I assume the family area is the place to post this as it involves my family. In the begining of spring blasting people went around to other peoples homes to get approval to blast the mountain infront of our home (we live on the top of a mountain on the side of a valley (so we're high up facing the other side of the valley).....well they never came and talked to us however they talked to the neighbors directly beside us. Apparently they are blasting now...and the only reason I know is because I heard our roof crack THEN a split second later felt the shake and heard the boom....all my cats (three) freaked out and looked directly out the window towards the mountain. The roof cracking did not sound nice...., im also worried as we live above a very old mine on very soft ground from springs (probably from the mine being full of water) I have no idea how far it is down but i know fractures can happen and that kinda freaks me out lol. We rent from my parents so she (my mom) will be checking the roof when she gets home though i highly doubt if there is a crack that it will be that obvious though if it is that sucks! LOL! Just needed to vent. and whine about my phobia of falling into a mine LOL. I know my hubby drills for natural gas and when the second company comes in to blast the holes theres been times they cause MAJOR fractures in the ground....so just has me thinking lol. Anyone had to deal with blasting near them and experience any house damage?
