摘要
深部煤层开采底板突水是一个复杂的非线性系统,各影响因素相互关联、彼此耦合。建立了深部煤层开采底板突水的层次分析结构模型,运用专家打分法构建出各层次的判断矩阵,并利用根法层次分析求得影响因素的贡献权重。通过权重分析得到深部煤层开采底板突水的13个控制因素和5个主控因素,研究结果基本符合现场实践。专家打分-层次分析法能够将客观实际升华为主观认知,是一种由定性问题向定量问题转化的方法,可以比较客观、准确地研究包含多因素的"灰箱"问题。
Floor water bursting in deep coal seam mining is a complicate nolinear system, and various influencing factors are coupling and influencing themselves. The paper builds the analytic hierachy structure model for floor water bursting in deep coal seam mining, then the judgment matrix is found by the expert scoring method, the contribution weights of the influenced factors are given by the equa- tion analytic hierachy process. Thirteen controlling factors and five main controlling factors are put award by analyzing weights, so the result is basically conform to the field practice. The expert scoring method and analytic hierachy process can convert the objective fact to the subjective cognition, so it is a method that can turn the qualitative into the quantitative. This can be relative objective and correct to study the question of many factors and grey box.
