and adding that big of tubes to pressurize the trap may over pressurize it. the ventouri effects still apply. you have fast water being shoved into a chamber that gets smaller and smaller. so how can you say it won't effect it. then why does the mini work? the hole box creates a venturi system all by itself. but it also restricts the flow so it wont over pressurize the trap and blow stuff out instead of fluidizing it. This is something I spent a long time working on. I made sure I new exactly what and how they work. building my forge. And I spent countless hours talking to experts like Ronald Reil. a man who's got tons of PHD's including Fluid dynamics and geology and has spent many hours working with forges and mining equipment. if you look up how to build a propane forge or even the store bought forges you'll see his designs on the burners

. there's only a few that are different. one is a Swedish design and they have a hole lab that sits and test different equipment and build there's only after a couple hundred hours of testing and running it on the computer to make sure everything is coefficient.

then there the T-Rex Burner.

Rex and Ron built it together. the combination of a mongo burner and the Reil burner. they're know 1 of the best industrial burners for some of the leading smelters and even Nasa.
then theres the mongo burner witch isn't used very much because they produce allot of heat but end up melting down the burner and possibly blowing up

Ron and this other guy built them but there not advised just because of that. even Ron will tell you to avoid them. There's others out there but there just rebuilds of the same things. people trying to reproduce what the Rex burners can do.
Him and Ron are working on a new 1 that will produce allot more heat in small area. but he won't tell me much more than that. people have already tried to steel the Rex burner and have gotten hit with patent lawsuits.
I may not be an expert on the area but I'm well versed in ventouri systems.
it doesn't matter when you restrict something in such a manner it will build speed and pressure. look at the river itself. now on the zook you take 2 large cones and use them for your water intake to the tubes your going to increase the pressure quite a bit. it's not going to send it into space but it may be enough to over power the trap and blow it out instead of fluidizing it the way it should be. if your running on a slow river with very little drop it'll probably work great. but your going to have to hand clear the screen witch is counter productive to the bazooka. but you stick it where you'd normally put a Bazooka and get it so the overburden clears like it's supposed to then it might blow the trap out instead of fluidizing it. that's all we've been saying.
It's why I haven't modified mine. I've thought about it but just bearly to make it so it works better in slower water. but then why would I do that if I move a little bit up or down stream I can find a place that works just as well.
the video on blow mining where just to show a cool venturi effect. the funnel that the material is blown into isn't the driving force on that. they have a big water pump that pumps the water through the large hose then the spray hose, it's just a small hose. then NV it hits a venturi to speed it up more so that the dabree blown into the hopper will get blown through the hose. the the cone/hopper and then the exit port witch can be added to a highbanker or a sluice box.that thing would work great on a Bazooka I think but I'd have to test it. it's actually a smart idea instead of sucking things of the bottom you can blow it all into the hopper. I can see it being a great tool and being able to cover more ground faster. cause you'd be blasting down in the cracks and blowing everything out of them right into the cone.
