【摘要】 为了分析同忻井田岩体应力空间分布特征及其与矿压显现的关系,利用地质动力区划方法对井田范围内的活动断裂进行识别和划分,以所划分的活动断块为构架,通过岩体应力状态分析系统计算确定了井田岩体应力状态,划定了高应力区、低应力区和高应力梯度区。结合矿压观测数据分析了矿压显现与岩体应力状态之间的关系,确定同忻井田矿压显现主要受到由活动断裂产生的高应力控制。研究结果可为同忻井田矿压显现预测及其控制提供指导。更多还原

【Abstract】 In order to analyze the relationship between Tongxin mine field rock mass stress space distribution characteristics and strata behavior,active faults of mine range are identified and classified by geo-dynamic division.Then active fault blocks were as framework to determine mine field rock stress state by rock mass stress-state analysis system,high stress area,low stress area and high stress gradient area are divided in the range of mine.Combined with the mine pressure observation data analysis of the relationship between strata behavior and rock mass stress state,so as to determine the Tongxin mine field strata behavior mainly was controled by high stress which were affected by active faults.The research results could provide guidance for prediction and control of Tongxin mine field mine strata behavior.更多还原
