煤层综采受小断层影响程度模糊综合评判

Fuzzy Comprehensive Judgment on Influence Degree of Small Fault to Seam for Fully Mechanized coal Mining

构建了煤层综采受小断层影响模糊综合评判模型,分述了建模时评价指标体系的建立、权重的计算及隶属度的确定等步骤,并以新汶煤矿41108工作面和龙固矿1301N工作面资料为例,分析了断层的走向、倾向、倾角、落差四个影响因子,对研究区进行了综合评判,发现模糊综合评判在对于煤层综采受小断层影响程度的预测方面,有较为科学、合理及准确的评价结果,为回采工作面的正常开采提供了有力保障,在该领域有较为广阔的应用前景。

The fuzzy comprehensive evaluation model of the influence of small faults on fully mechanized mining was established. When the model is founded , the construction of evaluation index system, the calculation of weights and the determination of membership degree were discussed respectively, in addition, taking the 41108 working face from Xinwen coalmine and 1301N working face from Longgu coalmine, analyzed four impact factors including strike, tendency, dip and drop with the comprehensive evaluation on the research area, and found that this method can have more scientific, reasonable and accurate evaluation results, it also produce powerful safeguard for the normal mining of stope on the prediction of the influence degree of fully mechanized mining from small faults, in the meanwhile, it has more broad application prospect on this area.
