空芯包体地应力测量技术在煤矿中的应用

Application of Hollow Inclusion Geo-stress Survey Technology in Coal Mine

根据工程地质条件,岩体应力状态和地应力特征,合理有效地采用技术措施预防矿井动力现象,合理确定采矿采场布置及回采顺序。本文采用空芯包体方法地应力测量表明吕家坨井田是水平应力场,测量结果为矿井采场合理布局、巷道布置选择和锚杆支护设计提供基础数据。

Hollow inclusion geo-stress survey method indicates the stress field in Luijiatuo mine field ishorizontal. The measurement results supply base data for mine stope proper redistribution, tunnel disposal and anchor support design.
