备注

鉴于许疃矿32块段3222切眼持续突水,为了快速有效地判别出该矿出水点的水源类型,为该矿防治水措施的制定提供科学依据,通过利用所收集的许疃矿32块段不同含水层常规水化学数据和与其具有相同水质单元的任楼矿部分水化学数据,依据各含水层地下水化学组分情况,最终选取了7种能够区分各含水层类型的水化学指标,并借助SPSS软件建立了许疃矿突水水源的Fisher识别模型。训练水样的判别结果经回估后发现,该模型在许疃矿水源类型的判别中正确率高,表明此模型在许疃矿水源判别中效率较好,可作为许疃矿矿井突水时快速判别水源类型的一种依据,对该煤矿日后安全生产具有一定的实际意义。最后对许疃矿出水点待判水样进行科学判别,判别结果为:所有待判水样均为砂岩水。另外,论文中许疃矿水源判别模型建立时未考虑各含水层混合后的情况,因此该模型还可作进一步研究。

In view of continuous water inrush of 3222 cut in Xutuan mine block 32,in order to discriminate the water source style for watered point quickly and effectively in the mine,and to provide scientific basis for making measures to prevent and control water,through using conventional hydrochemistry data in diffirent aquifers collected from Xutuan mine block 32 and some hydrochemistry data from Renlou mine which has sane water quality compared to Xutuan mine,according to hydrochemical component in each aquifer,choose seven hydrochemical indexes that can distinguish every aquifer style finally,and in virtue of SPSS software to establish the water inrush Fisher discrimination model for Xutuan mine.The evaluation results after discriminating the training samples indicate the accuracy of discriminanting water source style in Xutuan mine about this model is high with good efficiency,which can be used as a basis to discriminate the water source style on water inrush in Xutuan mine,and it has a certain practical significance to the safety production of the coal mine.Finally,discriminating unknown water source for watered point in Xutuan mine scientifically,the result demonstrates they are all sandstone water.In addition,the water source discriminantion model of Xutuan mine is established without considering the conditions of mixed aquifers,so this model can be further studied.
