ABSTRACT

The distribution of permeability due to stress-strain changes in the gob region affects the air and heat distribution, forming spontaneous combustion (sponcom). The main question here is how the fluent flow model changes under changing conditions such as permeability. For this purpose, a geomechanical model based on a numerical analysis was used to determine permeability distribution. Thus, a significant advantage was provided to develop sponcom forecasting models over conventional ventilation measurements.

煤矿井下采空区结构渗透率变化防自燃研究

摘要

由于采空区应力应变变化引起的渗透率分布影响空气和热量分布，形成自燃（sponcom）。这里的主要问题是流动模型在渗透率等变化条件下如何变化。为此，使用基于数值分析的地质力学模型来确定渗透率分布。因此，与传统通风测量相比，开发 sponcom 预测模型具有显着优势。
