Abstract

Aiming at the problem that programmatic numerical simulation involves tedious repeated input of commands and parameters as well as a large number of auxiliary calculations and operations, which is time-consuming and labor-intensive, this paper takes the gob-side entry driving with roof cutting pressure relief in Longquan Coal Mine as the engineering background, and discusses the connotation of the modular modeling concept for numerical simulation, as well as its application and effect in studying the above problem by using 3DEC 5.2 software. Decomposing the simulation process into several sub-modules can greatly improve the efficiency of model modification and parameter research. In the long run, the modular modeling concept and method can provide a "one-stop service" for parameter comparison research and cross-model development, thus saving substantial time and energy for researchers. Different simulation software packages have distinct programming techniques; therefore, we should adapt measures to local conditions and adopt an approach that integrates the modular modeling concept with the specific features of the simulation software in use.
