为预防邻近采空区侧回采巷道繁发冲击矿压,根据动静载叠加诱发回采巷道冲击破坏模型,采用理论分析的方法,揭示了邻近采空区巷道冲击破坏机理及其冲击地压频发的理论依据,基于动静载主要构成得出了邻近采空区巷道冲击破坏的2种模式以及必要准则,从而提出了降低动静载叠加影响的邻近采空区巷道外错布置技术,并且确定了巷道降低静载避开支承压力集中区以及削弱动载以增大传播介质衰减指数为原则的巷道布置原理,最后邻近采空区巷道外错布置技术在跃进煤矿得到了成功实践,取得了明显、有效的防治冲击地压效果。

In order to prevent rock burst hazard of roadway near the goaf in advance, the paper used theoretical analysis to reveal the mechanism of rock burst fail ure and theoretical basis of frequently rock burst for roadway near the goaf, which was according to the model of rock burst failure of roadway under dynamic load and static load. Based on the main components of the dynamic load and static load, two models and necessary criterion were concluded. The lateral layout technology of ro adway near the goaf was proposed to reduce dynamic load and static load. And it was determined that the principle of lateral layout which avoided concentration area 0 f bearing stress to induce static load and increase attenuation coefficient of the propagation medium to weak dynamic load. Finally, the technology was successully pra cticed in Yuejin Mine. Significant and effective effect of rock burst prevention was achieved.
