Influence Factors Analysis for Safety Mining Face Under Complex Goaf in Close Distance Seams

According to the characteristics of close distance coal seam mining, taking the 31202-1 working face in Shigetai Coal Mine as an example, combined with the position relationship of the working face and the deployment of the surrounding mining, under the influence of multiple factors of multi-layer goaf and small coal mines goaf, we carry out scientific analysis on the safety mining of working face, three aspects from the working face of “two tunnels and two lines” and key prevention and control area of crossheadings, the overlying 22^# coal and 12^# coal goaf, small coal mine goaf are proposed by influence of complex mined out area in 31202-1 working face mining.
