随着我国长壁开采造成呆滞煤量的不断增加,应用短壁机械化开采工艺将不宜开采的煤层采出,提高煤炭采出率,是当前开采技术水平下回收煤炭资源的有效途径。论述了一种适应于短壁煤层高效、安全综合机械化开采的纵向摆动截割臂短壁采煤机的设计和研制。 With the increasing amount of sluggish coal caused by longwall mining in our country, it is an effective way to reclaim coal resources under the current exploitation technology by applying the shortwall mechanization mining technology to mine the coal seam which is unfit for mining and improve the coal recovery rate. This paper discusses the design and development of a short-wall shearer with longitudinal oscillating cutting arm adapted to the efficient and safe mechanized mining of short-wall coal seam.
