巷道与钻孔交叉三维数值建模方法
3 D grid modeling method of roadway borehole intersecting
摘要
Abstract
A mesh morphing method is proposed and a program based on FISH is written,which has pa-rameterization and reusable features,as there are difficulty and inefficient in FLAC3D modeling. The grid is generated by brick unit in this program. Then the grid position is calculated according to the geomet-rical relationship of roadway borehole intersecting. And the grid is adjusted by the program. In this way, an accurate model of roadway borehole intersecting is obtained. The stress of borehole under the influ-ence of roadway is studied by a calculation case of horizontal gas drainage borehole in mining seam. The stress state of borehole is accurately reflected according to the result. Feasibility and accuracy are veri-fied. This method is easy to understand and can quickly build a large number of models with different parameters. The difficulty of study on the roadway borehole intersecting is reduced. This method contrib-utes to understanding of the principle of modeling in FLAC3D and provides researchers with reference on depth of complex modeling mechanism.关键词
