As there are many influencing factors in grading assessment of top coal cavability,the moment estimation theory which can comprehensively take into account both subjective and objective factors of weighting is used to optimize the weight of each influencing index in the assessment of top coal cavability.This method remedies subjective shortcoming of other evaluation methods.Taking Handan Tao No.2 coalmine as an example, top coal cavability model was established by combining the moment estimation theory and TOPSIS evaluation.The model is applied to 10 groups top coal cavability evaluation.The results show that results of this model are consistent with others as well as actual situation.It is reliable and practical which could offer an important theoretical basis for top coal caving mining.
