Answer to Question #197626 in English for Coral

Question

identify three main technological innovations and discuss their effects on the impact of small-scale mining on the environment.

Answer 1

a.1.Automation 2.Electrification3. Renewable resources

b. 1. Automation ;being the creation of technologies to produce and deliver goods and services with minimal human intervention, this reduces job opportunities, use machines causes noise pollution, land degradation and sometimes some machines may not be suitable for relatively small mineral deposits. However automation help in producing high quality goods within a short period and increases efficiency and ensures safety compared to previous mining methods

2. Electrification; fossil fuel use at mining sites is a significant operation cost and source of both local particulate matter and air pollution. At mining operations connected to electricity grids, large trucks generally run on diesel which release substantial emissions into air causing air pollution. Electrification causes contamination of ground and ground water bodies. However use of electricity in mining is somehow environmental friendly compared to other methods hence reduce levels of land and air pollution.

3. Renewable resources; use of renewable resources in mining reduces both land and air pollution and saves cost of mining as they are readily recycled.
