This paper studies the collapse structure, plastic failure regularity, and overburden movement regularity in the mining process of the Shallowly Buried Coal Seam (SBCS) group in the Yulin area using physical similar material simulation, computer numerical simulation, and theoretical analysis. The objective of the present article is to explore the strata behavior regularity of the SBCS group, taking the engineering geological conditions of Hongliulin Coal Mine as the sample. According to the results, when the lower coal seam of the SBCS group is mined, the initial stress step increases, and the periodic stress step decreases compared to the upper first coal seam. During the mining of the lower coal seam, there is an extreme collapse span in the interlayer rock formation: the process induces the activation of the collapsed roof in the goaf of the upper coal seam, and the overall sinking phenomenon occurs. The dynamic stress is obvious. The roof stress is significant in passing through the upper coal seam's residual coal pillar (CP) into the lower coal seam. The CP is at a certain distance, and the residual CP is violently unstable and sinks the strata behavior regularity. The interlayer rock layer forms an inclined shear staggered fracture zone along the coal wall. The research results provide a theoretical method for controlling mine stress and green and safe mining in the SBCS group of coal production enterprises.

proceso de minería del grupo Veta de Carbón Somera (SBCS, literal del inglés Shallowly Buried Coal Seam) en el área de Yulin a través de simulación material, simulación numérica computarizada y análisis teórico. El objetivo del presente estudio es explorar el comportamiento regular del grupo SBCS con las condiciones ingenieriles y geológicas de la mina de carbón Hongliulin como ejemplo. De acuerdo con los resultados, cuando se extrae la capa más baja del grupo SBCS el punto de tensión inicial aumenta y los puntos periódicos de tensión disminuyen en comparación con la capa más alta de explotación. Durante la explotación de la capa más baja hay un punto de colapso extremo en la formación rocosa entre capas: el proceso induce la activación del techo colapsado en el socavón de la capa superior de explotación y el fenómeno hundimiento general ocurre. La dinámica de la tensión es evidente. La tensión del techo es determinante cuando pasa a través del pilar de carbón de la capa superior de explotación hacia la capa inferior. El pilar de carbón se encuentra a una distancia determinada y su residual es bastante inestable. La capa de roca forma una zona de fractura escalonada de corte inclinado a lo largo de la pared de carbón. Lo resultados de la investigación proveen un método teórico para el control de tensión al interior de una mina, y procedimientos de minería verde y segura para las empresas productoras en el grupo SBCS.
