This dataset describes the open-pit mining of raw coal, with the following process steps: Drilling: Holes are drilled on the mining face of the mining area according to the distribution of the ore body and mining design, typically using large drills. The main purpose of drilling is to prepare channels for blasting operations. Blasting: Blasting is the process of filling drilled holes with explosives and detonating them to break the ore or rock. The resulting碎 stones provide convenience for subsequent loading operations. Loading: Large excavation equipment (such as electric shovels or hydraulic excavators) is used to load the blasted ore or rock onto transportation equipment. The choice of loading equipment generally depends on the size of the ore body and geological conditions. Crushing: The ore or rock is initially crushed to facilitate subsequent transportation or further processing. Crushing typically occurs at the mining site or a temporary crushing station and aims to reduce the size of the ore to improve transportation efficiency. Transportation: Transportation refers to the process of moving the ore or waste rock from the mining site to a designated location, typically using large trucks, conveyor belts, or railways. The selection of transportation routes and equipment depends on the scale of the mine and transportation distance. Dumping: Dumping is the process of transporting overburden, waste rock, or other non-mineral materials to the waste dump. The dump is usually located around the mine, taking into account stability and environmental impact. Pollutant Treatment and Disposal: Waste, dust, wastewater, and other pollutants generated during open-pit mining need to be treated. Dust is typically controlled through spraying water for dust suppression, and wastewater is treated through sedimentation ponds and chemical processes before discharge to ensure compliance with environmental standards. Ecological Restoration and Remediation: The environmental damage caused by mining needs to be mitigated through ecological restoration measures, including topsoil reclamation, vegetation restoration, and soil and water conservation. The goal of ecological restoration is to restore the natural ecosystem of the mined area and reduce the long-term impact on the surrounding environment.

The raw coal referred in this dataset is the coal that has only had visible gangue selected out after mining, without undergoing any processing. Raw coal is a crucial link in the global energy supply chain, widely used in power generation, steel production, and industrial manufacturing.
