Abstract

The invention provides a contact-non-contact combined dangerous rock mass monitoring and early warning method, device and equipment. The method comprises the following steps: constructing a three-dimensional model of a dangerous rock body; generating a two-dimensional model of the dangerous rock mass based on the three-dimensional model, and obtaining a two-dimensional joint network model of the dangerous rock mass by using an image processing technology; obtaining feature information of each joint based on the two-dimensional joint network model of the dangerous rock body; performing region division on the surface region of the dangerous rock mass to obtain a plurality of statistical regions, and obtaining the number of joint groups in each statistical region, the line continuity coefficient of joint surfaces and the density of the joint surfaces; determining a high-risk area in which instability may occur in the plurality of statistical areas; monitoring data sent by the contact type monitoring instrument in the high-risk area are obtained, and judgment and early warning are conducted on the stability of the dangerous rock mass in the high-risk area based on the monitoring data and the joint macroscopic development condition of the high-risk area. The monitoring and early warning method provided by the invention has the advantages of low monitoring cost and high monitoring efficiency.
