Based on the traditional room and pillar mining， room and pillar continuous mining machine mining of MAHA Mine in India， with low efficiency and resources wasted seriously problem， through comparing various mining methods comprehensively， the room and pillar mining was changed to comprehensive mechanized solid filling mining， the roadway arrangement plan was put forward. After matching test， main material waste rock filling and the ratio of fly ash of supplementary material were settled， the key part of filling transportation system vertical feeding system preliminary design was conducted. Comparing to room and pillar mining， comprehensive mechanized solid filling mining realized safe and efficient recovery of coal resources.
