摘要: 煤层注水难易程度是确定煤层注水方式的重要依据，通过对煤层注水难易程度影响因素的充分分析，确定了影响煤层注水难易程度的主要因素并建立基于煤层的埋藏深度、裂隙发育程度、孔隙率、湿润边角、饱和水分增值和坚固性系数为指标的模糊聚类分析模型。通过对本模型评判结果与Fisher判别分析方法评判结果及煤层注水实际情况进行对照，验证了本模型的可靠性和准确性。依据此模型对双鸭山矿业集团东荣二矿南二下延18层7面工作面煤层进行预测，预测结果与实际情况相吻合。Abstract: The difficulty degree of coal seam water infusion is the important basis of determining coal seam water infusion ways, by fully analyzing influence factors of difficulty degree of coal seam water infusion, the main factors of influencing difficulty degree of coal seam water infusion was determined and the fuzzy clustering analysis model was built based on the burying depth of the coal seam, crack development degree, porosity, moist edge, water saturation value-added and consistent coefficient. By comparing evaluation result of this model with Fisher discrimination result and the actual situation of coal seam water injection, the model result is accuracy and reliability. According to this model to predict South decurrent 18 layer 7 working face coal seam of Shuangyashan Mining Group Dongrong No.2 Coal Mine, the predicted results are consistent with the actual situation.
