摘　　要：强化开采是软破矿岩开采的一项重要技术措施,也是间接控制地压的一种手段。根据地压显现的不平衡性和分区性以及尽可能提高回采效率的要求而进行分级强化开采是一新的探索。本文介绍了分级强化开采的依据、措施和效果。Xiaoguanzhuang Iron Mine is one of most difficult deposits to mine in China with its complicated pattern of orebody, soft and broken ore and rock, gently angle of inclination, deep location and high cover pressure. And mining of its west section has to be operated in the abutment area. Intensified extraction is an important technique for mining under such conditions.It is a new search and practice to conduct sub-graded intensified extraction to increase mining efficiency according to unbalanced distribution...
