Abstract
Today's mining industry still needs mining blasting to grow and provide enough raw minerals for various industrial uses. It is essential to identify the blasting and explosion stages. Using stemming plugs in blast holes will directly influence rock fractures, ground vibration, air blast, noise, fly rock, dust, and fume. This study aimed to explore the viability of using natural rubber latex to improve blast-stemming efficiency. Testing was done at the feldspar mine in Nakhon Si Thammarat province, Thailand. The performance was evaluated using rock image software to compare the distribution of rock sizes. In conclusion, the preliminary investigation revealed that blasting latex-filled holes with conventional blasting procedures at d20, d50, and d80. The rock achieved size distribution values of d20, d50, and d80, with conventional methods at 2.31, 6.24, and 12.60 inches, respectively. While using natural rubber latex was found in d20, d50, and d80 at 2.05, 5.68, and 10.63 inches, which proportionally represented a lesser proportion of 11%, 9%, and 16% of the average size. It also found that the oversize was less than typical, with lower ground vibration and fly rock.
