摘要

为了有效防止老顶板重放顶板事故的发生,自采煤工作面开始开采以来,应用SOS微震监测系统对工作面进行了全程监测与测量。统计分析微震事件的入射频率和事件总能量的周期性变化,从而推断出老顶板断裂的周期性。结果表明,煤工作面周期加权与事件总能量周期变化存在对应关系。在强微震活动发生之前,会有一个弱震活动期,弱震活动对强震发生起到能量积累的作用。释放总能量的周期加权在一定范围内波动,但波动变化的不稳定性增强。

Fully-mechanized coalface periodic weighting analysis based on the SOS micro-seismic monitoring system
In order to effectively prevent the roof caving accidents occurs of the old roof weighting, the SOS microseism monitoring and measuring system was applied to the full time monitoring and measuring on the working face since the beginning of coalface mining start. Statistical analysis of micro earthquake events, incident frequency and event total energy periodic changes, thus deduce the old roof fracture periodicity. The results showed that coalface periodic weighting and event total energy periodic changing existence corresponding relationship. Before the strong micro-seismic activity occurred, there would be a weak seismic activity period and the weak seismic activity would play the role of energy accumulation to the strong seismic occurred. Releasing of the total energy in periodic weighting fluctuates in a certain range fluctuations, but the instability of fluctuation changes enhanced.
