An Object-Oriented Approach for the Recursive Numeration and Visualization of the Key Strata of Coal Mines

The exploitation and utilization of coal resources have caused serious ecological and environmental problems that are closely related to the movement and destruction of the overlying strata, especially the activities of the overlying key strata (KS). The existing KS calculation methods are character...
