Relation of pore distribution of coal with water infusion increment in seams
Journal of China Coal Society(2000)
Abstract
Based on the characteristic analysis and laboratory test on coal samples taken from different seams, the minimum coal pores for water permeating into and maintaining in them is determined which have the size from 0 07 μm to 0 22 μm and 0 14 μm on average, a new concept of linked porosity is put forward and the relation of the linked porosity with water infusion increment in seams is derived, which have actual guiding significance for infusion in coal seams.
