淮南煤田北西向断裂与岩溶陷落柱关系研究
|
摘要
为了揭示淮南煤田岩溶陷落柱(带)发育方向的形成原因,为工作面安全通过岩溶陷落柱提供对策,通过对淮南煤田近东西向的复向斜构造盆地调研分析,掌握了发育的3组主构造线分布特征,并结合淮南井田实见岩溶陷落柱(带)的分布特点,对淮南煤田北西向断裂与岩溶陷落柱(带)的发育方向的关系进行了研究。结果表明:该北西向的张扭断层是北西向的岩溶陷落柱(带)发育的基础条件,即在可溶岩内的北西向张、张扭断层存在的条件下,为地下水运移提供了条件,从而出现了矿区今发现的规模宏大的北西向岩溶陷落柱(带)。
In order to reveal the formation causes of the karst sinkhole /zone development direction in Huainan Coalfield,thus the measures for mining face safely passing through the karst sinkhole could be provided. With the analysis on three main structure line distribution features developed in the east and west directional synclinoria structure basin of Huainan Coalfield,in combination with the distribution features of the karst sinkholes in Huainan Coalfield,a preliminary study was conducted on the development direction relationship between the north-west directional failure of Huainan Coalfield and the karst sinkhole / zone. The results showed that the NW tensile and tension torsional faults were the basic conditions of the NW karst sinkhole / zonedevelopment. Under the existed conditions of the NW tensile and tension torsional faults in the soluble karst rock,those conditions could provide the basis to the underground water migration and thus large scale NW directional karst sinkholes / zones found in the mining area.
