金川二矿井下热力状况研究
|
摘要
本课题是针对我国矿井已进入深部开采,受高温热害严重威胁的现状而提出的。论文分风流热力分析与井下风流温度预测两大部分。首先从矿井热力参数观测与分析入手,对温度、压力、风速、密度、含湿量、相对湿度、焓等的物理意义进行了说明,指出它们之间的相互关系,由观测数据得出风流自地面至回采工作面热力变化规律及热湿源分布。详细分析了矿井的热湿源,即地表大气状态、空气自压缩、围岩散热、矿井水散热、机电设备放热、运输中煤炭和矸石放热、氧化放热和以及人员放热等,得出各热源散热量的计算模型。整理得出了井下各段风流预测的数学模型,针对金川二矿850m中段选取有代表性的两个地点进行风流温度预测,即18行副井井底车场和掘进工作面。预测结果表明:18行副井井底车场的风流温度为23.4℃;掘进工作面迎头风流温度可达35.1℃。预计在最热月采掘面的风流温度将会更高,因此必须对深部开采的热害问题引起重视。文章还搜集整理了一些常用的矿井降温方法,并针对金川二矿实际情况,提出了几点矿井降温的建议,包括选择用多级机站通风、矿工个体防护等。
This topic is aimed at the mines in China has entered a deep shaft mining, which bring a serious threat subject to high temperature thermal damage. Paper is divided into two major: Underground thermal analysis and air temperature prediction in mine. First, from the observation and analysis of thermal parameters of mine, make a describe to the physical meaning of temperature, pressure, wind speed, density, moisture content, relative humidity, enthalpy,etc,and pointed out the inter-relationship between them. Then obtains the thermal variation lows from the ground to the mining face by these observation data. Make a detailed analysis to the mine heat and moisture source, they are the atmosphere state on surface, air compression, the rock heat, mine water cooling, electrical and mechanical equipment heat, coal and gangue heat in transportation, oxidation exothermic heat and personnel, etc, Come to the calculation model for the amount of heat sources. Finishing obtained mathematical model of airflow prediction Underground sections, and then proceed temperature forecast aimed at the selected two representative sites in the middle 850m in Jinchuan Mine 2,they are bottom yard of auxiliary shaft in line 18 and heading face. The prediction results show that temperature of bottom yard of auxiliary shaft in line 18 is 23.4℃; the head-on airflow temperature in Heading face can reach to 35.1℃. Expected to be the hottest month extractive surface temperature will be higher, so it is necessary to cause attention for heat injury in deep mining. The article has also collected a number of cooling method of mine which commonly used, to the actual conditions in Jinchuan 2, the author put forward some recommendations of mine cooling, including the selection with multi-level machine station.
