Application Of Coal Logging Curve Comprehensive Comparison In The Exploration Of Zi Chang Mining Area

Geophysical well logging was one of the main components of Geophysics,and it had a very strong applicability in industry.In oil exploration,coal field exploration,uranium exploration and partial metal ore exploration,geophysical well logging is one of the indispensable means.In this paper,we mainly discussed the curve contrast analysis of coalfield well logging,and made a comprehensive comparative study in the Zi Chang mining area.At first,this paper introduced the concept and principle of coal logging.It can not only qualitative identify the coal seam,but also be quantitative interpretation of coal seam depth,seam thickness,coal gangue thickness and other core data.Then,this paper introduced the principle of the comparative analysis of the log curve in the coal field,on the basis of introducing the principles and characteristics of several parameters of coal field logging.This paper studied the Zi Chang mining exploration of coal production as an example.The exploration area of multiple single hole logging curves together was analyzed,and the curve shape of the rules of the reaction was summarized,in order to explain the purpose of geological problems.Finally,the feasibility and superiority of the coalfield logging contrast technology was verified.
