为了提高开采能力,美国制造了采用柱式采矿法和矿房式采矿法的JOY型连续工作的康拜因。美国用人工开采煤矿的平均生产能力为8吨/每人/每班,而采用机械化开采时生产能力如下:1.采用风镐、截煤机、装岩机等生产时——35吨/每人/每班。2.采用截盘式JOY型康拜因时——50吨/每人/每班。3.采用旋转钻头式JOY型康拜因——80吨/每人/每班。4.采用遥控JOY型康拜因时——100吨/每人/每班。由于欧洲一般不采用柱式采矿法和矿房采矿法,故在欧洲JOY型康拜因仅应用于巷 In order to improve the mining capacity, the United States manufactured JOY-type continuous working Combine using the pillar mining method and the mining method. The average production capacity of artificially mined coal mines in the United States is 8 tons per person per class, while the production capacity under mechanized mining is as follows: 1. When producing with picks, cutters, rock-mounted machines, etc. - 35 tons / Person / class 2. The use of cut-off type JOY Kang Baine - 50 tons / person / class. 3. Rotary drill JOY type Corbin - 80 tons / person / class. 4. Using JOY-type Kang Bain remote control - 100 tons / person / class. As Europe generally does not use column mining and mining mining law, so in Europe JOY-type Kang Bainen only used in the lane
