Research on optimization of layout method of cooling system on coal face

  • 摘要: 针对长距离矿井采煤工作面存在热害严重、局部高温及温度分布不均匀等问题,以某矿采煤工作面为研究背景,在对该矿热源进行分析的基础上,提出了一种工作面冷量分流的降温布置方式,即在冷量不变的情况下,将空冷器安装于进风巷内,同时匹配1台通风机,通风机与空冷器通过风筒进行连接,利用风筒将部分冷量直接输送至工作面,以起到降温的作用。通过运用CFD软件建立三维模型,分别对常规降温布置和冷量分流布置2种布置方式进行数值模拟,结果表明,采用冷量分流布置方式后,温度场分布更匀称,低温区域面积更广,能有效改善工作面的降温效果。
    Abstract: In view of problems of serious thermal damage, local high temperature and uneven temperature distribution of long-distance coal face, on the basis of analysis of heat source on the coal face of a coal mine, a layout method of cooling quantity shunting was proposed. That is, under the condition of constant cooling quantity, the air cooler is installed in intake airflow roadway, and one ventilator is matched at the same time. The ventilator is connected with the air cooler through air duct, and part of the cooling quantity is directly transferred to the coal face by the air duct to play the role of cooling. CFD software is used to establish three-dimensional models, and the two layout methods of conventional cooling layout and cooling quantity shunting are numerically simulated respectively. The simulation results show that the distribution of the temperature field is more uniform, and the low temperature area is wider after using the layout method of cooling capacity shunting, which can effectively improve the cooling effect of coal face.
