摘要
为了预测大采高开采工作面煤壁片帮的准确区域,利用地震波CT技术对工作面前方的震波传播异常区进行了测定。根据波速与应力的关系推断出应力异常区,由此推测出工作面推进过程中的片帮区域,为煤壁片帮预防及防治措施的制定提供准确的地质依据。
In order to predict the accurate rib spalling area in the large mining height mining face, this paper uses seismic wave CT technique to measure the anomalous area of seismic wave propagation in front of working face. According to the relationship between wave velocity and stress, the stress anomaly area is deduced, and the area of the slice is predicted. The conclusion of the study is to provide accurate geological basis for the prevention and control of coal wall.Keyword： large mining height seismic wave CT rib spalling prevention
