煤矿高效开采技术与装备的最新发展

Recent Development of Coal Mine Highly Effective Mining Technology and Equipment

介绍了国外煤炭高效开采技术与装备的发展概况,系统总结了近年来我国在智能化开采、超大采高、大采高和超大采高综放等方面取得的重大技术突破;介绍了实现0.6~1.3m薄煤层、中厚煤层智能化高效开采的技术途径及效果;剖析了6~8m,8~20m特厚煤层一次采全厚开采技术难题,介绍了超大采高综采及综放关键技术及装备。

It illustrated development situation of coal highly effective mining technology and equipment of foreign, and systematicallysummarized important technological breakthrough for intelligent mining, super large mining height, large mining height and super largemining height fully mechanized coal caving mining and so on, and also introduced intelligent highly effective mining technology and it’s effect of thin and medium-thickness coal seam, which coal seam thickness was 0. 6 ~ 1. 3m, also introduced the mining difficultytechnology than one pass cutting coal mining in extra thickness coal seam, which coal seam thickness was 6 ~ 8m, 8 ~ 20m, the keytechnology and equipment of fully mechanized mining and fully mechanized top coal caving with super large mining height.
