    Panzers: I break rocks thread

    This is not the time of year for me to start/ continue a cool project for the new board. So instead I’ll start a thread on what I do for a living. I’ll try and make it interesting, informative and ill answer any questions you have.

    So I’m a small aggregate producer/mine owner. I have a few sand and gravel pits and one hard rock quarry. I have 2 portable crushing spreads, 2 screen plant spreads and a stationary washplant. Lots and lots of iron.

    Today’s post will be about me getting ready to loosen some rock in my hard rock quarry. My quarry is tree covered so first step was to clearcut the area and stump and remove topsoil and overburden. The pit is awesome in that the bedrock is anywhere from 0 to 4’ down. There is not much material to remove. The material we move is getting placed where we need to build a sight berm to meet our conditional use permit.

    This is pretty straight forward we use our quad axle dump trucks and a excavator to move the material. Once the ground is stripped down to the solid rock or hard pack granite the driller comes out and plots the pattern. He is planning to use a entire truck full of powder so that will give us 20-22,000/ton of shot rock.

    The driller stopped out this afternoon and started to mark the shot. We are drilling 3.5” holes on a 8x8 staggered pattern. Depths range from 24 to 29’. Once the driller left me and dad took the transit out and used it to paint drill depths for the driller to drill to. The driller loves this step as he doesn’t have to guess. It helps create a nice flat floor.

    Here are a few pictures of the quarry and the area we have stripped off. Hopefully you guys enjoy this stuff.

    So is it a blow a section at a time thing? Or just one big bang?

            Did you choose Thumbnail to get that gallery?

            I'm lazy, I'd rather scroll.

            We had part of a Slinky. But I straightened it.

              Yup about 120-150 holes at a time will get shot. It will make a nice pile of work for me lol

                So my wife for me a drone for Christmas I should be able to fly it and record the shot. I asked last year If I could fly a drone over and the blasters did not give a fuck. I just need to practice flying a bit lol.

                  I’m still learning how to post pics. I used the camera button and that is how they turned out, I wanted them bigger but there was no option to do so from my phone. I believe Austin was working on a fix,

                    So the max the blasters will shoot is one truck load of powder at a time which in our stone is about 20-22,000 ton. The guys that bring the powder is a company called orca. They have a proprietary system which uses electric caps to set each hole off at the correct time. The electric timing is awesome for getting a high quality blast without a large shock wave fly rock or air burst. It puts the power into breaking and moving the rock vs tossing it around and making a mess.

                    There will be 120-150 holes and no two will go off at the same time. It’s really cool. Hopefully I’m around the day of the shot so I can take a bunch of photos while helping to load the holes.

                      Im always hiring people who show up and want to work! I only blast 3 times a year or so it’s all I can afford/need to do. This blast will cost me over $30,000 ;(.

                          20,000lbs or so. A full tandem axle truck worth. The explosive is actually a foaming liquid. They pump it down the holes then plug the hole at a certain height with a plastic plug. The explosive expands to fill all the voids in that hole. I’ll have more photo once the powder truck comes.

                            There was an episode of 'The Explosion Show' on Science Channel that shows this process. Worth the watch.

                            My old employer had mobile crushing equipment. A lot of work was contracted to local towns to make road gravel. Is this something you do also?

                              Yeah: I only have 2-3 months of work for 1 spread In my own pits. The rest of the time we go and crush for whoever is yelling the loudest. It’s fun and challenging as each pit presents a different challenge to make in spec material. Just when we get it all figured out it’s time to pack up and head to the next one. I almost prefer working for other people as I get paid for the entire pile a few weeks after we are done. Versus making big piles at home and selling it 20 ton at a clip.

                              Today project my big spread is at home crushing my dirty gravel into 3/4” dense base. If we didn’t get 3” of rain last Sunday and Monday that guy can put our 5-600tons a hour of that material.

                              The plant I’m running today we are making 3/4” recycled base. Recycle is tough because of all the foreign material in the pile. All it takes is one stump one 4x4 post a Leicester of angle to ruin your day. Last Friday we found a 3x3x3/8 x 4’ long peice of angle iron. It couldn’t make the bend in the breaker and took my 48” wide belt and turned it into 2 24” wide belts. All my fault because I didn’t see it when I was prepping with the hoe. Now one to blame but myself.

                              ill get some pictures today of the shit show!
