Blast-induced noise and ground vibrations are two of the most signi cant challenges in blast rock fragmentation, and they can have an impact on mine stability and the safety of personnel and machines nearby. As a result, evaluating the slope stability and the contribution of powder factor on ground vibration and noise induced by blasting in small scale mines plays an important role in improving mine sustainability. The results of slope stability assessment and the effect of explosive charge on blast induced ground vibration and noise level at selected carbonate rock quarries in Akoko Edo, Nigeria are presented in this paper. The purpose of this research is to examine the slope stability of a mine using kinematic analysis and slope mass rating techniques, as well as to determine the relationship between powder factor and ground vibration and noise caused by blasting. According to the study results, the average blast induced noise and ground vibration from the nine blast rounds are 123-151 Kb and 2.43 mm/s to 5.03 mm/s, respectively. According to the ndings, the powder factor has a positive relationship with blast-induced ground vibration and noise level. The ndings also show that the results of SMR and kinematic slope analysis techniques are similar with less variation and can be used to assess slope stability in practice.

Blasting powder factor is an important consideration when planning a drilling and blasting operation because it affects both the total production cost and the efficiency of downstream operations. Ten production blasts and 38 blast record datasets from a small scale dolomite quarry in Akoko Edo, Nigeria were studied to determine the effect of powder factor on blast fragmentation size distribution and uniformity index. This research evaluated the relationship between powder factor and fragmentation size distribution, as well as apply artificial neural network to model small diameter drill hole blast powder factor based on predominant controllable blast design factors. According to the research, the small scale blasting powder factor ranges between 0.6 and 1.0 kg/m3. According to the WipFrag analysis, increasing the powder factor causes an increase in the fragmentation mean size and an upward shift in the particle size distribution curve. The mine blasting operation uniformity index was also found to be between 1.3 and 1.68. The powder factor range of 0.7-0.9kg/m3 was determined by the uniformity index. The performance of the proposed ANN model was evaluated using the correlation coefficient and found to have a high prediction accuracy (R2 = 0.997). As a result, the proposed ANN models can be used to improve the blast powder factor for real-world applications.
