【摘要】：为解决高原矿井掘进面通风难题,以西藏自治区某多金属矿为工程背景,依据层次分析法(AHP)与逼近理想解排序法(TOPSIS),建立通风评判模型,对3种拟定的混合式掘进通风方式进行优选。根据高原矿井负压低氧的特殊环境,从技术、经济、安全3个方面选取通风系统的评判指标,运用AHP法客观确定各评判指标的权重向量,结合TOPSIS法分析贴近度并计算得出各通风方式的综合优越度。计算结果表明,第2种通风方式(长压短抽)优越度最高。通过AHP-TOPSIS优选的结果科学合理且符合生产实际,可为高原矿井掘进通风方式选择提供理论依据。
[Abstract]:In order to solve the problem of mine heading face ventilation plateau, a multi metal mine in Tibet autonomous region as the engineering background, based on the analytic hierarchy process (AHP) and TOPSIS method (TOPSIS), the establishment of ventilation evaluation model to optimize the proposed 3 hybrid driving ventilation mode. According to the special environment, the pressure of the plateau hypoxia from technology, economy, the selected evaluation indexes of ventilation system in 3 aspects of security, using the AHP method to objectively determine the weights of each evaluation index, combined with TOPSIS analysis method and calculated the similarity of ventilation synthetic superior degrees. The results show that second kinds of ventilation (long stub pumping) superior to the highest degree the results of optimization by AHP-TOPSIS. A scientific and reasonable production practice, can provide theoretical basis for the selection of mine ventilation for plateau.
