大倾角倾斜长壁综放工作面仰斜开采工艺

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

摘要: 介绍了大阳煤矿3204综放工作面大倾角仰斜开采情况,采取相应的安全技术措施,解决了开采过程中出现的煤壁片帮、支架倾倒、采煤机下滑等技术难题,顺利实现了倾斜长壁综放工作面大倾角仰斜开采。

Abstract: 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.
