摘要
为确定采区最优的区段煤柱宽度,在建立区段煤柱宽度综合决策指标系统的基础上,综合运用层次分析法(AHP)、熵权法、加权灰色关联分析法(GRA)和加权TOPSIS法基本原理构建区段煤柱宽度综合决策体系,对多种区段煤柱宽度方案进行综合决策优选。优选过程中,通过AHP和熵权法组合赋权获得各决策指标的权重向量,再结合灰色关联分析法(GRA)和逼近理想解的排序法(TOPSIS)法各自优点,建立综合决策模型对拟选方案进行定量分析,并对区段煤柱宽度设计方案进行综合决策排序。以冯家塔煤矿区段煤柱宽度方案优选为例,得出7种拟选方案的相对贴合度分别为52.88%,58.99%,36.39%,31.96%,42.13%,42.15%和52.81%,最终确定第2种方案最优即煤柱宽度为11 m最佳。经现场实践验证,表明该综合决策体系具有相当的可行性和有效性,为区段煤柱宽度的确定提供了一种新的计算思路。
In order to determine the optimal sectional coal pillar width in the mining area,on the basis of establishing the comprehensive decision-making index system for the width of the coal pillar in the section,the basic principles of the analytic hierarchy process(AHP),the entropy method,the weighted gray correlation analysis(GRA)and the weighted TOPSIS method are used to construct a comprehensive decision-making system for the width of the sectional coal pillar,and the comprehensive decision-making scheme of multiple sections of the coal pillar width is optimized.In the process of optimization,the weight vectors of each decision-making index are obtained by combining AHP and entropy weight methods,and combined with the advantages of grey correlation analysis method(GRA)and the ranking method(TOPSIS)method of approximation ideal solution,a comprehensive decision-making model is established to quantitatively analyze the proposed selection scheme,and the comprehensive decision-making ranking of the sectional coal pillar width design scheme is carried out.Taking the preferred coal pillar width scheme in the Fengjiata Coal Mine section as an example,the relative fit of the seven proposed schemes is 52.88%,58.99%,36.39%,31.96%,42.13%,42.15%and 52.81%,respectively,and the optimal scheme is determined,that is the second scheme,in which the coal pillar width is 11 m.According to the on-site practice verification,it shows that the comprehensive decision-making system has considerable feasibility and effectiveness,and provides a new calculation method for determining the width of the coal pillar in the section.
