推进矿山绿色开采是一项长期而复杂的系统工程，而绿色开采技术的应用面临着投资周期长和成本高等问题，鉴于此，开展绿色开采技术优先级评价，有助于指导矿山决策部门的工作，实现绿色开采有序化，降低投资成本。在构建三山岛金矿绿色开采技术体系的基础上，提出了一种灰色关联分析优化模型，并利用该模型对绿色开采技术进行评价分析。首先，构建了层次化绿色开采技术评价指标体系，系统地反映了各因素对绿色开采技术的影响；然后，利用AHP法和熵值法组合赋权，弥补了主观赋权法和客观赋权法的不足，使赋权趋于合理化；最后，分别应用3种赋权方法的优化模型和传统等权法模型对三山岛金矿绿色开采技术的绿色度进行量化分析，并对比分析了4种模型的关联度计算结果，最终得出三山岛金矿绿色开采技术推进的优先级。

The exploitation of mineral resources is accompanied by the destruction of ecological environment.For a long time，based on the idea of green mining industry，many scholars have conducted researches on green mine and green mining，therefore，a large number of technical materials and evaluation data are accumulated.In order to achieve the goal of high-efficiency，waste-free，harmless and ecological mining，Sanshandao gold mine has been continuously exploring and promoting green mining，and a series of green mining technologies have been innovated and excavated.However，there are no precedents and theoretical guidance in the early application of relevant technologies，and the investment problems of long cycle and high cost are faced，so it is particularly necessary to carry out the priority analysis of technology application.Based on the geological conditions of the mining area and the existing technological innovation achievements，the green mining technology system of Sanshandao gold mine was established，which is mainly composed of four key technologies and eight innovative technologies.On this basis，an optimized model of grey correlation analysis was put forward to evaluate and analyze green mining technology.Firstly，a hierarchical evaluation index system of green mining technology of target layer，criterion layer and index layer was constructed to systematically reflect the influence of various factors on green mining technology，and eight innovative technologies of Sanshandao gold mine were selected as evaluation objects.Then the combination weighting of AHP and entropy weight method was used to make up for the deficiency of subjective and objective weighting method，which makes the process of weighting tends to be reasonable.Finally the green degree of Sanshandao green mining technology was quantitatively analyzed by using the optimized model of three weighting methods and the traditional equal-weighting model，by comparing and analyzing the results of correlation degree of four models and ranking eight green mining technologies，the priority of green mining technologies of sanshandao gold mine was obtained.The results show that，among the evaluation indexes，the weight of personnel operation safety，mechanical and intelligent degree and the level of resource recovery and utilization is relatively large to green mining technologies.Among the technologies，the application of trackless intelligent equipment has the highest priority and contributes the most to the goal of green mining.This result indicates that the direction of technological innovation of Sanshandao gold mine should focus on realizing mechanical and intelligent mining.This result is helpful in guiding the work of decision-making department，realizing the ordering of green mining and reduce the cost of investmentt in Sanshandao gold mine.
