深井开采地温场监测技术及分布规律研究

Study on monitoring technique and distribution regularity of geothermal field in deep mining

在深井开采过程中,地热是导致井下热害的主要原因。热量源源不断地从巷道围岩传递到井下工作面,使工作面气候环境恶化,危害矿山生产安全。本次研究采用合理的地温监测技术,研究深井矿山围岩地温场分布规律,为矿山进行热源分析、地温预测、通风降温等技术研究提供了重要依据。

In deep mining,geothermal energy is the main cause of underground heat disaster.The heat continuously transfers from wall rocks around the tunnel to underground working face,worsening the underground working environment and endangering the safety of mine production.In this study,a reasonable ground temperature monitoring technology is adopted to study the distribution regularity of wall rock temperature fields in deep mine,which provides an important basis for conducting heat source analysis,temperature prediction and the study of ventilation cooling technologies.
