See IIT DHANBAD is one of the pioneers in the geological science and engineering. So if you go for it then you will surely get enough scope from the university to get established in the field. Now I would say as both the institute are good you have to choose the field of your interest. IIIT Sricity offers CSE which may get you a better career prospect ahead if you are keen in coding. If you are interested in machines and want to explore and conceptualize machinery then IIT Dhanbad will be a great place for you. So both the career path are good but CSE can lead you to a more lucrative future where as in Mining you may not be able to see that kind of lucracy in future.
I would recommend you to decide based on your interest. If you need some references about both the fields then follow the link provided below:
