摘要
煤矿采空区稳定性评价是一个受众多因素影响的复杂问题。根据平煤六矿一采空区的实际资料,优选出11个主要影响因素,针对这些因素之间的相互作用关系,建立采空区稳定性评价指标体系。运用多级模糊数学方法建立起二级综合评价模型,采用层次分析法确定各影响因素的权重,并对该采空区的稳定性进行了评价,得到了与实际较为一致的结果,为采空区治理提供了参考和依据。
On the basis of practical datas of a mined-out area in No.6 Pingdingshan coal mine,11 main factors were analyzed.Due to the interaction among these factors,mined-out area stability evaluation index system was established.Two-level comprehensive evaluation model was set up by using multi-level fuzzy mathematics method,and weights of each factors were confirmed with analytic hierarchy process.The stability of this mined-out area was evaluated,and the results were close to the reality.It provides reference and basis for mined-out area control.
