该文采用KJ550型应力在线监测系统和SoS微震监测系统对1306工作面支承压力分布特征及矿震时空分布规律进行了研究。研究结果表明,工作面“见方”期间超前支承压力影响范围高于正常推进期间,工作面强矿震的出现不是单一孤立的,强矿震有丛集显现,震动与开采活动的直接相关性很强。1306工作面重点防冲区域为工作面正常推进时周期来压位置,工作面“见方”区域及断层、煤层分叉及巷道交叉等地质异常区域。
該文採用KJ550型應力在線鑑測繫統和SoS微震鑑測繫統對1306工作麵支承壓力分佈特徵及礦震時空分佈規律進行瞭研究。研究結果錶明,工作麵“見方”期間超前支承壓力影響範圍高于正常推進期間,工作麵彊礦震的齣現不是單一孤立的,彊礦震有叢集顯現,震動與開採活動的直接相關性很彊。1306工作麵重點防遲區域為工作麵正常推進時週期來壓位置,工作麵“見方”區域及斷層、煤層分扠及巷道交扠等地質異常區域。

Distributing characteristic of abutment pressure and law of mine earthquake in workface of 1306 was researched by KJ550 on-line stress and SOS micro seismic monitoring system. Results show that inlfuence range of advance abutment pressure during workface square is larger than workface normal promoting, strength mine earthquake is not isolated, Key regions of coal brust prevention and control is position of periodic weighting, face "square" area and faults, seam splits and other geological anomalies roadway crossing area.
