The invention relates to a method for arranging a support of a top coal caving working face for whole working face coal caving. Two to three meso-position top coal caving transition supports are arranged at the upper end part and the lower end part of the working face respectively, a jack of a coal caving skylight is adjusted by adjusting the meso-position top coal caving transition supports, so that top coal is respectively put on the machine head and the tail of a rear scraper conveyer through the coal caving skylight of the support; a low-position top coal caving support is arranged at themiddle of the working face, through adjusting a tail beam of the low-position top coal caving support, the top coal is put into a middle groove of the rear scraper conveyer through the tail beam of the support. The method for arranging the support of the working face is novel and reasonable in design, simple and easy to operate, practical, high in percentage recovery and low in coal caving cost; the difficult problems of goaf gas and spontaneous combustion in the top coal caving process are solved.
