Boring machines come in various sizes and uses, we tend to associate them with tunnel construction as in the London Tubes, Channel Tunnel and the new London Cross rail project?
But there are as many used in a variety of roles from water well sinking to the present day need of fracking. Many of the surface drillers are set up for short-term workings, where as the boring machines are constructed under ground and when the jobs are completed they are buried or encased.
Smaller boring machines where developed for the mining industry to take men off the coal face, but today many are no longer used.
Despite computer or robotic automation, humans are still required to clear obstacles and this has lead to some very serious and devastating accidents in China, Russia and South-America.
