摘　　要：为了查明地质动力区划确定的活动断裂的存在与地下分布状态对煤与瓦斯突出的影响,利用质动力区划方法对鹤岗兴安井田区域内活动断裂进行划分,建立了板块构造学和矿井工程实际的联系。通过野外考察选取了对兴安矿煤与瓦斯突出影响严重的Ⅲ-1和Ⅳ-3活动断裂为研究对象,进行EH4电导率剖面测量,最终确定了两条活动断裂的空间分布状态。研究表明活动断裂控制着煤与瓦斯突出的区域性分布,EH4活动断裂电导率测量提供了活动构造探测新方法,对矿井动力灾害危险性预测和井下开采具有指导意义,可以在矿井实际工程中应用推广。In order to find out the influence of the existence and underground distribution state of active faults determined by geo-dynamic zoning on coal and gas outburst.Faults within Hegang mine are divided by using geo-dynamic zoning.Then the contact between the plate tectonics and mine engineering is established.Faults Ⅲ-1 and Ⅳ-3 which have great influence on coal and gas outbursts of Xingˊan mine are selected as researching object through field investigation to do EH4 conductivity profile measurement.Finally,the space distribution state of the two active faults is determined.The research indicates that the regional distribution of coal and gas outbursts is controlled by active faults,EH4 active faults conductivity measurement provides a new method for detecting active structure,which has guiding significance in mine power hazard prediction and underground mining,and can be applied and promoted in actual project.
