为了对不同水害类型的矿井进行分类以制定相应的防治水措施,选取矿井涌水量、突水量以及主要含水层单位涌水量作为聚类指标,基于MATLAB的模糊聚类分析法将研究的11个矿井进行分类。结合水文地质条件可将矿井分为4类,第1类矿井主要水害为地表水、烧变岩水和风氧化带水,防治措施为留设防隔水煤(岩)柱;第2类矿井主要水害为顶板水,要采取超前探查和预疏放;第3类矿井主要水害为构造充水,需要精细探查井田内的构造;第4类矿井主要水害为顶板水,且矿井涌水量较大,建议开展顶板含水层富水性探查。结果表明:基于MATLAB的模糊聚类分析法不仅符合矿井水害复杂和模糊的特性,并且准确快速。

In order to classify the mine with different types of water disaster and make corresponding measures for water prevention and control, mine inflow value, water inrush value and unit inflow value of the main aquifer were selected to be clustering index.The fuzzy clustering analysis method based on MATLAB was applied.C ombined with hydrogeology condition analysis of 11 mines, the optimal classification number is 4.The first kind of min water disaster were surface water, burnt rock wat er and wind oxidized zone water, prevention and control measure was keep the coal (rock) pillars.The second was coal roof water, advanced detection and preliminary drained should be taken.The third was structural water, probing structure should be needed.The last was coal roof water and mine inflow was large .Probing water abun dance of aquifer on coal roof was suggested.The results showed that the fuzzy clustering analysis method based on Matlab not only conform to complex and fuzzy char acteristics of the mine water disaster, but also has the characteristics of quickly and accurate.
