This paper analyzes the gathering coal environment in Pingzhuang Coal-field,finds out a few gathering coal laws.

On the basis of the analysis results of the trace elements of coals in the Taiyuan Formation from Zaozhuang coal field with INAA(Instrumental Neutron Activation Analysis),the trace element distributions,fraction mass,coefficient and cluster diagram are obtained.

"Non-coal zone" , a zone or strip with coal seam getting thinner and unminable ,is a structure peculiarly in Kangping Coal Mine.

Based on geological exploration and mining data in the Kaiping coalfield,combined with studied results of the predecessors,systematically analyzed structural distribution and combination features in the area.

Based on the elemental, maceral, micro-fracture, coal facies, liquid nitrogen adsorption/desorption and mercury injection analyses, the coalbed methane (CBM) geological characteristics, coal reservoir physical characteristics, CBM resources and its exploration and exploitation prospect in Pingdingshan coalfield were systematically studied.

it is discovered that Guodishan fault in Pingdingshan coalfield is a syndepositional inheritable coal-control fault- It was active during coal-forming period.

Tianzhuang is a kind of production organization which has big estate ownership as its foundation and body-compelled extra-economic labor rent charge or real object rent charge as its exploit form, managed by landlord in Han Dynasty.
