[@demolitiondavedrillandblast]

Like with most mechanical things, oil helps a lot.

[@gragor11]

Ahh the lubricator . . . I learned to drill underground in the stope school in the mine I was working in. You know the routine, hose down, scale, muck, perhaps lay track, fill lubricator, drill off round, load and hook up to mains blasting machine for detonation in all areas when everyone was out of the mine. And repeat for months. Then I graduated to my own stope and that's where the learning began. I had a lot of trouble with frozen drills when I was doing a lot of drilling and was carrying my jack leg up to the machine doctors on surface a few times a week. That went on for a while and it was a major hassle to get it out of the stope, on to a flat car, down to the cage, up to the head frame and then repeat in the opposite direction. Finally my shift boss came down to see what the problem was just as my drill was freezing up again. He took one look at the drill, opened the lubricator and informed me that it was dry....... Well that was embarrassing. Seems the lubricator that I was using in the stope was half the size of the one I had used in the stope school. The one I had learned to drill with that would last all day. (Or at least for the amount of time we were drilling in the school in a day.) What a lesson to learn. Another lesson I learned was to watch your water hoses as the valves could get caught on the ladder the jack leg was pushing against and shut themselves off . . . I learned that lesson with a brand new 16'(?) long steel that I had shoved into a progressively drilled breast hole and proceeded to get it stuck. It, I'm sad to say never survived the blast although someone may have used parts of it as pegs in a wall somewhere. Nice to see your shots all laid out there and to watch the dirt jump and feel the vibrations. Nothing we would get to do underground. Thanks for entertaining us out here in KZbin land. Western British Columbia here on Vancouver Island.

I like to tie my danger noodle, but have added some tape...and often I do use a safety cord... although the only failures I've encountered are down the hole cut offs on my trunk line when loading deep large diameter shear holes, about 80% of the hole would detonate and sometimes leave a few links of presplit in the bottom of the hole leaving cling-ons... we quickly rectified this by adding a 2nd trunk line of det cord with a booster at the bottom initiating both the bottom and the top of the presplit simultaneously... loved the video as usual Dave👏

The only experience I've had with explosives was in the 70s when I worked in Seismic oil search. The shotholes were 50 metres deep and loaded with 2kg of Anzite. When I was on leave, there was a workplace incident in which two shot firers died due to have to treat explosives with respect. A 5 metre deep trench was dug with a dozer and a 2kg tube of Anzite was placed in the bottom and it was refilled. It was sandy country and the resulting bang lifted most of the sand out of the hole.

How / Why does the way the det cord is tied affect the continuation of the 'burn'?

[@demolitiondavedrillandblast]

Ahhh... there is somebody that is thinking. You need to have all of the joints either at right angles like when it is tied or diverging from the source of detonation when taped - think of how the branches of a tree fork out and the source of detonation is at the base of the tree. Either of these is reliable, if you had a taped shot that is fired from the wrong direction you will get a lot of "approach cut off failures" where the detonation shockwave (7000m/s) causes a lot of shrapnel that can cut through the nearby converging cord before the joint is reached.

It would remove the plaster board also! Have used zip ties when it is too wet to use tape.
