摘要
以缓倾薄层锰矿床的地层特征、原岩应力等为基础，简述了锰矿床开采技术特征，采矿方法及相应地压活动规律与现状；针对花垣、遵义、鹤庆、斗南等锰矿山由房柱法开采所引起地压隐患，提出了相应的处理原则与方法．
Based on the ground behaviour of the gently inclined thin manganese deposit and the intact rock stress, a description is made on features and methods of mining the deposits, and the law and current status of the related underground pressure activities. A principle and method is developed for dealing with hidden danger in underground pressure caused by the pillar and chamber working on mines of Huayuan, Zunyi, Heqing and Dounan.
