Zusammenfassung:The invention provides a complex coal seam rock burst ground reverse inclined shaft area source control method, which comprises the following steps of: based on complex geological conditions and related parameters of a fully mechanized caving face of a steeply inclined coal seam, obtaining the elevation and the inclination angle of a coal seam mining area through field measurement; wherein the fractured well is divided into a vertical part and an inclined part, the inclined part is perpendicular to the inclination direction of a coal seam mining area, finally, the specific arrangement position and the arrangement length of the fractured well are determined according to the grade strength of the impact tendency of the coal seam, and finally, drilling and fracturing processes are carried out according to the design to reduce the impact ground pressure in the coal seam. Safety production of mine work is guaranteed, and social benefits and economic benefits are remarkable. 本发明提供了一种复杂煤层冲击地压地面反向斜井区域源头控制方法,基于急倾斜煤层综放
