Abstract—Leachate from gangue is known as the main pollutants predicted due to release disciplinary and mobilization
source to mining area soil and groundwater pollution. Long term characteristic of leached elements.
leaching experiment are carried out to seek the long term effect
on leachate chemistry of gangue under long term exposure to

rainfall and atmosphere. Gangue from Xishan coal mine is used
for long term dynamic leachate to analyze pare the Grinded gangue samples collected from Xishan mining
changes of the various metal ions in leachate in different water areas in Taiyuan city, Shanxi province, are about - mm in
supply conditions. The results show the obvious changes of the size. The coal-bearing strata of this mine area are Taiyuan
component during the first week of the experiment, and the group of Carboniferous and Shanxi group of Permian. The
release rate and amount of ponents are much lower experiment instrument is self-designed (fig. 1). The height of
under the conditions of continuous leaching. With the increasing grinded gangue is 40cm i
