阜康矿区煤的孔隙与裂隙特征
Characteristics of the pore and fracture in Fukang mining area
摘要
Abstract
The pore and fracture of coal are the deposit space and channels used for migration and output of coal-bed methane. In this paper, we studied the characteristics of pore and fracture and evaluated occurrence character-istics and permeability of coalbed methane in Fukang mining area through the methods of macroscopic and micro-scopic analysis of coal and rock, mercury injection and pore structure analysis of coal. The results show that the micro-pore of Fukang mining area is large and it is conducive to the adsorption and desorption of coalbed methane. Fracture development has the character of heterogeneity that the fracture in the west of Fukang mining area is the most developed, followed by the east, not developed in the center. Vitrinite increase results the increment of small and micro pores of coal, and it is conductive to absorption of CBM. The porosity is controlled by mesopore volume. The porosity of coal in Fukang mining area tends to increase with vitrinite reflectance. The results have some the-oretical significance for the exploration and development of coalbed methane in Fukang mining area.关键词
