In conventional blasting, much of the blasting energy is lost and the optimal fragmentation size is not achieved. Large fragmentation can reduce the loading and unloading efficiency of mining equipment. According to Melnikov and Marchenko (1971), an air gap in the explosive column helps distribute the blasting energy throughout the rock mass. This significantly reduces blasting costs by 10% to 30% while maintaining good fragmentation.
One mining accessory that can create an air gap in blastholes is a gas bag, also known as BLASTBAG™. BLASTBAG™ itself is an inflated gas bag that can be used for air decking, sealing holes, or dispelling water at the bottom of holes of any depth. The BLASTBAG™ from MTi Group differs from other gas bags in that it has an aerosol can equipped with a two-speed inflation mechanism that allows for fast or slow inflation. Aerosol cans with a trigger that is very easy to press and only uses one hand, the gas produced is safe for the surrounding environment and does not have a negative impact on the blasting process, and has a hang tag on both sides that makes it easy to apply on the middle deck. The shape of the aerosol can from BLASTBAG™ can be seen in the image below.
Furthermore, BLASTBAG™ differentiates itself from similar products in that the air gap formed in the blast hole is perfectly integrated, providing a high level of precision in the air gap height. The difference between BLASTBAG™ and similar products is particularly evident when it comes to efficiency. BLASTBAG™ is no ordinary product; it is a breakthrough that has captured the attention of many mining industry experts.
BLASTBAG™ can also be used for stemming due to its powerful ability to lock blasting energy and gases out of the hole. This utilized blasting energy is more efficient in breaking hard rock. MTi Group’s BLASTBAG™ can provide cost savings without compromising blasting results.
We will further discuss the advantages of BLASTBAG™ compared to similar products from a technical, economic, and environmental perspective. This way, you can make an informed decision when choosing a solution for your mine blasting project.
So, if you’re looking for more than just a standard product, if you want cost-effective blasting, then MTi Group’s BLASTBAG™ is the answer to your modern mine blasting needs. Discover the difference. Discover efficiency. Discover the future in every blast with BLASTBAG™.
