Comprehansive Auxiliary Technology of Producting 4.6 Mt in Fully-mechanized Coal Caving under Homemade Equipment Condition
From improvement of hoist technology,application of production technology,technological management of mechanical and electrical equipment,this paper introduces some technology measures that secound team of Wangzhuang coal mine produces 4.6Mt in per year,practice provds that fully-mechanized caol caving production comprehansive auxiliary technology is scientific under homemade equipment condition,there are good economic and society performance.
The lake sediments have registered the information of palaeoclimate and palaeoenvironment in the lake itself and the regional scale. This also leads to a complexity in study of the palaeolimnology by all kinds of proxies. How to purify these proxies to indicate the palaeoclimate has become a problem to be solved. Most of the proxies can qualitively identify the percentage of allochthonous and autochthonous organic components, e.g. δ13corg CD/TC. The model introduced in this note has provided a method of quantitatively calculating the amount of allochthonous organic carbon. As for determination of regulating parameters, i.e. A1 and As, further work is still in need.
