In order to prevent energy accumulation in rock burst face, the mining speed should be controlled, and until the pressure is released, the recovery can be carried out. However, in the repetitive mining of three layers of coal, high-temperature fire points occurred many times. To prevent the coal seam fire in rock burst face, the coal seam water injection method can be used to increase moisture, soften the intensity of coal, and reduce the accumulation of energy and the appearance of high-temperature spots.%冲击地压工作面为防止能量积聚，工作面要控制推采速度，待压力得到释放后再进行回采。然而3层煤复采，发生过多次高温火点。为防止具有冲击地压的工作面煤层发火，采用煤层注水法可增加煤层含水率，软化煤体强度，降低能量的积聚，同时又减少高温点的出现。
