Gentlemen,
I would like to hear your opinion about our project.
We found a rock that looks like a door/wall (attached: Rock1) which we dug towards it facing east. While digging, we noticed that its like a passage where the flooring and ceiling are flat (about 6ft). Can anyone advise if Rock1's sign ((like a V shape line) meant something?
As we dig through, in about 3 ft we've seen the 2nd rock/wall (attached Rock2). Both of these rocks/wall are like hard cement, its so hard that cause too much dust when jackhammered.
Are we on the right track? Someone said we need to penetrate the same kind of rock/wall for 5 times, before we enter a chamber. Is it true?
Any thoughts please?
Thank you in advance.
