平顶山煤田地温分布规律及其影响因素分析

Analysis on Temperature Distribution and Influencing Factors in Pingdingshan Coal Field

平顶山煤田存在高温异常现象,严重影响煤矿的安全高效开采。根据平顶山煤田各个矿井的地温资料数据,分析平顶山煤田地温场的分布特征及影响因素。分析表明,平顶山煤田各矿井地温梯度普遍偏高,高温异常区具有断裂和裂隙密集发育、褶皱隆起的特点,地温分布受区域地质构造、地下水活动、岩石性质和盖层性质等因素的影响。

Pingdingshan coalfield has a phenomenon of geothermal anomaly,seriously affect the safety and efficient exploitation of coal mine.Based on the temperature data of each mine in Pingdingshan coalfield,analyze the distribution of Pingdingshan coal geotemperature field and influencing factors.Research shows that each coal mine in Pingdingshan coalfiled has this characteristics：geothermal gradient is generally on the high side,high-temperature anomaly area have faults and fissures intensive development,fold is up lifted,abnormal high temperature is under the regional geological structure、the activities of the groundwater、rock properties、cap rock properties and so on.
