遵照伟大领袖毛主席“开发矿业”和“扭转北煤南运”的指示,目前,我国正大力开发南方煤田。在南方煤田中,缓倾斜极薄煤层占有很大比重。但是,国内尚无适应于开采这种煤层的采煤机械。实现缓倾斜极薄煤层采煤机械化,为当前急需解决的重要课题。根据燃化部提出在缓倾斜极薄煤层实现综合机械化开采,以减轻工人同志的笨重体力劳动,提高劳动生产率,增加煤炭资源回收的任务,重庆煤炭研究所于1965年底,对四川省缓倾斜极薄煤层的开采情况进行了调查,并提出了刮斗铇煤机组的研制课题。
In accordance with the instructions of Chairman Mao, the great leader, “developing the mining industry,” and “reversing the operation of northern coal in southern China,” at present, our country is vigorously developing the southern coal field. In the South Coalfield, a very large proportion of gently inclined very thin coal seam. However, there is no domestic coal mining machinery suitable for mining this coal seam. To realize the mechanized coal mining with gently inclined extremely thin coal seam is an important subject urgently needed to be solved. According to the Proposal submitted by the Ministry of Fuel Oil to implement comprehensive mechanized mining in the gently inclined extremely thin coal seam in order to reduce the heavy manual labor of comrades in workers, improve labor productivity and increase the recovery of coal resources, the Chongqing Institute of Coal Research Thin seam mining conditions were investigated and put forward the scraping bucket 铇 coal generating unit research topics.
