Hypothetically speaking
If you are extracting 6.5 million tons of coal per annum from thar coal project, you need thousands of people to extract coal. In average coal power project you probabaly create 30% jobs for power project, 30% for transportation and another 30-40% for mining so you are talking aboit thousands of jobs from each project.
Then we talk about Gwadar port, International Airport and the planned city of Gwadar. Many Airports in the world alone creates 30,000 - 40,000 direct and 120,000 indirect jobs so I guess even if Gwadar is just 20% of larger Airports, expect minimum of 20% jobs... Thats mimimum of half million jobs in total we are talking about and millions of indirect jobs as is evident from the project. There will be plenty of industrial parks, free zones and factories established along the route for both domestic and International trade and will create huge number of jobs
