摘要:
为开展矿井热害防治的实验教学，设计并搭建周期性风温作用下巷道非均质围岩换热实验装置，能直观展示高温围岩各岩层的温度变化。利用实验数据可计算出巷道壁面热流密度，进而定量估算巷道围岩的散热量。结果表明：周期性风温通过后，模拟巷道围岩体各处温度随时间也呈简谐波变化；对于非均质的围岩体，导热系数越大的岩层，周期性风温的调热能力越强；巷道壁面处的热流密度也呈周期性变化，但围岩体总体表现为散热，且散热量随时间快速减小，并最终稳定在1.3×104 kJ/m2。
Abstract:
In order to carry out the experimental teaching on the prevention and control of thermal hazard in mine,an experimental device for the heat exchange in the non-homogeneous surrounding rock of the roadway under the action of periodic wind temperature was designed and built,which could visually demonstrated the temperature change of each rock layer in the high-temperature surrounding rock.The experimental data could be used to calculate the heat flow density at the wall surface of roadway,and then quantitatively estimate the heat dissipation of the roadway surrounding rock.The results showed that after the periodic wind temperature passed through,the temperature at each part of the roadway surrounding rock body also changed over time in simple harmonic wave.For the non-homogeneous surrounding rock body,the larger the thermal conductivity of the rock layer,the stronger the thermal regulation ability of the periodic wind temperature.The heat flow density at the wall surface of roadway also changed periodically,but the surrounding rock body presented the heat dissipation in general,and the heat dissipation decreased rapidly with time and finally stabilized at 1.3×104 kJ/m2.
