Study on fracture mechanism and stability control of longwall working face with thick hard roof in coal mine
This study investigates the spatial fracture mechanics of thick and hard roofs during working face advancement through theoretical modelling and physical simulation. To address the limitations of the traditional Euler–Bernoulli beam theory for thick roof conditions, the Timoshenko beam theory is introduced to establish...
