Mining area needs to be more fluid

The trucks are consistently getting stuck in my mining areas and creating havoc on my supply chain. They need to be revamped to make it so the trucks don't bury themselves. I had all my mines working fine, but for some reason my limestone trucks and excavators were consistently stuck and path unknown. I did nothing different on these and even when I first tried setting up the mines I was doing something wrong as they wouldn't dig correctly. I just think the mines need more work to make them bit more fluid.
