摘要
针对煤矿井下采空区岩石冒落形成的多孔隙介质空间的极度不规则性,提出了模糊渗透系数的概念,建立了一种以模糊分析和模糊微分方程为基础的及各种边值为条件的计算采场气体模糊渗流问题的数学模型。该项理论研究成果为预防采空区自然发火提供了有效的途径,对采场内自然发火位置的预测及发火位置控制有较好的理论价值和指导意义。研制了相似模拟模型,针对采空区自然发火问题进行了多项模拟实验,观测并绘制了不同风量下采空区风压等值线及风流分布图;绘制了采空区不同位置漏风情况下风压等值线及风流分布图;绘制了上隅角设置瓦斯排放风筒后采空区风压等值线及风流分布图。
The research picks the multi-hole medium space extreme irregularity in view of the mine pit under which the depletion region rock braves to fall forms, proposed the fuzzy penetration coefficient concept, has established one kind take the fuzzy analysis and the fuzzy differential equation as the foundation and each kind of side value for the condition, computation stope gas fuzzy transfusion question mathematical model. This fundamental research achievement picked the depletion region spontaneous combustion for the prevention to provide the effective way, the spontaneous combustion position forecast and the ignition position control had the good theory value and the guiding sense to the stope in. Has developed the analog simulation model, in view of picked the depletion region spontaneous combustion question to carry on many modelling, observed and draws up under the different amount of wind to pick the depletion region wind pressure equivalent line and the loose distribution map; Drew up has picked the depletion region different position to leak out in the situation the wind pressure equivalent line and the loose distribution map; After drew up on the solid angle establishment gas emissions wind tunnel to pick the depletion region wind pressure equivalent line and the loose distribution map.
