Investigation of the partition failure process and energy evolution in coal-rock composite structure under free surface unloading

Unloading failure of the coal-rock (CR) system is the key factor leading to rock burst disaster. Therefore, it is very important to explore the failure mechanism of the CR system by laboratory test. Initially, CR composite samples underwent laboratory tests with unloading pressure at various rates (...
