Abstract
The karst collapse is one of the main environmental geological problems, which affects and restricts the social and economic development in karst area. Through monitoring, the changing process of karst caves can be observed. It includes extent, location and stress. Further, the monitoring data can provide data support for prediction of karst collapse and avoiding disaster. This paper systematically introduces the main monitoring work according to the problem of karst collapse. In order to systematically provide the references of karst collapse monitoring techniques and methods, and to provide basic support for mechanism research of karst collapse, we propose the monitoring contents and corresponding monitoring techniques, methods and means. In the end, it is pointed out that the focus of monitoring for karst collapse in the future is to combine the advanced and traditional monitoring techniques together.
