摘 要:在进行煤层底板突水脆弱性评价时,往往是通过不同的模型及计算方法得到各个影响因素的常权权重,各个分区均采用此固定常权权重,忽略了不同分区中各个影响因素指标值在不同的组合状态下,其影响权重需随之调整,以反映各影响因素对于煤层底板突水相对重要性的变化问题。本文结合AHP确定的各影响因素常权权重,引入分区变权模型,调整各分区不同因素组合状态下的权重分配,改进了常权权重在不同分区评价中的不合理性,进一步提高了评价结果的精度,对安全开采具有一定的参考价值。The traditional vulnerability assessment of water inrush from coal seam floor often obtains the constant weight of each influence factor through different models and calculation methods.When evaluating,each subarea adopts this fixed weight,ignoring the fact that the index values of each influence factor in different subareas are in different combinations,and the influence weight should be adjusted accordingly to reflect the relative importance of each influence factor in water inrush from coal seam floor in real time.In this paper,combined with the constant weights of the influence factors determined by AHP,the zoning variable weight model is introduced to adjust the weight distribution of different zones under different combinations of factors,which improves the irrationality of constant weights in different zoning evaluation,further improves the accuracy of evaluation results,and provides some reference for the safe production of coal mines.
