Abstract

The layer of the North wing filling mining area in a certain coal mine uses the Ordovician limestone as coal-bearing strata rock, the Quaternary pore confined aquifer in the overburden is developed. Study the height of water flowing fractured zone after filling is significant to achieve safety mining. This study is based on equivalent mining height, using three methods of theoretical calculation, numerical simulation and similar material simulation to forecast the height of water flowing fractured zone in a certain coal mine, respectively. It is obtained that the heights of water flowing fractured zone are 12.72, 12.50 and 14.28 m, respectively. The result indicates that the three methods match well by comparison, and it provides important theoretical basis to mining engineering practice under water in a certain coal mine.
