Abstract
The basic concept of force in coal mechanics consists of external force and stress. The external force is generated from the outside of coal seam and can be further divided into two types, surface force and body force. Surface force is applied to the coal surface, such as gas pressure, coal support force and the contact forces between different coal blocks. Body force, such as gravity and inertia force, is continuously distributed within the coal and is also called a mass force.
