为了适应中、小煤矿薄煤层炮采工作面的运输需要, 根据地方小煤矿地质构造复杂、工作面条件恶劣的情况, 针对13型和17B型刮板输送机存在的问题,按照煤炭部颁发的MT15-82《工作面用刮板输送机系列型谱》的要求,煤科院太原分院与运城拖拉机厂共同研制了SGD-320/18.5型刮板输送机。该产品通过型式试验和井下工业性试验,各项性能均达到了设计要求。在山西省机械工业厅组织下,于1987年9月3日通过技术鉴定。
In order to meet the transportation needs of medium and small coal mines mining face with thin seam, according to the local small coal mines complex geological conditions, the working conditions of the poor conditions for the 13 and 17B scraper conveyor problems, in accordance with the Ministry of Coal issued MT15-82 “face with scraper conveyor type spectrum” requirements, Taiyuan Branch Academy of Coal Mine and Yuncheng jointly developed SGD-320 / 18.5 scraper conveyor. The product through the type test and downhole industrial test, the performance has reached the design requirements. Organized in the machinery industry in Shanxi Province, in September 3, 1987 passed the technical appraisal.
