Study on distribution characteristics of trace elements in close range coal seams in Daizhuang coal mine
Abstract：The main object of coal mining is coal seams,so the correlation of coal seams directly or indirectly affects the production safety and economic benefits of coal mine.The first upper 3 coal seam,the upper 3 coal seam and the under 3 coal seam in Daizhuang coal mine are close,and it is not obvious to distinguish.Through the study on the distribution of trace elements in minable seams in Daizhuang coal mine and mastering its rules,we can have a good judgment of different coal seams and effectively avoid the phenomenon of confusing coal seams in mining because of the geological structure factors.Therefore it is significant to design the reasonable mining scheme and progress.Thus it provides scientific basis and guarantee to high efficiency,safety production of Daizhuang Coal Mine.
