摘要
为充分了解井下综采工作面内的湿度场,以平煤天安一矿31070综采工作面为原型,采用COMSOL Multiphysics数值模拟软件对综采工作面内的空气流动、湿度分布进行模拟研究,并实测现场湿度。结果表明:综采工作面湿度场内湿度最大区域位于采煤机附近(相对湿度值接近98%),采煤机后方贴近壁面处存在绸带状的高湿区域,出风口位置湿度场数值高于进风口位置;井下现场实测对比验证显示,模拟湿度值与实测湿度值的整体偏差在1. 8%以内,数值模拟方法准确可靠,可用于井下综采工作面湿度场分布规律的研究。
In order to fully understand the humidity field in the underground fully-mechanized mining face,this paper USES COMSOL Multiphysics numerical simulation software to simulate the air flow and humidity distribution in the fully-mechanized mining face,and makes a comparative analysis with the field humidity measurement. The results show that the maximum humidity area of the fully mechanized mining face is located near the coal cutter( the humidity value is close to 98%),there is a high humidity area with ribbon at the back of the coal cutter close to the coal wall,and the humidity value of outlet position is higher than that of inlet position,that the overall deviation of the simulated humidity value from the measured humidity value is within 1. 8%,and that the numerical simulation method is accurate and reliable,which can be used to study the humidity field in the underground fully-mechanized mining face.
