Dynamic simulation study on protective coal pillar width on floor roadway

Determination of reasonable protective coal pillar width has a great significance for the safety and stability seam working face surrounding structures facilities. For studying pillar, based on platform ABAQUS, program with PYTHON language to make dynamic model which can simulate changes different width. Then, deformation law floor roadway under protection is analyzed. The finite element optimization analysis compiled MATLAB, minimum used as goal calculation model, proposed. optimized (37.65 m) ensure overall by comparing calculated results between designed value Through comparison simulation result field monitoring data, validity rationality method are verified. parametric modeling proposed in this paper greatly improve efficiency analysis, provide certain reference similar engineering.
