随着厚煤层、超厚煤层工作面开采工艺的发展,综采放顶煤技术也成为综采工作面开采的重要高产高效的开采方法,但后部刮板输送机卸载方式的发展却一直局限于端卸形式,结合前部刮板输送机卸载方式的优点,通过对不同卸载方式的研究,设计出综放工作面后部刮板输送机新型卸载方式的机头,提高工作面生产效率。 With the development of mining technology in thick coal seam and ultra-thick seam, fully mechanized top coal caving technology has also become an important high-productivity and high-efficiency mining method for fully mechanized face mining, but the development of rear scraper conveyor unloading method has been limited Combined with the advantages of the unloading mode of the front scraper conveyor, this paper designs the head of the new unloading mode scraper conveyor at the rear of the fully mechanized caving face through the research of different unloading ways, and improves the working efficiency of the working face.
