煤层底板注浆影响因素的灰色关联分析研究

Grey Relational Analysis Research on Influencing Factors of Grouting in Coal Floor

煤层底板注浆改造是有效治理煤层底板水害的有效手段之一。以陈四楼煤矿2517工作面底板注浆改造为研究对象,运用灰色关联分析方法定量分析煤层底板注浆影响因素,根据分析样本得出影响因素与注浆量之间的灰色关联度,并对其进行关联排序。

Grouting transform in the coal floor is an effective method which can be used to control the water hazard from the coal floor. Influencing factors have been quantitatively studied with grey relational analysis about grouting in the coal floor taking the 2517 work face of Chensilou coal mine as an example.The result is that grey relational grades of the influencing factors were achieved by grey relational analysis and compared in the sample.
