In the world of blasting in mining areas, it’s possible to produce large, oversized chunks of rock, better known as boulders. Any large chunk of rock produced by blasting that cannot be adequately handled by standard digging and loading equipment used in mining operations is called a boulder. To prevent these boulders from disrupting productivity and damaging the digging and loading equipment, secondary blasting must be performed if manual rock breakers are not feasible.

Secondary blasting is the process of blasting to reduce the size of rock chunks. Secondary blasting is performed when there are chunks of rock with insufficient fragmentation, and when there are chunks of rock that interfere with the continuity of mining production. Generally, in the secondary blasting process, the rock to be blasted is covered with geotextile to prevent flyrock and reduce airblast. However, in reality, geotextiles often tear and are unable to withstand the blasting energy, resulting in flyrock and airblast.

MTi GROUP’s BLASTBAG™ boasts exceptional capabilities, offering the strength to withstand blasting energy. BLASTBAG™ can be used as a hole cover (replacing stemming) in secondary blasting, eliminating the need for geotextiles to cover the rock. By using MTi GROUP’s extremely strong BLASTBAG™, which expands completely in the hole, BLASTBAG™ can withstand blasting energy with confinement, maximizing the blasting energy to break up the rock and reducing the distance between flyrock and airblast. Without the need for geotextiles, BLASTBAG™ can now be a solution for secondary blasting. As shown in the image below.

MTi GROUP’s BLASTBAG™ technology brings efficiency to the world of mine blasting, focusing on optimizing time and resources. BLASTBAG™ is designed to deliver consistent blasting results without compromising safety, and delivers results according to your expectations.
