胶东半岛矿山地热资源利用方法

随着矿产资源的大量消耗，矿山向纵深开采成为必然趋势，随之而来的地热问题也越来越多地显现出来；矿山地热水既是淡水资源又蕴含热能，极具利用价值。矿山地热虽是绿色能源，如不能合理转化利用，会造成井下高温，严重影响生产效率。以矿山地热资源循环利用为研究目的，从地温效应调控入风流温度、热泵技术在金属矿山中的应用以及地下水回灌系统的角度，分析了矿山地热的利用原理及方法，建立了浅层井筒与风流热交换模型、压力回灌三维非稳定流数学模型等相关理论模型，并对地热利用方法进行试验研究和分析，研究结果应用于胶东半岛典型金属矿山中。结果表明，对矿山地热资源的合理利用在理论上和实际操作上具有可行性，可为我国矿业绿色能源开发探索一条可能的途径。

Utilization Methods of Geothermal Resources in Jiaodong Peninsula Mines

With the large consumption of mineral resources，the deep mining in the mine becomes an inevitable trend，and more and more geothermal issues are emerging with it.The mine geothermal water is fresh water resource and contains heat energy，so it is very useful.Mine geothermal water belongs to green energy.However，without reasonably utilization，it will result in underground high temperature and seriously influence the production efficiency.In order to recycle mine geothermal resources，the principle and method of utilizing geothermal resources were analyzed from aspects of regulating inlet air temperature by the ground temperature effect，applying heat pump to metal mine and the recharging system of geothermal water respectively.Then，the corresponding theoretical models were built such as the heat exchange model between shallow borehole and air，the three-dimensional unsteady-flow mathematical model of pressure recharging.Experimental research and analysis on the utilization of geothermal resources were made，and then were applied into the typical metal mines in Jiaodong peninsula.The results showed that it is feasible for rationally utilizing mine geothermal resources in theory and practice.The research explores a possible way for development of mine green energy in China.
