摘要
针对我国华北煤田构造地质、水文地质、地温地质特征及地温资料来源、地温研究现状,提出了先建立煤井田地温场的数学物理模型并求出其数值解,再用其结果预测井田未知区地温分布的新方案。使地温预测工作程序得以简化、预测结果更为可靠。文中详细叙述了模型建立和边界条件选定方案,并以导水断层上盘为例,展示了数值模拟的效果。
Acording to the characters of the stractural geology, hydrogeology and geothermal geology in the coal—field in the northern of china, a method is proposed for predicting the rock temperature distribution in the coal mine field. That is the digital simulation method of the rock temperature field, which makes the result of the prediction more reliable, and simplifies the program of prediction. It is discussed in detail how to select the model and its boundary condition. Some examples on the hanging—wall block of the water-bearing fault are given to show the effect of digital simulation of the rock temperature(3 fig.).
