Abstract: Coal mining in deep coal mine was threated by complex dynamic disaster combined rock burst and coal-gas outburst, taking the typical complex dynamic disaster in Pingdingshan No.10 Coal Mine as a study subject, the characteristics and conditions of complex dynamic disasters were analyzed.The coal rock mass prope rties and gas, stress condition and mining disturbance was the essential condition for complex dynamic disaster.According to the test results of Pingdingshan coal minin g area, three sensitive indexes of complex dynamic disaster were put forward, drilling cuttings weight, initial speed of gas emission from borehole and gas desorption C ontent, and the concrete calculation method was also given.Finally, the area and local measures to control complex dynamic disaster were achieved, such as exploiting the protective seam, gas drainage, pressure relief by drilling boreholes and so on.
