| 摘 要： | 提出了冲击矿压的强度弱化控制机理.通过深孔卸压爆破来弱化煤岩结构的强度,降低其聚能能力,释放所积聚的大量弹性能,使得煤岩体中所积聚的弹性能达不到最小冲击能;同时利用电磁辐射检验强度弱化治理效果,以达到消除或降低冲击危险的目的.通过在三河尖煤矿9202高冲击危险工作面以及济宁三号煤矿6303冲击危险工作面的现场治理实践,证明了该控制技术的有效性. |

| Abstract: | The strength weakening controlling mechanism of rock bursts in coal mines was put forward. The strength of coal and rock mass can be weakened through deep hole relieving shot, so the ability of energy accumulation is reduced, and a large amount of elastic energy accumulated in coal and rock mass is released, which makes it sure that the elastic energy accumulated in coal and rock mass do not exceed the minimum energy induced rock burst. Simultaneously, electromagnetic emission (EME) is used to check out the effect of eliminating or reducing the danger of rock bursts. The validity of this kind of control technology is fully proofed by the engineering practice of 9202 high-danger working face in Sanhejian Coal Mine and 6303 danger working face in Jining No.3 Coal Mine in China. |
| Keywords: | mining engineering rock bursts combined coal-rock strength weakening |
