GJ963138 德国的石灰石矿开采作业使用斗轮式挖掘机〔刊,英〕/Prokopy S.∥RoekProd.—1994,97(7).—41～44德国 Hanover 东部的 Teutonia Cement公司采用大孔径爆破石灰石矿,并用液压挖掘机堆积装载,皮带机输送和列车运输的联合作业,过去年产量为1200000t。从1991年初开始,使用斗轮挖掘机,经过实机使用证明,该机取代了原有的采掘工艺,单位时间的开采量大幅度增长,每吨石灰石综合开采费用减少了61%。图4表2 (南英)GJ963139 应用斗轮式挖掘机采掘含粘土岩石和褐煤时,切屑尺寸对铲斗阻力的影响模型
GJ963138 Bucket Wheel Excavator for Mining Limestone Mines in Germany [British, English]/Prokopy S. ∥Roek Prod.-1994, 97(7).—41-44 Teutonia Cement, east of Hanover, Germany, uses large-bore blasting limestone ore , And the use of hydraulic excavator stacking, belt conveyor and train transport joint operations, the past year’s output of 1200000t. Since the beginning of 1991, using a bucket wheel excavator, the actual machine has proved that the machine replaced the original mining technology. The amount of exploitation per unit time has increased significantly, and the comprehensive mining cost per ton of limestone has decreased by 61%.
