摘要:
利用空心包体应力解除法对九里山矿进行地应力现场实测，得到不同位置和埋深的地应力实测数据，分析结果验证九里山矿地壳浅部以水平构造应力为主。以九里山井田区域内断层构造为骨架，建立三维有限差分地质模型。根据现场地应力测量结果，利用Flac3D软件进行数值模拟，模拟结果显示，断层存在会对原岩应力造成不同程度的扰动，造成原岩应力分布不均。在以上分析的基础上划分出井田应力增高区，应力降低区及应力梯度区
Abstract:
The test data of crustal stress at different location and burial depth were measured by using the stress relief method in Jiulishan coal mine. The results showed that the horizontal tectonic stress occupied the majority of superficial part stress in Jiulishan coal mine. A three dimensional finite difference numerical geological model was established based on the faults in Jiulishan field. According to the measuring results of ground stress, Flac3D stresswas applied to conduct numerical simulation. The result showed that the existence of faults influenced the primary rock stress in different degrees and leaded to uneven distribution of primary rock stress. Based on the above analysis, stressconcentrated area, stressrelaxed area and stressgradient area were divided.
