摘　　要：为了便于掌握王家岭煤矿2号煤层的瓦斯地质规律,采用主成分分析法,对影响2号煤层瓦斯赋存规律的主控因素进行分析和评价,明确影响煤层瓦斯赋存的主控因素,同时结合数量化理论,将定性变量与瓦斯含量相结合,对影响2号煤层瓦斯赋存规律的主控因素进行分析和量化。对其中的定性指标进行归一化处理,确定合理的权重因子,建立表征2号煤层瓦斯赋存规律的数学模型,揭示了2号煤层瓦斯赋存规律。预测结果与实际现场测定数据相差不大,有助于指导现场实际生产。In order to grasp the geological law of the No.2 coal seam in Wangjialing Mine,the principal component analysis method was used to analyze and evaluate the main control factors affecting the gas occurrence law of the No.2 coal seam,and the main control factors affecting the gas occurrence in the coal seam were clarified.According to quantitative theory,and combining the qualitative variables with the gas content,the main control factors affecting the gas occurrence law of the No.2 coal seam were analyzed and quantified,in which the qualitative indexes were normalized,reasonable weighting factors were determined,and a mathematical model was built to characterize the No.2 coal seam gas occurrence law.The prediction results are not much different from the actual field data,which can help to guide the actual field production.
