What would be a ballpark cost figure for Rock excavarion per CY in US$.
Operation includes Drilling, filling explosive, Blasting and removal on side of the excavation (only pushing 100'aside) No loading and hauling.

price is also dependent on your locale, size of job, size requirements, placement requirements, hauling rates, etc. i've seen blast rock pay rates be $10-50+/cy (again depending on several factors). you should track down some relatively local folks that can give you some candid estimates based on the project details.

I just bid on a job of 400,000 cu/yds and it went for under $5.00 per/cu/yd.
Mind you, these are Canadian numbers but powder costs are close.
Either way I'll bet it should go for well under $10.00 cu/yd
RE: Rock excavation
I believe you are talking about the blasting only. That price does not include buldozing the exploded material??

When I stated I could "beat miningmans price" that was not intended as a jab against you (or your qualifications) but was intended as a fun spirited poke at all the drillers and blasters on the forum whom wanted to competitively bid on 8705's project. I hope you did not take it the wrong way.
I work all across Canada and bid on any size blasting project from British Columbia to Ontario, I very seldom go farther east although I consulted on a large project in New Brunswick last year.
Some recent examples for you from the past several weeks.
I missed a quarry of 65,000 cu/yds. I was planning 0n 5 ½ to 6 inch holes 12x12 or possibly 12x15. I bid the job at $3.80 per cu/yd and did not get it. Apparently it went for $2.80 per cu/m. There were no buildings nearby and no blasting mats required.
Last week a road job with 110,000 cu/yds went for $5.50 per cu/yd to drill, blast, supply blasting mats (but not swing them) and supply 3rd party vibration monitoring.
This project would have an average of 16 ft. holes drilled with a 4 inch bit on a 10x10 pattern. Granite
I just completed a 55,000 cu/yd site prep job and did very well at $4.50 per cu/yd. We were lucky as the holes were bone dry so we were able to use mostly ANFO. We used 4 inch bits on a 10x10 pattern and did not require blasting mats.
But having said this...these prices are down from the previous few years. As some blasting contractors that have drills sitting are dropping prices and working as low as cost plus 5% just to keep key people working and for cash flow. The problem I have with that is that it does not take much of a problem on a construction site for cash flow to turn into negative cash flow.

My main work area is Western Canada / NWT and I have a BC Class 1 unrestricted WCB ticket so I am sure you recognise my credentials. I wonder if we have met each other previously? Perhaps we should make an attempt to make direct contact. I am unsure of the rules / ethics of providing personal contact info on this site.
