The non-pillar self-forming roadway N00 coal mining method is a new mining process technology based on the longwall mining roof-cutting short-wall beam theory and is a major technological change in coal mining technology. Relying on the "China Mining Science Collaborative Innovation Alliance" platform, the company has developed the world's first set of non-pillar self-forming roadway N00 mining method complete scraper conveyor equipment, providing technical and equipment support for realizing no roadway excavation in coal mine working faces, integrated mining and retention in non-pillar mining, and safe continuous production.
Technical Features:
◆ Matched with specialized equipment such as coal shearers and hydraulic supports for the non-pillar self-forming roadway N00 mining method to realize integrated safe, efficient, intelligent, and green mining of cutting, excavation, transportation, roof-cutting, support, and protection.
◆ The new H-type low-height telescopic tail, used in conjunction with the coal shearer, realizes integrated cutting into roadway, coal loading, and coal transportation.
◆ Self-adaptive coal blocking, coal guiding, and coal collecting device, with functions of front coal blocking, top coal guiding, and bidirectional coal collecting, which can be adjusted in multiple dimensions to adapt to changes in the working face.
◆ Telescopic coal shoveling and coal conveying device with triangular prism box structure, stable and reliable, effectively cleans floating coal and levels the floor, ensuring smooth advancement of coal mining.
