摘要

煤的微孔和净网是流体渗流的主要渗透性来源。在不同的总应力和不同的环境条件下,流体的流动行为进行了现场和实验室试验。根据测量结果,将开发一个多尺度、两相流模型来描述和量化矿山作业的各种影响,重点是将基于点的结果从小尺度外推到区域尺度的挑战。

In-situ and laboratory measurements of coal matrix and cleat permeability
Micropores and the cleat network of coal provide the principal source of permeability for fluid flow. The flow behavior of fluids under varying total stress and different environmental conditions are examined in field and laboratory experiments. Based on the measurements a multi-scale, two-phase flow model to describe and quantify the various effects of the mine operation will be developed with a focus on the challenge of extrapolating point based results from a small scale to a regional scale.
