根据郓城煤矿微震监测系统的监测结果，分析了1300工作面开采强度和推进速度对微震活动的影响、1300工作面微震事件能量分布和工作面内微震活动分布规律。结果表明：微震活跃度与开采强度和推进速度成正相关，推进度的剧烈变化会导致大能量事件发生；并通过对微震事件分布规律的分析确定了1300工作面开采影响范围和高冲击危险区域。
根據鄆城煤礦微震鑑測繫統的鑑測結果，分析瞭1300工作麵開採彊度和推進速度對微震活動的影響、1300工作麵微震事件能量分佈和工作麵內微震活動分佈規律。結果錶明：微震活躍度與開採彊度和推進速度成正相關，推進度的劇烈變化會導緻大能量事件髮生；併通過對微震事件分佈規律的分析確定瞭1300工作麵開採影響範圍和高遲擊危險區域。

According to the monitoring results of micro-seismic monitoring system in Yuncheng Coal Mine,the influences of mining intensity and advance speed on micro-seismic ac-tivities in No.1300 working face,the energy distribution of micro-seismic incidents,and the dis-tribution law of micro-seismic activities were analyzed. The results indicated that there was a positive correlation between the micro-seismic activities and the mining intensity or working face advance speed,the macro-energy incidents happened when the face advance changed violently. Through the analysis of micro-seismic incidents'distribution law,mining influence ranges and the dangerous zones of high impact were analyzed and determined.
