| 摘 要： | 提出冲击矿压的强度弱化减冲理论，即采取松散煤岩体，降低强度和冲击倾向性，使得应力高峰区向岩体深部转移，并降低应力集中程度，使发生冲击矿压的强度降低，使得煤岩体中所积聚的弹性应变能达不到最小冲击能，从而防治冲击矿压的发生.强度弱化减冲理论在三河尖矿的生产实践中得到了有效的验证.

| Abstract: | Put forward the intensity weakening theory for rockburst, it is the strength and rockburst liability of the coal-rock body reduced to weaken the danger of rockburst by the loosing coal-rock body. The peak district of the stress move to the deep department of rock body and the concentration degree of the stress. The intensity of rock burst is reduced after taking the measures of weakening rockburst in dangerous district of rockburst. The rockburst is eliminated when making the elastic energy below the standard with prevention methods. The intensity weakening theory for rockburst was got effective result in production practice of Sanhejian Mine. |
