摘要
为了系统防治及综合利用云南省煤矿瓦斯,在分析云南省煤炭资源分布及开发现状的基础上,开展了云南区域性煤矿瓦斯事故统计分析及全省煤矿瓦斯区划研究。分析研究表明,云南省煤矿瓦斯事故类型主要有瓦斯爆炸及燃烧、瓦斯窒息和煤与瓦斯突出三大类,随着开采深度不断加大,煤与瓦斯突出事故明显增多;瓦斯事故主要发生在高变质的无烟煤、贫煤、瘦煤和中变质的焦煤中;云南省煤矿瓦斯具有明显的区域分布特征,其区域性规律主要与成煤地区的成煤时代、瓦斯赋存规律、地质构造及其演化、煤矿开采现状等有关。在此基础上,将云南省煤矿瓦斯区划为5个一级单元、9个二级单元。
In order to systematically prevent and comprehensively utilize coal mine gas in Yunnan province,based on the analysis of the distribution and development status of coal resources in Yunnan province,the statistical analysis of regional coal mine gas accidents and the study of coal mine gas zoning in Yunnan province were carried out.The analysis and research showed that the types of coal mine gas accidents in Yunnan province mainly included gas explosion and combustion,gas suffocation and coal and gas outburst.With the increasing mining depth,coal and gas outburst accidents increased significantly;gas accidents mainly occurred in high metamorphic anthracite,meagre coal,lean coal and medium metamorphic coking coal;coal mine gas in Yunnan province had obvious regional distribution characteristics,and its regional law was mainly related to the coal forming age,gas occurrence law,geological structure and its evolution,coal mining status and so on.On this basis,the coal mine gas in Yunnan province was divided into five primary units and nine secondary units.
