Abstract

The deformation and failure of overlying strata in mined out aera was produced by the traditional caving mining, and the distribution pattern of "three zones" was formed. In which the height of water flowing fractured zone is an important parameter for safe and efficient mining of "three down" coal seam. Therefore, it is very important to observe and analyze the height of "three zones" by reasonable means. Color borehole TV observation, detailed description of drilling process and core drilling integrity rate are used in the 8101 working face mining goaf Tongxin mine Datong coal mine group to observe the height distribution of "three zones". And comparised with the theoretical calculation results in fully mechanized caving mining, The results show that color borehole TV observation, detailed description of drilling process and core drilling integrity rate to test the height of "three zones" in fully mechanized top coal caving is reasonable and accurate.
