The invention discloses a non-explosive mechanical rock breaking room-and-pillar mining method for a gently inclined ore body, which is characterized in that stopes are arranged perpendicular to the trend of the ore body, a stud is reserved between the stopes, the stopes are divided into chambers and continuous strip columns, only the chambers are mined, the continuous strip columns are not mined temporarily, and when the chambers are mined, a cantilever type heading machine enters a heading machine posture adjusting chamber from a connection way; a machine body is rotated and adjusted, the machine body is tunneled upwards along the center line of the chamber to form an air return uphill and is communicated with the upper middle section of the transportation roadway, the cantilever type heading machine backs back to the heading machine posture adjusting chamber, and then ore breaking is conducted along the inclined full section of the chamber to the boundary of the stope; and then the cantilever type heading
