合理地确定矿井水文地质类型,对矿井安全生产、合理防治矿井水害、水资源综合利用,为上级管理机关提供宏观决策和为生产部门指明工作方向有一定的参考价值。根据《规程》(注)中规定的分类依据,我们给出一种应用多级模糊综合评判模型划分矿井水文地质类型的一种方法,该方法可用于采掘矿井的资料整理和待开采矿井类型预测。 一、问题的提出 设B为某待分类矿井,V_k为分类所要考虑的因素集记V_k={v_1,v_2,…,v_n},(k=1,2,…m)。 若从V_k中任何一个因素考虑V_k均属Ⅱ类,而对V_k这m个因素考虑B均属Ⅱ类,则B自然属Ⅱ类,但由于水文地质条件复杂多样,这样情况很少存在,事实上常常是从v_1这个因素考虑V_k属Ⅱ类,从v_j这个因素考虑V_k属Ⅳ类,由于各个因素对V_k和B的影响程度是不同的,所以划分类型对各层次各因素所占比重也是不一样的。另外就其每个因素本身而言,它属于各类别的界限是模糊的,综上所述,B应属于哪类?我们认为这属多层次模糊现象问题,本文力图用多级模糊综合评判解决上述问题。
Reasonably determine the type of mine hydrogeology, mine safety, reasonable prevention and control of mine water damage, comprehensive utilization of water resources for higher-level management agencies to provide macro-decision-making and work for the production department to indicate the direction of a certain reference value. According to the classification basis stipulated in “Regulations” (Note), we present a method for classifying mine hydrogeology using multi-level fuzzy comprehensive evaluation model. This method can be used to mine the data of coal mines and predict the types of mines to be mined . First, the problem raised Let B be a mine to be classified, V_k for the classification of factors to be considered set V_k = {v_1, v_2, ..., v_n}, (k = 1,2, ... m). If V_k is considered as a class II from any factor of V_k and B is considered as class II for these m factors of V_k, then B is naturally a class II, but due to the complex and diverse hydrogeological conditions, such a situation rarely exists. V_k is usually a class II from the factor of v_1, V_k belongs to class Ⅳ from the factor of v_j, because the impact of each factor on V_k and B is different, so the type of each factor is not proportional to the proportion of each level the same. In addition, for each factor itself, it belongs to the boundaries of various categories is vague, in summary, B should belong to what kind? We think this is a multi-level fuzzy phenomenon, this paper tries to use multi-level fuzzy comprehensive evaluation The above problem.
