| 摘 要： | 采空区治理工程具有其特有的隐蔽性和复杂性,在注浆工程结束后很难准确的把握注浆工程效果,采用钻孔电视探测技术对某电厂的地基注浆处理效果进行了探测分析,结果表明,通过彩色钻孔电视观测,可以准确的了解注浆前采空区覆岩的空洞分布、裂隙发育情况以及注浆后浆体充填空洞、裂隙的详细情况。

The Application of Bore-hole TV Exploration Technology in Detection of Grouting Effects in Goaf Area |
| |
| Abstract: | The goaf governance engineering has unique concealment and complexity,it is very hard to understand the grouting effect accurately after grouting.The paper makes detection analysis on the grouting effect of a power plant by bore-hole TV exploration technology.The results show that the distribution of cavity,the development of rock crack before grouting and the state of cavity and crack after grouting can be understood accurately. |
