基于ANSYS的构造应力场模拟分析——以任楼煤矿7_2煤层为例

Analysis of Tectonic Stress Field Molding Based on ANSYS——A Case Study Based on Conditions of Coalbed 7_2 in Renlou Coal Mine

为判别井田内主要构造断裂的导水性,利用ANSYS软件,对任楼井田72煤层构造应力场和断层受力状态进行了模拟分析,表明该井田断层导水性受多期构造应力场,尤其是燕山二期构造NEE向主压应力控制,使井田南部F3至F5之间大中型断层及井田北部NE向断层普遍出现淋水现象。

In order to estimate water permeability of big tectonic faults in mine field, tectonic stress field and pressure in faults of Coalbed 72in Renlou Coal Mine were simulated and analyzed with software ANSYS. The results present that water permeability of the faults in the mine field is controlled by multiple stage tectonic stress field, especially by principal compressive stress in NEE direction of Yanshan diehophase tectonic, which caused water spray from big and intermediate faults between F3 and F5in the south of the mine field.
