北七采区3下7110工作面是田陈煤矿的主采工作面，该工作面受冲击地压威胁，特别装备了 KJ21冲击地压在线监测系统，利用该系统监测煤体应力，预测预报冲击危险性，确定超前支承应力影响范围。
北七採區3下7110工作麵是田陳煤礦的主採工作麵，該工作麵受遲擊地壓威脅，特彆裝備瞭 KJ21遲擊地壓在線鑑測繫統，利用該繫統鑑測煤體應力，預測預報遲擊危險性，確定超前支承應力影響範圍。

The 7110 coal face of third coal seam in the seventh north mining area is the main coal face of Tianchen coal mine. The coal face is threatened by rock burst.In order to monitor the stress of coal,we installed a Online monitoring system of rock burst named KJ21.The system can predict the possibility of rock burst and determine the advance support stress influence range.
