Feasibility Study on Paste Filling Replacement Mining Technology under Layered Mining


	of Thick Coal Seam

Filling mining is an effective way to liberate the‘three unders’coal，prevent surface sub⁃

sidence and realize the sustainable development of coal resources.Based on the background of Dongshan Gu⁃

cheng Coal Mine in Shandong Province，the feasibility of paste filling replacement mining for coal under

buildings is analyzed，and the optimization measures are put forward.The results show that the implementa⁃

tion of paste replacement mining filling project can effectively solve the problem of coal mining under build⁃

ings in Gucheng Coal Mine，alleviate the shortage of coal resources，reduce the impact of surface subsid⁃

ence，and improve the economic benefits of coal mines.The proposed optimization measures provide techni⁃

cal reference for similar mines.
