Predicting of Compact Rock Pressure and Precaution Measures in Taozhuang Mine

陶庄矿运用顶板动态、地音能量和钻屑量等监测方法对具有冲击危险的矿井进行综合监测,有效地预测到冲击地压的危险区域和地点,并采取媒体卸压解危措施成功地解陈了冲击地压危险。

This paper introduces a comprehensive monitoringmethod associated with predicting the compact rock pres-sure in Taozhuang Mine. The monitoring result shownthat: more than 90% of compact rock pressure was oc-curred in high stress zone in the front of the face and theintersection of isolated coal pillars; 75% of one in the po-riod of face weighting; the convergences of roof in theplace where compact rock pressure occurred were in therange of 40-95 mm. When compact rock pressure oc-curred it is that steep rise of convergences, rapid incre-ment of the energy of seismic sound and clear occurrenceof a peak of coal drilling. The hozord classes and hozordzones of compact rock pressure may be predicted accord-ing to the results of comprehensive monitoring. Throughtaking the measures of coal mass destress in the hozordzone, the compact rock pressure hozord can be dispelled,hance, it had been realized that for Taozhuang Mine toproduce in safety for 4 years.
