基于模糊层次分析法的高原矿井人机功效评价

高原矿井人机功效评价是关系到高原高效采矿的重要问题之一，高原地区施工相比平原地区更加复杂。从人员因素、设备因素和环境因素3个方面出发，确立了17个评价指标，以构建高原矿井人机功效评价指标体系。同时，采用层次分析法计算各项指标的权重，并在此基础上建立多层次模糊综合评价模型。以西藏某铜多金属矿为研究对象，构造判断矩阵，建立权重向量和综合模糊矩阵，得出系统隶属度向量。评价结果表明：该系统的人机功效评价结果为“中等”水平，受环境因素影响严重。该评价模型为制定提高人机功效的合理对策提供了科学依据，具有一定的理论意义与实用价值，也为类似的高原施工问题提供了参考。

Evaluation of Human-Machine Effectiveness of Plateau Mine Based on Fuzzy Analytic Hierarchy Process

The evaluation of human-machine efficiency in plateau mines is one of the important issues related to high-efficiency mining at high-altitude.Compared with the plain area，it is more complex.The mining industry at home and abroad rarely develops the ergonomics of high altitude and cold or special and extremely difficult environments.The high-altitude，low-pressure，low-oxygen，low-temperature environment not only causes a significant reduction in personnel fatigue tolerance，but also negatively affects the ability and efficiency of personnel to operate equipment，and produces correlation feedback with complex production factors such as multiple types of work and continuous labor in mines.It has a superimposed effect on the decline of human-computer efficiency.Taking a copper polymetallic mine in Tibet as the research object，this paper investigated and analyzed the influencing factors of human-machine effectiveness of plateau mines and scores made by experts.From the three aspects of human factors，equipment factors and environmental factors，17 evaluation indicators were established and a comprehensive evaluation index system suitable for high-altitude mines was constructed. The weight of each index was determined by analytic hierarchy process，so as to clarify the weight of each influential factor index in each level and the whole.The multi-level fuzzy comprehensive evaluation method was used to construct the judgment matrix.The weight vector and the integrated fuzzy matrix were established to obtain the system membership vector.The evaluation results of the mine indicate that the ergonomic evaluation level of the mine is “medium”.The analysis of the evaluation results shows that the oxygen pressure in the environmental factors is low，which has a great impact on the physical condition of the employees and the operating state of the equipment.To improve the human-machine efficiency of the mine，the working environment at the construction site should be improved.Based on the analysis of human-machine effectiveness and the characteristics of high-altitude mines，this paper establishes an evaluation index system for human-machine effectiveness of plateau mines.The comprehensive scientific nature of evaluation was fully considered when setting indicators.The evaluation index system was weighted and the evaluation model was constructed.In order to reduce the influence of subjectivity on the evaluation results of human-machince effectiveness in AHP method，the analytic hierarchy process and fuzzy comprehensive evaluation method were combined to evaluate the human-machine effectiveness of plateau mine.The method has the characteristics of rationality，objectivity and scientificity to avoid artificial error.This model can provide an effective tool for the evaluation of the plateau mine management，provide support for the optimization of production organization in high-altitude and high-altitude mines，and provide a scientific basis for formulating reasonable countermeasures to improve human-effects.It has certain theoretical significance and practical value.It provides a certain reference for similar plateau construction problems.
