Nigeria's abundant solid minerals constitute some of the largest known deposits in recent years under different categories. With the activities in the sector characterized by production and a growing environmental decline often overlooked. This research uses a mix scale approach of descriptive statistics and GIS methodology in analyzing the ecological impacts of mining in Nigeria.
2. Water effects on blasting performance. Ineffective blasting performances due to the watery borehole negatively influence the productivity of mines by causing poor fragmentation, poor level cut, back-break, and blasthole blow-up. They also increase the environmental and safety risks resulting in the excessive vibration, fly rock, and toxic fumes.
