸开采的可行性,采用层次分析法和模糊数学理论建立了地浸采矿二级模糊综合评判方法,并运用层次分析法客观地确定各因素的权重,最终建立了基于AHP理论的模糊综合评判方法。研究结果表明:基于AHP理论的模糊综合评判方法可以很好的评判砂岩型铀矿床地浸采矿可行性,既能反应工程实际,又避免了专家在判断各种影响因素相对重要程度时具有随机性。

Many factors which have hierarchy and fuzzy characteristics can affect in-situ leaching mining. In order to analyze the feasibility of in-situ leaching in uranium deposits with sandstone type, a secondary fuzzy comprehensive evaluation methods was built based on analytic hierarchy process and fuzzy mathematics theory,in order to analyze the feasibility of in-situ leaching in uranium deposits with sandstone type. The secondary fuzzy comprehensive evaluation method was built based on analytic hierarchy process and fuzzy mathematics theory, finally established the theory of fuzzy comprehensive evaluation method based on AHP. The results show that the fuzzy comprehensive evaluation method based on AHP can be effectively applied in the feasibility of in-situ leaching in uranium deposits with sandstone type,which not only reflects the engineering reality, but also avoids the randomness produced by experts in judgment of the relative important degree of influencing factors.
