砂岩含水层注浆效果评价方法研究

Study on Evaluation Method of Grouting Effect in Sandstone Aquifer

在煤矿防治水工程中,经常会采用注浆的方式实施防治水工程,注浆效果的评价可分为理论分析以及实践检验两个方面。当工程缺少实际检验效果,则理论分析则显得必不可少。以侏罗系直罗组砂岩层注浆效果评价为对象,通过对决定注浆效果的注浆工艺、注浆参数、注浆量以及注浆后检测四个方面进行分析研究,采用模糊数学法将模糊性概念模型化,建立总评价目标,采用数据量化处理的方式对事物的影响因素进行多层次对比分析,最终将多因素影响的定性评价以量化的形式形成最终总目标评价结果,从而达到评价注浆效果的目的。

Grouting is often used in water prevention and control engineering of coal mine.The evaluation of grouting effect can be divided into theoretical analysis and practical test.If the project lacks practical test,the theoretical analysis appears essential.In this paper,the evaluation of grouting effect of Zhiluo Formation Sandstone in Jurassic system is taken as the object,four aspects which determine the grouting effect including grouting technology,grouting parameters,grouting quantity and post-grouting detection,were analyzed.It was using fuzzy mathematics to model the fuzzy conception,and set up the target of overall evaluation.The method of data quantitative processing was used to carry out multi-level comparative analysis of the above factors.Finally,the qualitative evaluations of multi-factors were quantified to achieve the final evaluation resultsand,thus,the final goal of evaluating grouting effect.
