影响煤层甲烷储气量的主要因素分析

ANALYSIS ON MAIN FACTORS OF INFLUENCE METHANE RESERVES IN COAL BED

针对煤层的生气量、储气能力、煤层孔隙、割理、裂隙发育、煤层渗透率及其存在环境等影响因素进行了分析， 并对煤层甲烷含量与各影响因素间的关系进行了综述．

Coalbed methane is a kind of clean energy resource and chemical industry raw material, but it is also a hazardous gas for coal mining. The analysis on influencing factors of its reserves will favor the effective utilization of coalbed methane. In this paper, the factors of influence coalbed methane are discussed, which are the capacity of coal seam generating and storage methane, degree of maturation, permeability, cleat system, surface characteristics and existent environment etc., the relation between coalbed methane reserves and every factor have been summarized.
