| Abstract: | By using the method of numerical simulation through the finite element method,it showed that this way could be applied to the digging of under-well laneway and in the same time to analyze the stress,displacement and strain. It can improve the stress distribution and reduce the burst of the gas effectively. This paper present the results that the reasonable digging method can change the stress convergence of rocks and reduce the burst of gas by digging step by step through the method of numerical simulation ... |
| Keywords: | numerical simulation digging plan stress model |
