difficult problem. Because it will bring many mining hazards such as ground
subsidence, roof water inrush and water body destruction. To solve these problems
in Tongjiaowan mine, the method combining with strip mining and backfilled mining
is proposed. First the coal seam is divided into several strips along the trend
and the width between two strips is ten meters. Then the coal seam of every
strip is caved in turn from up to down. After mining every strip, the mined-out
area is filled with filling materials immediately. The example simulation results
show that the strip mining method is feasible and the filling effect of high
strength filling material is the best. This research may be a better suggestion
on resolving the problem of the steep coal seam mining under water body. The
study method would also be a reference for other kinds of mining conditions
including mining beneath buildings or railways.]]>Zhang, F.,201234849Liu, C.Y., P.J. Yang, C.J. Hou and Z.J. Wan,20042166169Li, Y.M., C.Y. Liu, X.M. Li and N.B. Zhang,2010914191425Li, Y.M., Y.H.
