摘要: 利用多孔介质中的渗流理论,建立了综放采空区流场流动数学模型,以山西晋城王台铺煤矿2304工作面为例,应用FLUENT软件对其采空区流场进行了数值模拟,得到氧浓度分布与速度分布,并将氧浓度分布图与速度分布图进行透明迭加,取公共部分,即得到自燃氧化带。同时在2304工作面开展采空区“三带”的范围观测,验证了数值模拟结果及所建立的数学模型正确,对矿井防灭火工作具有指导作用。
关键词: 采空区, 三带, 数值模拟, 氧浓度分布
Abstract: Flow mathematical model of fully mechanized minedout area flow field was set up by using seepage theory in porous media, take 2304 working face of Wangtaipu coal mine at Jincheng of Shanxi province as the example,numerical simulation was done on its minedout area flow field using FLUENT software, distribution of oxygen density and velocity were obtained, oxygen concentration distributing graph was clear overlapped with velocity profile,pick public sector, spontaneous combustion oxidation zone was obtained. Meanwhile, scope observation of "three zones" of minedout area was carried out on 2304 working face. Numerical simulation result was verified by the scope doservation, and it proved established mathematilal model is correct, simulation results provide guidence for fireprevention and firefighting work of mine.
Key words: Minedout area, Three zones, Numerical simulation, Distribution of oxygen density
