摘要

摘要: 为了解工作面冲击危险状态,提前采取防冲措施,降低后期防治强度,理论分析了集中静载荷与冲击地压发生的相关性,建立了基于集中静载荷探测的冲击危险性预评价模型,并开展了实践验证。结果表明：集中静载荷在冲击地压启动过程中起主导作用,并可在工作面开采前探测并卸载;区域性集中静载荷可通过地震波法探测得出,基于地震波参数建立的冲击危险性预评价模型能够对工作面危险性做出评价,并且能够指导预卸压工作实施和检验解危效果。

Abstract: In order to understand dangerous situations of work face, to take prevention measures in advance and to reduce late treatment intensity, the correlation between concentrated static load and rock burst is analyzed. A model for burst hazard assessment is established based on the detection of centralized static load, and it is put into practice. The results show that the concentrated static load plays a dominant role in the initiation of rock bursts, and it can be surveyed and unloaded before the mining of work face. The regional centralized static load can be surveyed by using the seismic CT. The proposed model for burst hazard assessment based on seismic wave parameters can be employed to evaluate the dangerous situations of work face and to guide the implementation and check of the control effect of prevention and cure work.
