| 摘 要： | 基于新郑矿区以平均每年0.0813×108m3的涌水量向地表排放热水,造成的地热资源损失和污染环境的现实,在分析地温地质条件基础上,利用热储资源量公式、卡明斯基公式和弹性储存量公式,分别计算了矿山开采前和开采后不同类型地热资源量,并对当前矿区地热潜能进行了评估。在此基础上,提出了选择煤层底板加固技术,保持岩溶裂隙水一定的水位、减少地下水排放和利用识别模型,选择适宜区段作为地热资源开采区,以调减矿山日常的排水量,尽可能维持渗流场基本不变,进而提高热储的潜能,实现节能减排,达到保护与利用地热资源的效果的建议。

| Abstract: | In consideration of ground surface geothermal water discharge of 0.0813×10^8m^3outflow mean annually from the Xinzheng mining area have caused geothermal resources loss and environment pollution. On the basis of geothermal geological condition analysis,using formulae of geothermal reservoir resource, Kamenski and elastic storage have estimated geothermal resources of different types before and after mining respectively, and evaluated current mining area geothermal resource potential. On this basis, suggestions of coal floor consolidating technology selection, karst fissure water stated water level retaining, groundwater discharge cutting down put forward. Using model of cognition selected appropriate sectors as geothermal resource exploitation area to reduce mine routine water discharge. To maintain seepage field essentially invariant as far as possible, and then enhance geothermal reservoir potential, realize energy-saving and discharge-reduction, thus amount to the purpose of geothermal resources protection and utilization. |
