Problems solved by technology

[0002] There are mainly two existing test methods for coal seam permeability: one is the laboratory measurement method, which has the disadvantage that it is only effective for bottom permeable coal seams, and the other is the direct measurement method of well testing, which has the disadvantage that it can only be measured on site , and most coal seam permeability test methods can only use existing coal samples or prepared coal samples, and cannot truly simulate the coal seam cleat distribution
