| The Transmissivity of Fufeng Nappe Structural Belt in Huainan Coalfield |
| Cambrain limestone and sandy mudstone were pushed onto the Permian coal measures by the Fufeng thrust in Huainan coalfield. It is very important to understand the hydrogeological features of this thrust, because it threats safe mining under the Fufeng thrust block. Petrochemical composition of Fufeng thrust was determined and its water-bearing property was analyzed. The authors studied microfeatures of tectonite in Fufeng faulted zone, analyzed water stability of media in the faulted zone and found out favorable conditions for groundwater runoff by slaking test. In addition, the opening and closing properties of Fufeng faulted zone were studied by limestone etch test and carbonate balance principle. It is concluded that Fufeng nappe structural belt belongs to open system and has the essential conditions for groundwater intake and runoff. It therefore has water-transmission capacity. The transmissivity of the Fufeng fault zone increases with the expansion of the mining scale. The correctness of these conclusions have been proved. |
