Canopy Air Curtain

Abstract Blasters are one of the highest exposed work groups to diesel particulate matter (DPM) in underground metal/nonmetal mining. These workers can spend a good portion of their day under a canopy in a basket loading blastholes with explosives. Therefore, one way of potentially reducing their exposures to DPM is to place a canopy air curtain (CAC) on the basket of the ANFO loader. In the original design of the CAC on a roof bolting machine and shuttle car, a fan draws in air through a filter to capture the dust and then supplies clean air beneath the canopy where a miner is working. This paper describes the testing of a CAC that was redesigned to fit an ANFO loader and prevent exposures to DPM as well as respirable dust. Laboratory measurements demonstrated reductions of submicron particles that relate to the percent reductions of DPM. The CAC provided substantial protection of mine workers to DPM (80% reductions), from within 15.24 cm (6 inches) of the edge of the CAC using a 7.62-cm (3-inch) lip. As the mine worker approaches the edges of the CAC, the percent reduction starts to reduce to the 30–50% range. The mine worker achieves the best results when within 15.24 cm (6 inches) from the edge of the CAC. In addition, the CAC should be located such that the breathing zone of the mine worker is 25.4–50.8 cm (10–20 inches) below the CAC.

The World

Hydraulic fracturing emerges currently, all over the world, as one of the more strategic techniques used by companies in the oil exploitation sector. This technique is characterized by its high productivity and profit in relation to conventional methods of hydrocarbon exploitation. However, in many countries, as is the case of Brazil, there are several divergences considering the employment of this methodology. Many renowned researchers attest that there are several irreversible environmental impacts generated by the use of this methodology. Among the main environmental impacts are the risk of groundwater level contamination, the risk of surface subsidence, and the risk of the environment contamination with fluids used in the process of the oil and gas extraction.
