Abstract: The overlapping of coal and gas resource mining rights in the Xinjie Taigemiao Mine Area has made it difficult to coordinate the planning and development of resources. Based on this, the paper investigates the "coal-gas" collaborative mining mode in the three-dimensional overlapping area of mining rights through methods such as research retrieval, theoretical analysis, and numerical simulation. The research shows that: ① The adverse scenarios of coal-gas cross mining mainly include corrosion of coal seams in underground gas well pipes, mining through abandoned wells, damage to surface settlement pipelines, and other economic and technical impacts. The mining mode can be classified into gas first, coal later, coal first, gas later, and collaborative cross-mining modes based on the relationship between time and space. The article provides targeted planning and layout for the natural gas corridor in the mining area. ② Under the "coal-gas" collaborative mining corridor mode, the recovery of corridor-protected coal pillars will create isolated working faces. The stress distribution characteristics of isolated working faces combined with the deep mining conditions in the mining area will further induce the principle of dynamic disasters. The arrangement of short and long working faces in the last stage of super-long working face recovery is conducive to stress regulation to weaken coal and rock dynamic disasters.
