煤矿底板突水的众多因素中,各因素影响大小不同,利用模糊数学综合评价和统计中的单因素方差法对厚煤层底板突水危险性进行权重的评价,对于预防和预测底板突水灾害的发生具有重要的理论指导意义和实用价值。根据影响底板突水的众多因素的非线性关系的复杂特征,在模糊数学评价法的基础上加入权重指标的判断依据,保证评价的较高精度,为研究煤层底板突水的评价提供理论依据。
Among the many factors of water inrush in coal mine floor, the influences of different factors are different, and the weight of water inrush from thick seam is evaluated by fuzzy comprehensive evaluation and single factor variance method in statistics. Occurrence has important theoretical significance and practical value. According to the complex characteristics of the nonlinear relationship of many factors that affect the water inrush of the floor, the judgment basis of the weight index is added based on the fuzzy mathematics evaluation method to ensure the higher accuracy of the evaluation, which provides a theoretical basis for the research on the evaluation of water inrush from coal seam floor.
