Abstract:Aiming at the problems of repeated commands and paramenters input，a lot of auxiliary calculations and operations，and a lot of time and labor consuming in the programmatic numerical simulation，taking the gob-side entry driving with roof cutting and pressure relief method in Longquan coal mine as the engineering background，the connotation of numerical simulation modular modeling was discussed and FLAC3D5.0 and 3DEC5.2 softwares were used.The following conclusions could be drawn：the simulation process was split into several sub-modules，such as：modeling module，boundary fixing module，constitutive relation parameter assignment module，excavation workface module，excavation roadway module，roof cutting pressure relief module，anchor rod（cable）layout module，image extraction module，monitoring data extraction module，data visualization module，etc.Each sub-module ran independently as a“black box”and could be combined and nested；The internal relationship of the sub-modules was clear，the external interface was standard，and it coul be transplanted and redeveloped to realize the“building block”call in cross-model modeling.The modular numerical simulation modeling method used the least parameters to represent the most variables，which could greatly improve the efficiency of model modifying and parameter research.with the least parameters，calculated more parameters automatically.It could generate a model by modifying a parameter；change a series of parameters，get a series of figures and tables bychanging a series of parameters.The operation process was unattended and the task was shutdown automatically when it ended.A lot of effort was required to build the “black box” of modules，however，in the long run，“one-stop service”could be provided for comparative study of parameters and cross-model development by modular modeling，which could save time and energy for the majority of researchers.
