摘要
Abstract
This paper took 16E10416 iflling working face of JiSuo coal mine as the prototype cable, using the similar material simulation method to study the development law of stope overburden stress, the results showed that the rule of stress development of roof and lfoor in the iflling stope had a certain degree of similarity, the stope roof stress undergone the process of transformation from"V"-type distribution to the"U"type, the roof and bottom stress can be divided into the stress concentrated area, the pressure relief zone and stress recovery of three zones, the results can be used as the base of ifeld measurement research and data analysis, can also be provide the theoretical basis for the overlying strata subsidence controlling of iflling mining.关键词
