摘要:
为了研究深部矿井煤岩体注水对围岩温度场的影响,采用每隔3 m设置一个注水口、低流量中压缓慢注水的方法对煤岩体实施注水降温。基于传热学和渗流力学理论建立了深部矿井热扩散模型,利用Fluent软件进行数值求解,获得了深部矿井煤岩体注水时围岩温度场分布。研究结果表明:矿井在注水时伴随着能量的交换,对于孔隙率超过10%或张性裂隙占主体的矿井中注水降温效果明显;注水速度越大,降温效果越好,当注水速度为1.1 m/s时,围岩体温度降低约为2℃。
Abstract:
In order to study the influence of water injection in the coal and rock mass of deep mine on the temperature field of the surrounding rock, the water injection cooling was implemented in the coal and rock mass by using the method of setting a water injection hole at intervals of 3 m with the slow water injection of low flow and medium pressure. A thermal diffusion model of deep well was established based on the theories of heat transfer and seepage mechanics, and the numerical solution was carried out by using the Fluent software, then the distribution of temperature field when implementing the water injection in the coal and rock mass of deep mine was obtained. The results showed that along with the energy exchange during the water injection of mine, the effect of water injection cooling was obvious for the mine with the porosity of more than 10% or with the tensional fissures as the primary. The larger the water injection speed, the better the cooling effect, and when the water injection speed was 1.1 m/s, the temperature of the surrounding rock body decreased about 2℃.
