高抽巷空间层位参数不仅影响采空区瓦斯的抽放效果，而且影响采空区漏风流场以及采空区自燃三带的分布规律。论文以矿井防灭火及采空区自燃三带识别等知识为理论依据，应用流体力学软件 FLU-ENT分别模拟研究了高抽巷空间层位的不同垂距和平距两种参数对采空区漏风流场及采空区自燃三带分布规律的影响。模拟研究结果表明：采空区氧化升温带的宽度随高抽巷垂距参数的逐渐增大而增大，随高抽巷平距参数的变化而呈现出先减小后增大的变化趋势。通过本文的模拟研究，为合理优化高抽巷空间层位参数提供了一定的方法和手段，使高瓦斯矿井在安全高效生产过程中最大程度地兼顾防灭火和防瓦斯两方面的技术要求，从而保障矿井安全生产。

High drainage roadway horizon parameters not only influence gob drainage effect ,but also have effect on the gob air leakage field and gob spontaneous combustion three zones ’ distribution .This paper makes mine fire-prevention and gob spontaneous combustion three zones recognition as theoretical basis , applies fluid mechanics software FLUENT respectively to stimulate the distribution law of gob air leakage field and gob spontaneous combustion three zones with different vertical and horizontal distances .Stimula-ted results show that the width of gob oxidization and heat accumulation zone increase with the high drain -age roadway vertically ,descend initially and then rise with the horizontally .Through stimulation study ,it supplies a certain method to reasonablely optimizatate high drainage roadway horizon parameters ,which to a great extent ensures mine safety production , consideration to the fire and gas prevention technical re-quirements during the safety and effective production.
