一、详查区环境地质特征1.地震、地形地貌及稳定性评价。本区的地震根据“中国地震动峰值加速度图”所示,该区的地震动峰值加速度为0.05g,对照烈度Ⅵ度。2004年初,距该区40km的西乌珠穆沁旗发生了里氏5.9级地震。今后的矿区地面建设及井下施工时,必须采取防震与抗震措施,防患于未然,永久性建筑按Ⅵ度设防。区内地形较简单,地貌形态为舒缓波状起伏的中低山丘陵。
First, the detailed investigation of environmental geological characteristics 1. Earthquake, topography and stability evaluation. According to “Earthquake peak acceleration map of China” shown in this area, the peak acceleration of earthquakes in this area is 0.05g, and the control intensity is Ⅵ degree. At the beginning of 2004, a magnitude 5.9 earthquake hit Xihujumuqin Banner 40km away from the area. In the future mine ground construction and underground construction, must take earthquake and seismic measures, take preventive measures, permanent building by Ⅵ degree fortification. The terrain in the area is relatively simple, and the topography of the area is moderate and hilly with a gentle undulation.
