Fuzzy Clustering Analysis and Application of the Degree of Difficulty of Coal Seam Water Injection

Abstract:

The degree of difficulty of coal seam water infusion is the important basis of pouring water into coal beds, by fully analyzing influence factors of the degree of difficulty of pouring water into coal beds, the main influence factors of pouring water into coal beds was determined and the fuzzy clustering analysis model was build which base on the depth of burying of the coal seam, crack growth degree, porosity, moist edge, water saturation value-added and consistent coefficient. By comparing evaluation result of this model with Fisher evaluation result, the model result is accuracy and reliability. According to this model to predict South decurrent 18th layer 7th face Coal Seam of Shuangyashan Mining Group Dongrong No.2 Coal Mine,the predicted results are consistent with the actual situation and offering theoretical guidance to the choice of injection water parameters .
