Description

technical field [0001] The invention relates to the technical field of engineering safety monitoring, in particular to an experimental device for simulating convergence deformation of an underground roadway and a method for using the same. Background technique [0002] Today, our country is in a period of rapid economic development and transformation, and various industries are developing rapidly. At the same time, large-scale energy mining and application and the rapid increase in production scale have caused us to face more serious security issues than before; The roadway deformation and collapse accidents caused by mine pressure instability have become more serious, posing a huge personal threat to underground workers. [0003] With the depletion of shallow coal resources in my country, the depth of underground mining is increasing. In the deep high-stress environment, the shallow rock formations with hard rock characteristics show soft rock characteristics, and the surro...
