Zusammenfassung: | The invention relates to a coal raking machine and a coal mining method utilizing the coal raking machine. The coal raking machine comprises a driving part, a driven part and a transmission link part,wherein the transmission link part comprises an annular transmission chain which is detachably mounted at a raking head, and the two ends of the annular transmission chain are separately engaged withchain wheels of the driving and driven parts so as to achieve circulating reciprocating movement. During coal mining, interior of upper and lower gate roads is subjected to loosening-borehole-drilledexplosive-loaded blasting towards a coal bed of a working surface, thus, coal mass can fall into slotted holes, then, the driving part is started up, coal self-slides into or is driven to slide intothe lower gate road through the raking head and enters a scraper reloader for being conveyed away, then, the coal raking machine and the reloader are closed down, and the coal raking machine moves forwards under the drive of a h |
