M.Tech

You are a mining engineer and your desire is to do M.Tech in mining, but via distance education. You are already a mining engineer and hence I am sure you know how much practical training is required especially for this branch of engineering. I will perhaps say that this is one of the most intensive practical oriented branch of engineering. With this in background, I will say that there are very few Institutions which offer this course at post-graduation level. Since giving practical knowledge particularly at M.Tech level becomes a bit difficult. However I am attaching a link that will give you the places where you can do M.Tech in mining engineering. Once you do this you can pick out the places where it is available in distance education mode also and have a correspondence with them. I will however give you a word of caution that please ensure that the college which is offering you this is indeed attached to organized University and is current with their syllabus. Best wishes to you.

It depends on your area of interest. If you are interested in business or management orientation go with MBA. But, if you want to pursue or master a particular specialization, which you tend to do, go for M.Tech. Just make a clear decision about it as both are beneficial in terms if job aspects. You have other options like:
Construction management (it have many sub divisions - check NICMAR)
Structural engineering
Concrete technology
Ocean engineering
Irrigation engineering
Environmental engineering
Transportation
Remote sensing
Soil and foundation
Steel structures
Precast technology
Sustainability
If you have plan to start your own firm then go with construction management instead of doing MBA. You can also try structural, steel, precast engineering from some reputed institution. There is a lot of opportunities in foreign. Sustainability will be in high demand in near future.
