【摘要】：為了能夠準(zhǔn)確掌握礦井巷道在一個完整通風(fēng)周期內(nèi)的圍巖的溫度變化情況并以此為基礎(chǔ)對其進(jìn)行經(jīng)濟(jì)性評價研究;首先以傅里葉導(dǎo)熱定律為基礎(chǔ),采用Abaqus軟件建立數(shù)值模型并利用有限元方法對巷道圍巖與空氣熱交換過程以及巷道內(nèi)部的圍巖溫度分布進(jìn)行了求解研究,獲得了巷道圍巖對冷、熱量的存儲量大小及存儲規(guī)律;之后利用等效空調(diào)方法對巷道圍巖調(diào)熱能力進(jìn)行了經(jīng)濟(jì)性評價。結(jié)果表明:礦井圍巖調(diào)熱圈具有較大的經(jīng)濟(jì)優(yōu)勢,未來可以進(jìn)一步嘗試進(jìn)行工程實(shí)踐。
[Abstract]:In order to accurately understand the temperature change of surrounding rock in a complete ventilation period of mine roadway and to evaluate its economy on the basis of it, firstly, based on Fourier's law of heat conduction, The numerical model is established by using Abaqus software, and the heat exchange process between surrounding rock and air and the temperature distribution of surrounding rock in roadway are solved by using finite element method, and the storage amount and storage law of cold and heat in surrounding rock of roadway are obtained. The economic evaluation of the heat regulating capacity of surrounding rock of roadway is carried out by using the equivalent air conditioning method. The results show that the heat regulating circle of surrounding rock of mine has great economic advantages and can be further tried in engineering practice in the future.
