摘　　要：倾斜中厚矿体的开采是国内外矿山开采中普遍存在的一个技术难题。对国内外倾斜中厚矿体的开采现状进行了总结,并研究了其开采特点和发展趋势。介绍了国内倾斜中厚矿体多采用空场法回采、机械化程度低、矿石回收率低,国外以充填法为主、机械化程度高、资源回收率高,但成本也很高的现状。提出了倾斜中厚矿体应向机械化程度高、高效率、高回收率、低成本的方向发展。Mining of inclined medium thickness ore body is a technical problem in mine mining at home and abroad. The present mining situation of this ore body at home and abroad is summarized, and its mining characteristics and development trend are studied. The open-stope mining is generally used in mining of the ore body in China, which has a low degree of mechanization and a low recovery of ore. The back-filling method is used in mining of the ore body abroad, which has a high degree of mechanization and a high recovery of resources. However, it has a high cost. It considers that mining of the ore body should develop towards high degree of mechanization, high efficiency, high recovery and low cost.
