基于灰色关联分析的矿井突水水源定量化判别方法

Quantify Discriminated Method of Water Source of Mine Water Inrush Based on Grey Relational Analysis

阐述了矿井突水水源的判别方法,针对水化学背景值特征相近的水源,提出了通过量化计算实现精确判别水源层的方法。以灰色关联分析方法为例,对袁店二矿F14断层突水水源进行了量化判别,并采用水化学玫瑰花图和水样柱状图的图形化分析方法对突水水源量化判别的准确性进行了辅助判别,综合分析认为煤层顶板砂岩裂隙水通过断层带进入了采掘空间。定量化地学方法和图形化分析方法有效解决了矿井突水水源判别的准确性。

The discrimination method of water source in mine water inrush was stated, to water resources that with similarly water chemical background, then accurately water source discrimination method was realized according to quantify calculation. It taking grey relational analysis as an example, water inrush source of F14 fault in Yuandian the second mine was discriminated quantify, and auxil- iary method that water chemical rose diagram and diagram analysis method of water sample histogram also were used, sandstone frac- ture water in coal roof entranced into mining space through fault zone. Water source discriminated by qualify chemical method and dia- gram analysis method effectively.
