| 摘 要： | 本文研究了北京西山地区现今构造应力场及因煤矿开采引起的岩爆和地面塌限两类地质灾害的特征。发现岩爆及地面塌陷严重的矿均处于高应力值区及拉应力区。认为岩爆和地面塌陷的生成条件和影响因素不尽相同，但它们都是因煤矿开采，围岩体应力平衡状态受到破坏而引起的。

| Abstract: | The present structure stress field and the geologic hazard in coal mine such as rockblasting and sureface breakdown which due to the coal mining in Xishan region of Beijinghave been researched. The author discovered that the coal mines where have strong rockblasting and sureface breakdown are all situated at the high stress field region and extensional stress field region. Although the generation conditions and effecting factors are different,the rock blasting and sure face breakdown should be caused by the destroy of stressbalance condition of rocks that due to the coal mining,and its also are the reflection of various destroies of mine alley deformation. The examination and application research ofcrustal stress field will be useful for understanding the generation and changing roles ofgeologic hazard,and the development trend of geologic hazard will be effective forecastedto guide the project design and mine mining. |
