“I would recommend the Buxplug, to other minesites, as a better method of plugging”

Prior method of plugging was rags.

“ensures that there is a good seal at the base of the hole, no need to check later on the stuffing, etc.”
“reduces the likelihood of grout from exiting the hole – maintains better grout pressure within the hole and enables “fuller” encapsulation.”
“you put it up the hole, along with the tubes and bolt and then it’s done – you don’t have to keep checking that there is a seal so the grout does not escape”

STRATA CONTROL ENGINEER (UG COAL MINE, NORTH QUEENSLAND)
Prior method of plugging was cotton wadding.

“Awesome, the only way to go, they are lot easier, faster and tidier than using cotton waste and cement slurry.”
He also said that he uses insulation tape to secure the Buxplug onto the cable bolt for easier installation.

“The results of the tests were as expected because the pre-tensioning cycle was improved by 95%. It used to take 48 hours to pretension at 5 tons, with the special cement, but with the addition of the Buxplug it was done in 2,5 hours, and at 10 tons…..with the success of these tests it very likely that its use will become more popular in Chile”
