Abstract: Obtaining the thickness value of the cover rock is the key factor of the caving method.In view of the actual situation of the mining in Dahongshan iron mine,The thickness value of cover rock of caving method in Dahongshan iron mine is acquired by adopting the theoretical caculation and numerical simulation method from the perspective of the mining technology of underground mining and mining safety respectively.

Key words: Caving method, Cover rock, Reasonable thickness
