| 摘 要： | 煤矿瓦斯爆炸是当前对煤矿安全生产威胁最大、最突出的问题之一.对瓦斯爆炸开展危险源辨识和评价,必须全面考虑评价对象指标.文中在3类危险源划分理论的基础上对其划分进行修正,进而构建初步的瓦斯爆炸3类危险源评价指标体系.该体系包括3类共33项；通过现场数据收集,基于粗糙集方法将该指标体系数据约简为19项；采用Rosetta软件进行仿真计算,借助神经网络工具,通过煤矿瓦斯危险源评价过程来验证指标约简的合理性.经验证得出,粗糙集处理后的危险源评价神经网络在模拟计算过程中精度大幅度提高,网络收敛速度加快,证明了应用粗糙集方法对煤矿瓦斯爆炸危险源评价指标体系进行优化是可行的.开展煤矿瓦斯爆炸危险源评价指标体系的优化研究,对于提高危险源评价系统的准确性和实时性具有一定的积极意义. |

| Abstract: | Comprehensive targets of safety evaluation should be taken into account to identify and assess gas explosion accidents.This paper revised the division of three types of hazard in coalmine based on the Three Type Hazard theory,and set up a preliminary evaluation index system of gas explosion,including three types 33 terms.Data on spot was collected,and the index were reduced to 19 terms based on Rough Set.Software Rosetta was used for simulation through gas hazard evaluation to test the reduction was reasona... |
