Investigation of Strong Strata Behaviors in the Close-Distance Multiseam Coal Pillar Mining by Hongwei Mu, Yongsheng Bao, Dazhao Song, Dongfang Su

“…Moreover, a theoretical model for the mechanism of strong strata behaviors in the close-distance multiseam coal pillar mining was established, which was validated by the monitoring data of seismic computed tomography CT, microseism, and electromagnetic radiation (EMR). Furthermore, the results of the study indicated that the main factors affecting the strong strata behaviors were the static stress concentration caused by the overlying coal pillars and the dynamic disturbance caused by the fracturing and slipping of the overlying coal pillars and roof under the influence of mining. …”
