淮北矿区地温变化规律及其异常因素分析

Analysis on the Regularity of Ground Temperature Change and Its Abnormal Factors in Huaibei Mining Area

地温就是地热,即地球内部储存着的巨大的热能,矿井地温场是煤矿生产安全过程中一个重要的指标,也是学者们关注的焦点。在深井开采过程中,地热是导致井下热害的主要原因。随着我国煤炭工业的发展,矿井深度不断增加,热量源源不断的从向导围岩传递到井下工作面,使工作面气候环境恶化,危害矿山生态安全。本文通过对地层、构造、岩浆、地下水的分析,基于地质热学和热力学理论,系统地较全面地阐述了淮北矿山地温场的分布规律及引起地温异常的影响因素,为淮北矿区矿井热害控制提供基础技术参数。

Geothermal is geothermal energy, the heat energy that is stored in the interior of the earth’s huge, mine geothermal field is an important index in the process of safety production in coal mine, is also the focus of scholars. In the process of deep well drilling, geothermal is the main cause of the underground heat harm. With the development of coal industry in our country, the depth of the mine increases, heat flowing from the wizard of surrounding rock to the underground coal face, the face climate environment deterioration, harm to ecological safety in mines. In this paper, through the analysis of the stratigraphic, tectonic, magmatic and groundwater, based on the geological thermal and thermodynamics theory, this paper systematically and comprehensively expounds the distribution law of geothermal field and the influencing factors of geothermal anomaly in Huaibei mine, which provides basic technical parameters for the control of mine heat damage in Huaibei mine.
