基于AHP-Fuzzy法的煤矿立井冻结法施工风险管理研究

为了减少煤矿立井冻结施工中的安全事故,通过对立井冻结实际工程案例的分析总结,采用层析分析法对各风险因素的评价指标进行权重计算,并结合模糊评价法建立风险因素综合评价矩阵,最终依据最大隶属度原则得出立井冻结法施工中存在的高风险指标及一般风险指标,在此基础上,从组织、技术、经济等方面制定出对应的风险预控措施,从而有效控制煤矿立井冻结法施工风险。

Research on Construction Risk Management of Mine Shaft Freezing Method Based on AHP-Fuzzy

In order to reduce safety accidents in shaft freezing construction of coal mine, taking the coal mine shaft freezing construction project as an example, according to the datas of analysis and summary of the implementation of the project, the weights of each evaluation index of construction risk factors is determined by AHP method, and the fuzzy evaluation method is used to establish a comprehensive evaluation matrix of risk factors. According to the principle of maximum membership degree, the high-risk indicators and general risk indicators in the construction of the shaft freezing method are determined. Based on analyzing results, the risk pre-control measures are formulated from the aspects of organization, technology and economy to effectively control the construction risk of the mine shaft freezing method.
