Abstract：Maintaining the stability of surrounding rock during filling mining is an important guarantee for coal mine safety production.In order to explore the supporting strength of surrounding rock in paste filling working face,taking the actual situation of the upper lay-ered paste filling working face in Gaohe Energy E1302 as an example,the surface displacement of mining roadway during filling mining was studied and analyzed by using theoretical analysis and field measurement,and finally the supporting strength value required for ef-fectively stabilizing surrounding rock in paste filling working face was obtained,which can provide a basis for supporting design and re-search of similar filling mining projects in the future.
