In the mining world, every step is a challenge, especially when it comes to wet holes at blasting sites. Airdeck methods, often using gas bags and similar methods, are considered ineffective in wet holes. However, the advent of revolutionary airdeck technology from MTi GROUP, BLASTBAG™, has changed this paradigm. We offer a solution to this problem, ensuring optimal airdeck performance in wet holes.

BLASTBAG™ Performance in Wet Holes

Air decking is a blasting technique that creates an air space within the blast hole. This empty space can be utilized to reduce the length of the fill column/powder factor, which aims to reduce explosives costs, flyrock, ground vibration, and so on. The air deck can be positioned on the top deck, middle deck, or bottom deck.

However, there’s often a perception that the use of air deck techniques using blast bags like BLASTBAG™ is suboptimal and poses challenges in wet hole applications. Now, we’re offering a solution to this problem, ensuring optimal wet hole air decking.

MTi Group’s BLASTBAG™ is an air deck technology that not only performs well in dry holes but also in wet or wet blastholes. BLASTBAG™’s performance in wet holes has been proven.

The application of BLASTBAG™ has been tested in holes with 80% water content, positioned on the free face, and demonstrated excellent results, as seen in the image below of BLASTBAG™ application in a wet hole.

The use of BLASTBAG™ in wet holes, particularly on the free face, still helps distribute blasting energy effectively toward the free face, even with reduced explosive content, particularly for use in wet holes.

The application of BLASTBAG™ in wet holes requires readily available and easily controlled tools, along with adjustable inflation speed. In addition to applying BLASTBAG™ to wet holes, BLASTBAG™ can also withstand dynamic water flow in the hole, due to its exceptional strength when compressed in the hole when fully expanded.

BLASTBAG™ technology offers efficiency in the mining industry, particularly in blasting, with a focus on optimizing time and resources. BLASTBAG™ is designed to deliver consistent blasting results without compromising safety, while also delivering optimal results.

Leave behind the old paradigm of suboptimal air deck applications in the form of air bags in wet holes. BLASTBAG™ MTi GROUP opens the door to a future of smarter, safer, and more efficient mine blasting. Let’s move towards the future of mine blasting together with BLASTBAG™ MTi GROUP!
