煤层大巷技术可行性多级多因素模糊变权综合评价模型

The fuzzy comprehensive evaluation model of technical feasibility on laying coal main road with multi-factor and variable weights

研究了影响煤层大巷布置的 3个方面、9个影响因素 ,建立了煤层平整性、断层构造适应性、围岩稳定性、围岩膨胀适应性、瓦斯涌出量安全性、瓦斯突出危险性、自燃危险性、冲击地压危险性及可维护性等单因素影响煤层巷道布置的模糊制约关系 ,根据各因素影响的重要性程度的动态变化特点 ,提出了多级多因素模糊变权综合评价模型 .以济宁 3号煤矿为实例进行了验证计算 。

The influence of three aspects and nine factors on laying coal main road is studied. The fuzzy restricted relationships between coal main road and single factor, as coal seam smoothness, fault, rock stability, rock bulge, gas effusion, coal and gas outburst, spontaneous combustion danger, pressure bump, and maintenance, are set up. According to the dynamic variable characteristic of each factors importance, the fuzzy comprehensive evaluation model of technical feasibility on laying coal main road is put forward with multi step, multi factor and variable weights, which is a scientific means of evaluating technical feasibility on laying coal main road. The models computing result in Jining Mine No. 3, as example, agrees with practice.
