Abstract

Abstract: Concerning the evaluation of the safety aspect related to gas presence in the coal mine，based on the hazard theory，the main factor contributing to gas incidents is analyzed and then an average index system is created through multi-level inconsistencies decomposing.By incorporating the catastrophe theory together with fuzzy mathematical theory result in the development of the mathematic model，recursion operation is found with the unitary formula as well as the assessed value is obtained.By combining the actual data from the mine field as well as the statistics simulated in the Matlab，in contrast the actual situation shows that the mutation series method has a higher success rate and the objectivity is strong.The new idea is provided for assessing gas risk management.

摘要： 对于矿内瓦斯安全状态的评价，根据危险源理论，分析瓦斯事故的主要因素并进行多层次矛盾分解建立评价指标体系；利用突变理论结合模糊数学建立数学模型，求出总突变隶属函数，得到评价值。结合矿井内实际数据，在MATLAB环境中仿真出结果曲线，对比实际情况表明突变级数法成功率高、客观性强，为瓦斯风险评价提供一条新的思路。
