P-15BⅡ型耙斗装岩机是煤炭科学院上海研究所和福建省邵武煤矿机械厂共同协作针对原P—15B(SBZ)型耙斗装岩机存在的问题,于1980年进行改进和研制。 1981年完成样机两台,一台在福建省上京矿务局柯坑矿进行了连续六个月的工业性试验。工作面巷道断面5.9米~2,掘进进尺438.9米,累计装矸量约4600米~3(松散系数按1.6计)。另一台样机在湖南省隆回县观音
P-15BⅡ type rake bucket rock loader is the co-operation of Shanghai Institute of Coal Science and Shaowu Coal Mine Machinery Factory of Fujian Province in response to the problems of the original P-15B (SBZ) rake bucket rock loader, which was improved and developed in 1980. In 1981, two prototypes were completed and one industrial test was conducted for six consecutive months in Kekeng Mine, Shangjing Mining Bureau, Fujian Province. Working face tunnel section 5.9 m ~ 2, excavation footage 438.9 meters, the cumulative amount of gangue about 4600 meters ~ 3 (loose coefficient by 1.6 dollars). Another prototype in Longhui County, Hunan Province Guanyin
