摘要 ： The Upper Paleozoic strata in the southern Qinshui Basin was strongly deformed, and the prediction of CBM sweet spots in this area is difficult. Stress is an important factor affecting the permeability of coal reservoirs. Therefore, the influence of strong denudation on coalbed methane enrichment was studied in this paper. The results show that stress unloading, reduction of formation temperature, and tensile strain, all can lead to the reduction of the minimum principal stress in the erosion process. The cumulative reduction of minimum horiaontal stress for the No. 3 coal is generally less th
