Influence of Tectonic Region Ground Stress on Coal and Gas Outburst in Jiulishan Mine Field

In order to analyze the influence of ground stress in tectonic area on coal and gas outburst, by theoretical analysis, field measurement and laboratory experiment and combined with method of numerical simulation, the in-situ stress state in Jiulishan Mine was divided; the distribution laws of Jiulishan Mine ground stress is obtained; partition map of stress state in tectonic region of mining area is drawn.
