The mid-and short-term stratigraphic base-level cycles are identified. High-resolution sequences are divided based on the above results. The study shows that the stratigraphic base-level cyclic method is an efficient way in the determination of the high-resolution sequences, especially in the classification of tbe terrestrial and transitional depositional succession.展开更多

This calculation method can be used to calculate more accurately the convergence quantity of consolidated rocks in the broken zone of the working face. In addition, case analyses by using the introduced calculation method were conducted and satisfactory results were obtained.展开更多
