煤层瓦斯含量的预测及其影响因素的分析

由于煤层中瓦斯的含量是防治煤矿瓦斯的一项重要指标,以常村矿3#煤层钻孔的统计数据为基础,对这些数据进行统计线性回归并利用瓦斯地质因素分析的方法,找到了影响煤层瓦斯含量的主要因素,运用丰富的钻孔数据和量化的方法,并用多元线性回归建立了可以预测煤层瓦斯含量模型,这种预测可以为矿井瓦斯防治提供一定的依据,以此达到对矿井瓦斯的含量及其分布规律进行有效预测的目的。

Analysis of Influencing Factors and Forecasting of Gas Content in Coal Bed

Coal bed content is the important parameter of methane prevention,it provides technical basis for the methane drainage and gas outburst prevention through predicting coal bed content.Based on drill holes coal uncovering information of Changcun's number three coal bed,this paper found the controlling factors of the impacting coal bed gas by using the methods of gas geological factors analysis and linear statistic discipline.Then quantify the qualitative factors,use multiple linear regression method to build predictive models of gas content through the rich drilling data,achieve the purpose of predicting the gas content and distribution of mine.
