| 中文摘要: |
| 采空区的存在不仅严重威胁着矿山的安全生产和附近居民的正常生活,而且还可能诱发地面沉降、地面塌陷等地质灾害,尤其是在其上方进行基础设施建设,更有必要对采空区的分布、位置、形态、大小及冒落等状况探查清楚。本文以北京景山学校门头沟校区拟建场地为研究区,从“探”和“查”两个方面开展工作,基本查明了采空区的分布情况。通过地球物理探测,推测出6处采空区异常区域,经过钻探工程验证与详细勘察,12个钻孔中发现了采空区或采后虚填物空洞,同时分析了场地的稳定性和抗震性,为场地开发建设及其安全性提供了设计和决策依据。 |
| 英文摘要: |
| The existence of mined-out area not only seriously threatens the safety of mine production and the normal life of nearby residents,but also can induce the occurrence of geological hazards, such as land subsidence,ground collapse, especially in the upper part for the construction of infrastructure,it is more necessary to clearly explore the distribution,location, shape,size,and inbreak etc. of mined-out area. This paper took the proposed site of Mentougou campus of Beijing Jingshan school as the research area, from two aspects of "exploration" and "check" to carry out the work,basically found out the distribution of the mined-out area,through geophysical exploration,6 goaf abnormal areas were inferred,after engineering drilling verification and detailed investigation,mined-out areas or postharvest virtual fill empty were discovered in 12 boreholes. At the same time,the stability and earthquake resistance of the site were analyzed,which provided design and decision basis for the development and construction of the site and its safety. |
