基于未确知测度的煤矿瓦斯爆炸应急救援能力综合评估

Comprehensive evaluation of mine gas explosion emergency rescue capability based on unascertained measure

为解决我国煤矿瓦斯爆炸应急救援能力评估中主观性与模糊性的问题,首先选取煤矿通风系统管理、煤矿防瓦斯积聚能力、应急救援技术保障、应急救援组织保障、应急救援装备保障、煤矿救援恢复能力等6方面共29项判别指标构建煤矿瓦斯爆炸应急救援能力评估指标体系;其次,引入未确知测度与博弈论集对理论构建煤矿瓦斯爆炸应急救援能力等级评估与排序模型,采用直线法构造单指标未确知测度函数,基于博弈论组合赋权技术确定指标权重,依据置信度识别准则对评价等级进行判定与排序;最后,将该模型应用于高瓦斯煤矿的应急救援能力的综合评价中。研究结果表明,该煤矿的瓦斯爆炸应急救援能力评估等级为良好,但仍需要进一步采取有效的管控措施,该模型具有较高的适用性与可操作性,能够较为客观、准确地评价煤矿瓦斯爆炸应急救援能力。

In order to solve the problems of subjectivity and fuzziness in the evaluation of mine gas explosion emergency rescue capability in China, firstly, a total of 29 discriminant indexes were selected from 6 aspects, including mine ventilation system management, mine gas accumulation prevention ability, emergency rescue technical support, emergency rescue organization support, emergency rescue equipment support, and mine rescue and recovery ability to construct the evaluation index system of mine gas explosion emergency rescue ability. Secondly, the unascertained measure theory and game theory set pair theory were introduced to construct the mine gas explosion emergency rescue capability level evaluation and sorting model, the straight-line method was used to build the unascertained measure single index function, the index weight was determined based on game theory combined weighting, and the order of evaluation level was decided according to the degree of confidence recognition criteria;finally, the model was applied to the comprehensive evaluation of the emergency rescue capability of a high gas coal mine. The results show that the evaluation level of the coal mine’s emergency rescue capability is good, while further effective control measures are still needed. The model has high applicability and operability, and which can objectively and accurately evaluate the comprehensive evaluation of the coal mine’s emergency rescue capability of gas explosion.
