Height determination of water conducting fractured zone in backfill mining with paste-like material
ZHANG Feng-yan
Abstract：To get a deep insight into the fractured zone characteristics of overlying rock of backfilling mining working face, researchers combined voussoir beam model and theory of material mechanics, and proposed a method for height calculation of water conducting fractured zone, which was used in 10803 working face of Hongyang coal mine and the result was 13?38m. According to the physical detection on the fractured zone of 10803 working face the height was 13?2m. The theoretical calculation result matched with the physical detection result, which showed that the proposed method was applicable and feasible for analyzing the height of fractured zone of overlying strata.
