    The particulate pollution in the openpit coal mines of China is particularly severe in winter. The aim of this study is to understand the pollution characteristics of particulate matter (PM) in winter and provide a basis for the prevention and control of particulate pollution. We took the problem of PM concentration at the bottom of the Haerwusu Openpit Coal Mine (HOCM) as the research object.

The surface operations began in 1972. The current operator has been mining on the property since 2004. Open pit geometry is based on highwalls (pit slopes

    Fushun transforms centuryold coal mine into tourist site

     · The West Pit once the largest openpit coal mine in Asia served as an economic engine for Fushun City northeastern China s Liaoning Province. It fueled China s heavy industries beginning in 1914 and peaking in the early 1960s with annual coal production reaching 18 million tons. However prosperity came at a price.

    Phase Planning for Open Pit Coal Mines through Nested Pit

     · This paper presents a phase planning method specially designed for coal deposits with nearly horizontal bedded coal seams. The geology of this type of deposit is modeled into a column model instead of a block model to avoid coalrock mixing in blocks. A nested pit generation algorithm is developed for producing a series of nested leaststrip ratio pits with a column model as its input.
