What is an opencast mine for the digging-out of stone?
An opencast mine, also known as an open-pit or open-cut mine, is a type of surface mining where minerals, particularly stone and ores, are extracted from a large excavation in the ground. This method involves removing overburden (the soil and rock overlaying the mineral deposit) to access the desired materials. Opencast mining is typically used for resources that are located close to the surface, allowing for efficient extraction but often resulting in significant landscape alteration and environmental impact. It is commonly employed for materials such as coal, limestone, and various types of rock used in construction.

How is air borne dust survey conducted in opencast mine?
Airborne dust surveys in opencast mines are typically conducted by placing dust samplers at strategic locations around the mine site to collect airborne particles. These samplers are then analyzed to determine the concentration and composition of the dust particles present in the air. This data is used to assess the effectiveness of dust control measures and to ensure that exposure levels are within acceptable limits for worker safety and environmental regulations.
Where a coal mine is found?
