多软件联合的煤矿三维数值建模方法及其应用

为了解决复杂三维地质模型构建耗时费力、难度大的问题，提出了一种联合多个软件的复杂三维地质模型快速构建的方法，以钻孔信息为基础资料，利用3DMINE建立岩（煤）层等高线，以dxf文件形式导入GOCAD生成岩（煤）层点阵数据文件，利用SURFER对点阵数据进行网格化处理，导入RHIRO软件之中生成ANSYS可读取的iegs文件，经过ANSYS划分网格后导入FLAC3D中进行数值计算。以山东郓城煤矿的地质模型构建为例进行介绍，给出了以该方法进行地应力反演后得到的区域应力场分布云图。通过多个煤矿应用表明:该方法建模速度快，摒弃了繁杂命令流式建模方法，通过数据的逐步对接，减少了中间过程的人为干扰和误差，兼顾了ANSYS优良的网格划分功能和FLAC3D数值计算能力，且效果较好，可在其他领域和行业复杂地质模型构建中推广使用。

Method of 3D numerical modeling on coal mine with multi-software combination and its application

To solve the problems of time-consuming and great difficulty in the construction of complex 3D geologic model, a rapid modeling method of complex 3D geologic model with multi-software combination was put forward. Taking the borehole information as the basic information, the contour line of rock (coal) stratum was established using 3DMINE. The exported dxf file of 3DMINE was imported into GOCAD to generate the lattice data file of rock (coal) stratum, then the gridding processing of lattice data was carried out using SURFER. The results were imported into RHIRO software to generate the iegs file which can be read by ANSYS. After grid division by ANSYS, they were imported into FLAC3D to carry out the numerical calculation. Taking the geologic model construction of a certain mine in Shandong province as example, the distribution nephogram of regional stress field obtained after in-situ stress inversion by this method was presented. It showed that the method has rapid modeling speed, abandons the modeling method of complex command stream, reduces the human disturbance and error of the intermediate process through the gradual connection of data, and gives consideration to the good grid division function of ANSYS and the numerical calculation ability of FLAC3D, with a better effect. It can be popularized and applied in the complex geologic modeling of other fields and industries.
