在伟大领袖毛主席“开发矿业”的指示指引下,为了提高中深孔凿岩效率,74年由梅山铁矿、大庙铁矿、河北铜矿等组成的“三结合”研制组,对全国有关矿山作了调研后,于75年5月完成了本台车的设计,年底试制出2台样机,并在梅山铁矿进行了工业试验。一、用途本台车主要用于分段崩落法采矿进路巷道中钻凿平行及扇形炮孔用,有效孔深可达30米,亦可用于露天采场及港口建设向下钻凿炮孔,每天可钻凿炮孔300米以上。
Under the guidance of Chairman Mao’s “development of mining industry” under the guidance of Chairman Mao’s great leader, the “triple combination” research group made up of the Meishan Iron Mine, Dawang Iron Mine and Hebei Copper Mine in order to improve the efficiency of medium- After the mine was investigated, the design of the truck was completed in May 75 and two prototypes were manufactured by the end of the year. Industrial tests were conducted at the Meishan Iron Mine. First, the use of This car is mainly used for subsided mining approach roadway drilling parallel and fan-shaped hole, the effective hole depth of up to 30 meters, can also be used for open pit and port construction drilling down hole Drilling can be drilled more than 300 meters per day.
