Abstract

Coal mining activities in Vietnam, on the one hand bring economic efficiency, also cause environmental impacts, especially dust, noise, emissions and wastewater. The article used the method of collecting, analyzing, synthesizing documents, the method of field investigation, the method of sampling analysis and data processing to assess the current state of the environment at Khanh Hoa Coal Company. The research results have shown that environmental pollution has been minimized by dust and wastewater treatment technology. The quality of the air environment (mining area, surrounding) and the water environment (production wastewater, domestic wastewater, groundwater, surface water) of the company at the monitoring time all ensure the coresponding national technical regulations. This is the basis for Khanh Hoa Coal Company to continue synchronous control measures to develop production activities and meet regional environmental protection requirements.
