地温异常是影响矿井建设及煤矿安全生产的重要因素,钻孔测温是获取地温资料的常用和主要手段。由于测温钻孔的工程量大,在某一区域通常难以达到足够的覆盖密度。以丁集矿地温研究为例,探讨了用ANSYS软件数值模拟进行地温模拟研究的问题。该方法充分考虑了所研究区域的地层热导率等热物特性及地质构造,通过对比实测的钻孔数据,实测数据与模拟结果的趋势和规律相一致。用ANSYS数值模拟地温可以为后续矿井地温异常区范围圈定、热害防治措施制定和矿井生产能力提高提供分析依据。
The geothermal anomaly is an important factor that affects mine construction and coal mine safety production. Drilling temperature measurement is a common and primary means of obtaining geothermal data. Due to the large amount of temperature drilling, it is usually difficult to achieve sufficient coverage density in a certain area. Taking the study of the geothermal temperature in Dingji Mine as an example, the issue of simulating the geothermal field by numerical simulation using ANSYS software is discussed. The method takes full consideration of the thermal properties and geologic structure of the thermal conductivity and other geological formations in the studied area. By comparing the measured borehole data, the measured data are consistent with the trends and laws of the simulated results. Numerical simulation of ground temperature with ANSYS can provide the basis for follow-up mine geothermal anomaly zone delineation, thermal harm prevention and control measures and improve mine production capacity.
