| Abstract: | Based on the geological features of the deep strata coal,the blasting parameters of wellbore expand for vertical and inverse well are studied.Numerical simulation is carried out from the depth of blasthole,explosive amount and wellbore stability using the LS-DYNA software,and compared with the traditional full face blasting.The results show that a good blasting result and production efficiency,as well as the wellbore stability,can be obtained using the parameters of the new blasting style. |
