【 摘 要 】

According to the fact that surface subsidence is the result of the deformation through effect of transfer and superposition by each rock (soil) layer in the coal overburden, the paper proposed the basic principle and conditions of the stratification transfer prediction, and established a new prediction method based on transfer effects of the rocks (soil). The application result of this new method in 14021(3) workface of Panji coal mining area locates Anhui province show that not only does the stratification transfer prediction method of the mining subsidence have higher prediction accuracy in general than the probability integral method, but also improve significantly the prediction accuracy in the edge of the subsidence basin, the precision can be increased more than 80%. So, it could provide better technological support for prevention of mining subsidence in Panji coal mining area, Anhui province.
