摘要
提出了采动应力监测理论,开发研制了采动应力监测系统,并进行了采动应力场监测实践,针对冲击危险工作面进行了监测和预测。监测实践表明,采动应力监测系统能够准确监测采动影响条件下工作面前方煤岩体的应力变化,据此能够有效评价工作面前方冲击危险区的冲击危险等级,为冲击矿压预测与防治提供了先进、适用手段。
This paper put forward a theory of mining stress monitoring and developed mining stress monitoring system. Practice of mo- nitoring and predicting for mining face with bursting danger showed that this system could precisely monitor stress variation of coal body ahead of mining face. This system could be used for effectively evaluating rock-burst danger degree and provide an advanced and adaptable method for rock-burst prediction and prevention.
