摘要
在系统收集及分析矿区水文地质资料的基础上,确定影响煤层底板突水的主要因素,并引入主成分分析法对影响底板突水的因素进行定量评价。以新安煤矿为例,利用主成分分析法,确定各突水影响因素的权重,建立煤层底板突水模型,对影响煤层开采的底板奥灰突水危险性进行分区预测,为奥灰水的防治提供了重要依据。
This paper analyzed main factors influencing floor water-burst on the basis of analyzing hydrogeology data. Principal components analysis was applied to evaluating these influence factors. Taking Xin＇ an Colliery as an example, weight of every influence factor of water-burst was obtained by principal components analysis and a floor water-burst model was set up. Floor Ordovician water-burst danger was predicted bY areas, which provided important reference for Ordovician water prevention.
