Geochemistry characteristics and sedimentary micro-environments of No.11 coal seam of the Taiyuan Formation of Upper Carboniferous in Pingshuo Mining District,Shanxi Province;

Pingshuo: the Green Ecological Industrial Park Construction

By using three-element phase diagram of SiO2-Al2O3-CaO,the change of slagging tendency of blended coal after blending Yulin Coal and Pingshuo coal has been analysed,and result of analysis by using the three-element phase diagram being verified by adopting test method of the fallout furnace.

By using some examples, this paper analyzes the main problems existing in the contract management of the modern enterprise, probes into the origins of these problems, and starting from the practice of Pingshuo Company, expounds the application of the contract management under the conditions of the market economy, and sums up some improving methods.

In the Shuoxian plain,substantive depositional environment researches have carried out since reconnaissance stage,thus promoted correlation of splitting Nos.
