Filling up the Mine Goaf with River Sands along the Yellow River for Flood Prevention
Some coal mines have been exploited along the downstream of the Yellow River recently. Mine goaf will lead to ground subsidence and affects the security of the watercourse and the embankments. This article focus on the analysis in the following five aspects: the gravity of geological disaster caused by mine goaf, the successful experience of dredger excavating sand in the Yellow River, the feasibility and the unit price analysis of filling sand in the mine goaf, and the benefit of filling sand. Filling up the coal goaf and replacing the coal column with the Yellow River sediment, and exploiting most of the supported coal. These methods will not only enhance the coal mining rate, and reduce the waste of coal resources, but also eliminate the ground subsidence of the mining area because of exploiting, eliminating the influence of the channel and embankment caused by the man-made geological disaster, and ensure the flood prevention and geological security of the mining area.
