煤矿井下运输中巷,一般是沿煤层走向掘进。由于地质构造复杂,煤层走向变化大,运输中巷弯曲较多。按常规铺设刮板输送机、普通带式输送机,不是台数多耗电大,就是刷修巷道工程量大。资兴矿务局宇字煤矿工程技术人员和机电工人,在学习外单位经验基础上,克服许多困难,终于将一台SD—22型不可伸缩、不可弯曲吊挂式带式输送机改制成可伸缩与可弯曲的输送机。该机于4月6日安装在井下24106运输道,安装长度167m,胶带宽度650mm,速度1.6m/s,实测负荷15kw,三处平面转角分别为
Lane underground coal mine transportation, usually along the seam heading. Due to the complicated geological structure, the trend of coal seam changes greatly and the lane in the transportation is more curved. Scraper conveyor according to conventional laying, ordinary belt conveyor, not the number of large electricity consumption, that is, large amount of brush repair tunnel. Zixing Mining Bureau Yu word coal mine engineering and technical personnel and mechanical and electrical workers in learning units based on experience, to overcome many difficulties, and finally will be an SD-22 non-scalable, non-bendable hanging belt conveyor can be converted into Telescopic and bendable conveyor. The aircraft was installed on April 6 in the underground 24106 transport lane, installation length 167m, tape width 650mm, speed 1.6m / s, measured load 15kw, the three plane angle were
