淮南潘三矿区地温分布规律及其影响因素分析

潘三矿位于淮南煤田潘谢矿区东区,潘集背斜西段南翼。根据对矿区内15个测温钻孔的研究,发现该矿存在着明显的地温异常。在纵向上,表现为地温温度随深度的增加而增加,并呈现良好的线性趋势,具有传导型增温特点;在横向上,受构造控制作用和上覆松散层厚度影响,靠近背斜轴部和松散层较厚的地方,地温梯度相对较高;岩浆岩的侵入和地下热水的运移也对地温有一定的影响。总体上,研究区地温受构造控制作用明显。该研究对矿区的热害预防提供了基础技术参数。

Geotherm Distribution Pattern and Impacting Factor Analysis in Panji No.3 Coalmine,Huainan

The Panji No.3 coalmine is situated in eastern part of the Panji-Xieqiao mining area, western sector of Panji anticline south limb. According to temperature measured data from 15 boreholes in the mine area, have found obvious geotherm anomaly existed. Verti-cally, geotemperature is increasing along with depth and presents good linear trend with conductive temperature increasing characteris-tic;horizontally, controlled by structure and overlying loose bed thickness, near the anticline axis and thicker loose bed, geothermal gra-dient is relatively high;magmatic rock intrusion and underground hot water migration also have certain impact on geotemperature. As a whole, geotherm is obviously controlled by structure in the area. The study has provided basic technical parameters for thermal damage prevention in the mine area.
