摘要
The Wolong coalmine is one of mines seriously influenced by magmatic intrusions in Huaibei mining area,China. Because the geological structures are vital factors controlling the regularities of magmatic intrusions and the distribution of igneous rocks, the tectonic stresses field and geological structures formed before geological time of magmatic intrusions were thoroughly investigated. The analysis results indicated that the direction of magmatic intrusion was controlled by the NNE-trending faults (F7 and F5), and the channels of magmatic intrusions were faults F7, F5 and F15 that was intersected by fault F5 besides.
