摘要
矿井突水是煤矿生产过程中的主要自然灾害,准确判定矿井突水水源是解决突水问题的重要条件。基于模糊综合评判和矩阵方程分析数学原理,分别建立了矿井突水的模糊综合评判和矩阵方程分析模型;在水化学分析的基础上,建立了水样6项指标评判标准,利用两种方法分别对某煤矿3个不同突水巷道水样进行了水源判别,并与实际突水水源相比较。结果表明,模糊综合评判和矩阵方程分析均能有效判别矿井突水水源,但各有其优越性及局限性,选择何种判别方法应视矿井突水水化学资料状况而定。
This paper is inclined to make an hydrochemistry analysis based on the source determination of coalmine water-bursts,which serves as a major natural hazard usually experienced in a typical coal mine. Scientifically speaking,precise location of the bursting water sources is the precondition to treating the problem of water-bursts. In this paper,we have applied the comprehensive fuzzy evaluation method and the matrix equation analysis method to decide the origin of the bursting water in the coal mines. It is just from this need that we have compared the findings gained by using the two methods each with the other. Hence,the paper has made a penetrating examination of the results of our comparison,including the advantages and disadvantages of the two methods in pursuing the sources of the coal mine bursting water. To gain the sound decisive results of the sources of bursting water and personally experience the actual conditions in the typical coal mines,we have strictly explored the principles of the comprehensive fuzzy evaluation and those of the matrix equation analysis. In doing so,we have chosen the following six indicators,such as K＋＋ Na＋,Ca2 ＋,Mg2 ＋,Cl-,SO2-4and HCO-3so as to remove the hydrochemistry effects upon the deterministic results. The three tunnels which experience the water burst should be taken as the subjects of the deterministic analysis,for they are originated from the same coal mine. In this paper,we have established a criterion for deciding the aquifer that was specifically used for the said situations. We have made a hydrochemistry analysis based upon the said analysis by using the same comprehensive fuzzy evaluation model and the matrix equation analysis model. The above said two models have been then used to determine the sources of bursting water in the above mentioned three tunnels. The results were then used to compare to the actual situations. And,finally,we have detected that both the methods,despite their respective strengths and weakness,are capable to be used to make the e
