The Environmental Impacts Of Coal

Coal is the dirtiest of all fuels.From mining to coal cleaning, from transportation to electricity generation to disposal, coal releases numerous toxic pollutants into the air, water and land.These disrupt ecosystems and endanger human health.Some cause cancer, others damage the nervous and immune systems, and some impede reproduction and development.

We are a mining equipment production and sales company, with three production bases and four research institutes, more than 600 production equipment, precision production, and service globally.
