Rise Coal Mining in Fully Mechanized Caving Face with Large Inclination Angle and Inclined Longwall

This paper describes the profile of Dayang mine 3204 fully mechanized caving face and the situation of the large inclination angle rise mining process.By taking appropriate safety measures,the technical problems appeared in the mining process such as coal wall spalling,bracket dumping,shearer declining are solved,which successfully completes the large inclination angle rise mining in inclined longwall fully mechanized caving face.
