| Abstract: | The former coal column of 80 metres thick at seam 13-1 is renewed after analysis has been made on the structural geological condition,hydrogeological condition,the cover rock's textural types and bedrock's weathing character of shafts.Further,a calculation formula is given for the set-up of a water-proof coal column.It is important for the recovery of coal resources and rather the increase of economic efficiency. |
