Stuck Underground!-part 1

I looked down at my trembling hands. They were covered in wet dirt. My finger tips were raw from digging at the dirt wall for hours. I wasn't crying anymore. I already cried my eyes out the first 2 days. I realized that crying won't do anything. I had to get out of here. But, where was I?

I woke up in this dirt hole 4 days ago. I think its a hole. It is some sort of pit. Its just big enough for me to stand up and lay down so it must have the deepness of 6 feet and radius of 7 feet. There is a strong smell of rot emanating from the dirt walls. The ground seems to be covered in mulch but I am not sure. It is too dark in here to make out anything. I felt around the walls for the hundreth time hoping that there is something. After failing to find anything other than rocks and old roots, I started to dig at the wall once again. My finger nails bent and broke as I dug my raw hands into the wet walls. The humid air of the pit filled my lungs. That's when I heard it. I felt it at first. Some light rumbling from the wall that I was digging at. Then the whole pit begin to shake violently. I could hear wirling sound coming from the wall I was facing. It became louder and louder. I couldn't stay on my feet anymore because it was shaking too much. I sat on my bottom like a fool waiting for the rumbling to stop.
The wall of dirt and rocks crumbled before me. Through the cracks yellow lights flowed. It almost blinded me and I sheilded my eyes while still struggling to see. A giant drill poked through the wall. More light entered the pit I was in.  The drill was spinning at a high speed but slowed as the body of the machine emerged from the hole it just made. The machine had two bright lights right behind the giant drill it carried. A man in a hard hat was pushing the machine. I coughed violently as I whipped dirt off my face. I tried to speak to ask him where I was and who he was. I realized that dirt was in my mouth and made it hard for me to speak.
"We detected life signals a few days ago. We didn't think you would still be alive," the man yelled over the machine's engine. "I am glad you made it. We have to hurry!"
"What the hell is going on? Where am I?" I asked.
"You must hit your head pretty hard. No time to explain right now. Hurry follow me," he said as he grabbed my tattered shirt.
What else was I suppose to do? So, I just followed him back the way he came from.
