苏联矿山主要使用中央破碎站,其位置在井筒附近(少数在矿体旁)。在使用井下破碎站的初期,每个生产中段都建立破碎站。破碎装置要破碎的铁矿石储量为400～2000万吨(表1)。以后,每2～3个中段建立一个破碎站,每个破碎装置负担的矿量增加到3000～4000万吨以上。1949年德聂伯罗彼得罗夫斯克省的一个矿 The Soviet mines use mainly central crushing stations, which are located near the wellbore (a few are beside the ore body). In the early stages of using a downhole crushing plant, a crushing plant was set up in each production center. Broken devices to be broken iron ore reserves of 400 to 20 million tons (Table 1). In the future, a crushing plant will be set up every 2 to 3 middle stages, and the amount of ore burdened by each crushing plant will increase to over 3,000 to 40 million tons.
