摘　　要：针对俄罗斯煤矿现阶段的开采理念和综采设备使用习惯,采用现场调研与工业设计相结合的方法对俄罗斯南方矿煤层走向起伏较频、倾向有起伏且倾角变化较大的复杂条件下布置的综采工作面进行了设备选型配套研究。结果表明:利用刮板机机头、机尾"短槽"减小溜槽间垂直弯曲曲率半径,加快垂直弯曲速率,缩短弯曲段长度,较好地实现了倾角25°以下综采工作面交叉侧卸方式和工作面倾向因输送机机头、机尾垂直弯曲曲率半径过大而造成机头破底、机尾破顶量过大等问题;利用支架与中部槽之间的姿态校正油缸精确控制仰俯采角度技术及配套关系,保证中部槽在仰、俯采角度在±5°范围内能够精确控制,有效地防止了因走向起伏较频而引起的输送机"漂溜"、"啃底"问题,提高了工作效率,降低了含矸率。Aiming at the concepts of precise mining and reducing waste of resources of Russian coal mines,on-site investigation and industrial design are carried out on equipment selection for the fully mechanized coal mining face of the Russia Nanfang Mine,considering that the coal seam fluctuates frequently,the dip angle varies greatly.The results show that the scraper head and tail"short chute"are used to reduce the vertical bending curvature radius between the chute,speed up the vertical bending rate,shorten the length of the bending section,and better achieve the cross side unloading method of inclined working surfaces and it tends to cause problems such as the bottom of the head and the top of the tail being too large due to the large curvature radius of the vertical bending of the conveyor head and tail.The results show that the scraper head and tail"short chute"are used to reduce the vertical bending curvature radius between the chute,speed up the vertical bending rate,shorten the length of the bending section,and better achieve the cross side unloading method of inclined working surfaces and solve the problems of such as broken head and excessive tail break due to the large curvature radius of the vertical bending of the conveyor head and tail.Utilizing the technology of the attitude correction cylinder between the hydraulic support and the central groove to accurately control the tilting angle and supporting relationship,it is ensured that the tilting angle of the central groove can be accurately controlled within the range of±5°,which prevents the problems of"slipping"and"bottoming"of the conveyor caused by more frequent undulations.It improves the work efficiency and reduces the waste rate.
