In order to control the dust pollution problem of coal mine transportation roadway, the geometric model of Qipanjing coal mine transportation north roadway was established according to the ratio of 1∶1 by using numerical simulation software. Firstly, based on the standard k-ε turbulence model and particle tracking model, the airflow-dust coupling characteristics of the transportation roadway were studied, and a multi-section spray dust reduction technology for simultaneously controlling the transfer point and the transportation roadway was proposed according to its characteristics. Then, the effectiveness of the new dust reduction technology was verified by the combination of numerical simulation and experiment. Finally, the field application was carried out in the north roadway of the transport roadway in Qipanjing Coal Mine to verify the practicability and high dust reduction characteristics of the technology. The results show that the airflow distribution in the transportation roadway is affected by the running speed of the belt and the traction force to produce the induced airflow. The overall average airflow velocity is about 0.6 m/s, and the dust particles are dispersed by the airflow of the roadway. The dust with a particle size of less than 25 μm is suspended at the sidewalk, while the dust with a particle size of more than 25 μm is deposited on the surface of the belt and the floor of the roadway. The new dust reduction technology realizes the perfect coverage of the transfer point, and a supersonic fog curtain is formed in the main roadway to intercept and capture the dust that escaped from the transfer point. The test results show that the supersonic spray has a large range of fog curtain, strong wind resistance and significant continuous dust reduction effect. Through the field application of the north roadway of the transport roadway in Qipanjing Coal Mine, the highest dust reduction efficiency of total dust and respirable dust reached 80.12% and 83.15% respectively.

为了治理煤矿运输巷粉尘污染问题,利用数值仿真软件,按照1∶1的比例建立棋盘井煤矿运输巷北大巷几何模型。首先,基于标准k-ε湍流模型和粒子追踪模型,展开运输巷风流-粉尘耦合特征研究,并根据其特征提出同时治理转载点和运输巷的多断面喷雾降尘技术;然后,通过数值仿真与试验相结合的方法,验证新型降尘技术的有效性;最后,在棋盘井煤矿运输巷北大巷开展现场应用,验证该技术的实用性及高降尘特性。结果表明:运输巷内风流分布受胶带运转速度及牵引力影响产生诱导风流,整体平均风流速度约为0.6 m/s,而粉尘粒子受巷道风流裹挟扩散,粒径为25 μm以下的粉尘悬浮在人行道处,而粒径为25 μm以上的粉尘沉积在胶带表面和巷道底板上;新降尘技术可实现对转载点的完美覆盖,且主巷道内形成1道超音速雾幕,拦截并捕集转载点逃逸的粉尘。超音速喷雾的雾幕范围大,抗风性强,持续降尘效果显著。经棋盘井煤矿运输巷北大巷现场应用,全尘和呼尘的最高降尘效率分别达到80.12%和83.15%,验证了文中所提降尘技术的有效性。

为了治理煤矿运输巷粉尘污染问题,利用数值仿真软件,按照1∶1的比例建立棋盘井煤矿运输巷北大巷几何模型。首先,基于标准k-ε湍流模型和粒子追踪模型,展开运输巷风流-粉尘耦合特征研究,并根据其特征提出同时治理转载点和运输巷的多断面喷雾降尘技术;然后,通过数值仿真与试验相结合的方法,验证新型降尘技术的有效性;最后,在棋盘井煤矿运输巷北大巷开展现场应用,验证该技术的实用性及高降尘特性。结果表明:运输巷内风流分布受胶带运转速度及牵引力影响产生诱导风流,整体平均风流速度约为0.6 m/s,而粉尘粒子受巷道风流裹挟扩散,粒径为25 μm以下的粉尘悬浮在人行道处,而粒径为25 μm以上的粉尘沉积在胶带表面和巷道底板上;新降尘技术可实现对转载点的完美覆盖,且主巷道内形成1道超音速雾幕,拦截并捕集转载点逃逸的粉尘。超音速喷雾的雾幕范围大,抗风性强,持续降尘效果显著。经棋盘井煤矿运输巷北大巷现场应用,全尘和呼尘的最高降尘效率分别达到80.12%和83.15%,验证了文中所提降尘技术的有效性。

In order to control the dust pollution problem of coal mine transportation roadway, the geometric model of Qipanjing coal mine transportation north roadway was established according to the ratio of 1∶1 by using numerical simulation software. Firstly, based on the standard k-ε turbulence model and particle tracking model, the airflow-dust coupling characteristics of the transportation roadway were studied, and a multi-section spray dust reduction technology for simultaneously controlling the transfer point and the transportation roadway was proposed according to its characteristics. Then, the effectiveness of the new dust reduction technology was verified by the combination of numerical simulation and experiment. Finally, the field application was carried out in the north roadway of the transport roadway in Qipanjing Coal Mine to verify the practicability and high dust reduction characteristics of the technology. The results show that the airflow distribution in the transportation roadway is affected by the running speed of the belt and the traction force to produce the induced airflow. The overall average airflow velocity is about 0.6 m/s, and the dust particles are dispersed by the airflow of the roadway. The dust with a particle size of less than 25 μm is suspended at the sidewalk, while the dust with a particle size of more than 25 μm is deposited on the surface of the belt and the floor of the roadway. The new dust reduction technology realizes the perfect coverage of the transfer point, and a supersonic fog curtain is formed in the main roadway to intercept and capture the dust that escaped from the transfer point. The test results show that the supersonic spray has a large range of fog curtain, strong wind resistance and significant continuous dust reduction effect. Through the field application of the north roadway of the transport roadway in Qipanjing Coal Mine, the highest dust reduction efficiency of total dust and respirable dust reached 80.12% and 83.15% respectively.
