煤矿井下瓦斯爆炸与井上天气变化的有密切关系,煤矿瓦斯爆炸是煤矿生产中的恶性事故,它不仅严重影响着煤炭工业的正常生产,更造成巨大的生命财产损失。文章从山西省主要矿区重大典型事故案例资中分析了煤矿瓦斯的主要气象诱因,建立井下在自然通风情况下瓦斯浓度变化与气象因子的实时监测与预报模型,搭建山西省煤矿瓦斯气象预报预警平台。由此可提前预报煤矿瓦斯浓度变化趋势,提醒煤矿管理人员及时加大通风,搞好煤矿安全生产管理,减轻事故发生,成为气象为能源安全发展服务一种新模式。
Coal mine gas explosion is closely related with the uphole weather changes. Coal mine gas explosion is a serious accident in coal mine production. It not only seriously affects the normal production of coal industry, but also causes huge loss of life and property. In this paper, the main meteorological factors of coal mine gas are analyzed from the major typical accident cases in major mining areas in Shanxi Province. A real - time monitoring and forecasting model of gas concentration change and meteorological factors under natural ventilation is established, and a methane weather forecast and warning platform for coal mine in Shanxi Province is set up. This can be predicted in advance changes in gas concentration in coal mines to remind coal mine managers to increase ventilation in a timely manner, improve coal mine safety management, reduce accidents and become meteorological services for the development of a new energy security model.
