摘要
为更有效地预防煤矿瓦斯灾害,对煤矿瓦斯危险源风险进行评价至关重要。基于区域灾害系统理论,建立由致灾因子、孕灾环境和受灾体三部分组成的煤矿瓦斯危险源风险综合评价模型。该模型首先通过属性数学方法对致灾因子的危害性进行评价;然后利用模糊综合评价法对孕灾环境的敏感性和受灾体的脆弱性进行评价;最后将评价结果映射到风险立方体模型,实现对煤矿瓦斯危险源风险更完整和更有效的评估。将建立的评价模型应用到山西古城煤矿瓦斯危险源的风险评估,结果表明利用该模型得到的评价结果与实际情况相符,验证了该模型的可行性和有效性。
To effectively prevent coal mine gas disasters,it is necessary to conduct risk assessment of the coal mine gas hazard sources.To this end,this paper proposes a comprehensive risk evaluation model for coal mine gas hazard sources,which consists of three aspects:disaster causing factors,disaster pregnant en-vironment and disaster affected body.This model uses an attribute mathematics method to evaluate the harmfulness of disaster causing factors,and a fuzzy comprehensive evaluation method to evaluate the sensi-tivity of disaster pregnant environment and the vulnerability of disaster affected body,and then maps the evaluation results to the risk cube model to realize a more complete and effective evaluation of the risk of coal mine gas sources.To test the performance of the proposed method,we collect the data of the Gucheng coal mine in Shanxi Province to verify the model.The test results show that the evaluation result by the proposed method is in accordance with the actual result,which demonstrates the feasibility and effective-ness of the proposed method.
