Roof Fracture Characteristics and Strata Behavior Law of Super Large Mining Working Faces

Roof Fracture Characteristics and Strata Behavior Law of Super Large Mining Working Faces

Exploiting the working face in coal mines using a super long mining length and large mining height has become important for intensive production with high yield and high efficiency. The paper develops a roof structure model to analyze the influence of 195 m, 242.4 m, and 376 m working face lengths a...
