摘　　要：为了研究矿区岩体应力状态,利用地质动力区划方法研究了区域地质构造,建立了区域地质模型,计算了构造应力场并划分出高构造应力区和高构造应力梯度区,分析了岩体应力状态与巷道稳定性、开采沉陷、矿山压力显现等的关系。研究结果表明:基于地质动力区划方法进行的区域岩体应力状态评估结果对于巷道支护设计、开采沉陷预计、矿压显现预测等采矿工程的设计和实施工作具有重要的指导意义。In order to study the rock mass stress in coal district, a regional geotectonic model is established by using the geology dynamic division.A regional geotectonic stress field is computed, the high stress area and high grads stress area is zoned and the relation between stress field and laneway stability, mining sink and mining pressure are analyzed. From the result, the stress status evaluation based on geology dynamic division has important significance for the design and implementation of coal mining engineering.
