综采顶板砂岩富水性多元信息预测评价

Forecasting and assessment of water abundance of sandstone roof by multivariate information

为预防矿井顶板水害的发生,针对现有方法对顶板砂岩富水性预测存在的问题,着重研究了多因素对富水性的影响,并提出了富水性综合分析预测评价方法。在指标选取上更注重科学性和实用性,最大程度的利用了资源勘探孔的资料进行富水性预测。并以济宁二号井为实例,进行应用验证,为煤矿顶板含水层富水性预测评价提供了一种新方法。

In view of the mine roof problem in the process of occurrence and prevention and control of water disasters,as well as the existing method to predict the roof sandstone water problems, this paper studies themulti-factor comprehensive analysis on the influence of water content, we pay more attention to scientific andpractical index selection.It can make the best use of the exploration hole data. And verification was conductd inJining No. 2 well. It provides a new method for water prediction in coal mine roof aquifer.
