摘要
利用崇信县气象观测资料,选用华煤集团新柏煤矿瓦斯浓度观测资料,进行多因子分析,探讨气象条件与矿井瓦斯浓度的关系,选取相关系数绝对值大于0.3的因子,用统计学方法中的逐步回归法进行煤矿区不同回风巷瓦斯浓度预测,建立瓦斯气象条件预警模型,并建立瓦斯气象自动监控预警系统平台,为研究煤矿瓦斯爆炸,减少煤矿安全生产事故的发生,提供科学依据。
Based on the observed meteorological data in Chongxin County and the gas density observed data in Xinbai coal-mine of Huating Coal-mine Company, the relationship between the meteorological conditions and the gas density was analyzed by multi-factors method. The predicted factors with the absolute correlative coefficient more than 0.3 were selected by using stepwise regression method, and the gas density of different channels in coal-mine area was predicted by statistical methods, The prediction model of the gas meteorological condition was established by the stepwise regression. The automatic monitoring warning platform of the gas meteorology was established at the same time. This study provided references of meteorological factors for studying the explosion of coal mine gas and reducing the occurrence of the safety production accidents in coal mines.
