瓦斯爆炸是煤矿生产中的恶性事故,它不仅严重影响煤炭工业的正常生产,更造成巨大的生命财产损失。煤矿井下瓦斯爆炸与井上天气变化关系密切,本文根据山西省晋中市1995~2009年煤矿重特大瓦斯爆炸事故发生时的瓦斯浓度与气象影响因子数据和2009年7月20日到2011年3月10日11个中型煤矿井下逐日、逐小时瓦斯浓度监测资与气象资料,利用统计学的方法,确定了煤矿瓦斯的主要气象诱因为前一日风向风速的变化、前1~2日气温变化和前2日气压变化,建立了煤矿瓦斯浓度与影响因子的关系模型,构建了山西省煤矿瓦斯气象预报预警系统,建立了井下自然通风区瓦斯积聚的预报模式,可提前预报煤矿瓦斯浓度变化趋势,警示煤矿管理人员及时加大通风,搞好预防措施,避免事故发生,创建了气象为煤矿安全服务的新模式。
Gas explosion is a serious accident in coal mine production. It not only seriously affects the normal production of coal industry, but also causes tremendous loss of life and property. According to the data of gas concentration and meteorological factors at the time of occurrence of gas explosion of coal mine in Jinzhong City, Shanxi Province from 1995 to 2009, and the data from July 20, 2009 to March 2011 The daily meteorological monitoring data and meteorological data of 11 medium-sized coal mines at 11 medium-sized coal mines on the 10th were used to determine the main meteorological inducement of coal mine gas from the previous day’s wind speed and wind speed, Established the relation model between the gas concentration and the influencing factors in the coal mine, built the gas and weather forecasting and warning system for the coal mine in Shanxi Province, and established the forecast mode of the gas accumulation in the natural ventilation area downhole, which could predict the changing trend of the coal gas concentration in advance, Warning coal mine managers to increase ventilation in a timely manner, do a good job in preventive measures to prevent accidents, and created a weather meteorological service for coal mine new model.
