煤柱宽度变化区微震监测冲击矿压前兆信息分析

Analysis of Rock Burst Precursory Information with Microseismic Monitoring at Coal Pillar Width Variation Area

摘要: 以某矿2102工作面回风巷为研究对象，统计分析其掘进过程中过煤柱宽度变化区的微震监测数据，研究矿震参量变化规律、分析强矿震前兆信息，并提出煤柱宽度变化区冲击矿压防治措施，取得了良好的控制效果，保障了掘进面过煤柱变化区的安全生产。

Abstract: We take 2102 working face return airway in a mine as the research object, and carry out statistical analysis of the tunneling process changes in coal pillar width by the microseismic monitoring data, study mine earthquake parameter change law, analyze strong mining-induced earthquake precursor information, and propose the coal pillar width changes area rock-burst prevention measures, and achieve good control effect, which ensures the safety production of heading face to pass through the coal pillar variation areas.
