The essence of coal and rock’s physical and mechanical change process is the conversion of energy, and its deformation and failure process is a destabilization phenomenon driven by energy dissipation. The study of coal and rock failure from the view of energy conversion not only greatly simplifies the analysis of intermediate processes but also avoids the complexity and difficulty of intermediate processes and enables researchers to consider various affective factors holistically and comprehensively. To a certain extent, studying complex underground rock mechanics issues in coal mine from view of energy is easier to find the true cause of coal rock failure and get beneficial results. This chapter, based on studies on the porous characteristics and macroscopic failure mechanism of coal and rock mass, is aimed to analyze the macroscopic and microscopic mechanisms of coal and rock deformation and failure as well as the type of energy and its conversion behaviors in this process.
