重庆南温泉背斜南温泉、小泉及桥口坝地下热水开发点为一个地下热水系统,过去由于缺乏对地下热水的可持续开发研究,各开发点盲目开采,使得有名的天然南温泉、小泉枯竭。目前开发商正在桥口坝开发地下热水,为了避免重蹈覆辙,及合理开发和保护地下热水资源环境可持续发展,必须进行地下热水可持续开发研究。在分析南温泉背斜地下热水系统物理模型的基础之上,建立相应的有限元模型,并采用实测水位与模拟水位对比进行模型校正,当模拟水位与实测水位相近时,所得的模型是符合客观实际的。采用此模型模拟不同可持续开发方案下,桥口坝地下热水的最大开采量,并对不同开发方案进行分析优选,得到最佳的可持续开发方案。 相似文献

地下矿山开采过程中要开掘大量的巷道与峒室,用以完成人员的进出与通风以及被开采下来的有用矿物的运输与提升工作.随着开采过程的进行,有些巷道与峒室将被破坏,而另外一部分则随着矿井或开采水平的报废而遗留在地层深处,成为永久性的废弃地下空间.矿山废弃地下空间实际上包含废弃的地下矿井所遗留的巷道、峒室等地下空间和生产矿井废弃采区或开采水平里的巷道与峒室两部分.这些废弃地下空间的存在不仅对未来相邻区域地下空间的开发与有用矿物的开采造成涌水、突气等巨大的安全隐患,而且还会引发地面沉陷等一系列环境问题.在解决地下水污染等问题的基础上,利用矿山废弃地下空间进行危险固体废物的无害化处理,将同时解决处置危险固体废物与处理矿山废弃地下空间危害的双重难题. 相似文献

漳州地下热水资源评价方法浅析 总被引:1,自引:0,他引:1
原《漳州地热详查报告》以开采模数法计算基岩裂隙热水允许开采量7598.2m3/d作为C级储量,《漳州盆地地下热水动态监测报告》以开采模数法加中温区试验推断法计算水温≥40℃基岩裂隙热水允许开采量5153.3m3/d,此二数值与实际开采量加基坑降水量之和对比分析,均偏小,以大井法计算水温≥50℃的孔隙热水允许开采量作为C级储量更为可靠,按水位降深5.45m计,并经垂向、侧向补给量保证验算修正后,允许开采量10208.97m3/d。 相似文献

深层地热能利用的困境呼唤地源热泵发展,地热水按不同地热异常带呈地热梯度,随着地下深度愈深,地热水温度愈高。为了满足使用对水温要求,人们常力求开采较深层地热水。上世纪70年代,地下几十米乃至百米多的浅层地热水大量采用并随意排放,造成地下水位下降,地面下沉。第三系地热水开采被限,并只准开采基岩下地热水。[第一段] 相似文献

The article describes the economy of exploiting heat from low-temperature geothermal sources for high-temperature heating of buildings using a heat pump. For the exploitation of low-temperature geothermal sources, a two stage heat pump with a heat exchanger was planned. The pump consists of two single stage heat pumps which use different refrigerants at each stage. At stage 1, the calculation of the heat pump is conducted with refrigerant R407c; at stage 2 of the heat pump, the refrigerant R600a is used. The main operational characteristics of a two stage heat pump are presented in the form of diagrams. For the exploitation of heat from geothermal water with a temperature of 45 °C, a profitability evaluation of the investment in the heat pump was carried out, using the method of the net present value. In the research, also the coefficient of profitability and the period of time in which the investment is going to return itself were established. 相似文献

The Praille–Acacias–Vernets suburb, located in Geneva, Switzerland, is today considered as an outworn city area (2.3 km2). It consists of parking lots, industries, businesses and marshalling yards. The Geneva Government decided to remodel this suburb to effectively allow for city growth while complying with the highest energy efficient and environmental standards in urban development. A masterplan was accepted in spring 2007. It did not take into account the various energy and natural resources of the area at that stage.BG Consulting Engineers was thus mandated to assess a set of resources related to energy and environment, such as geothermal power or roundwater. For this purpose, a new investigation method was tested. It integrated the Deep City approach (Swiss Federal Institute of Technology, Lausanne), which promotes the sustainable use of urban underground resources.The BG method consisted in (1) establishing a geodatabase regrouping all available data (Geographic Information System), (2) identifying, localising and quantifying the different resources and (3) identifying and discussing all synergies and conflicts that might arise during their exploitation. This third step constitutes a real improvement allowing for anticipated decision making, thus avoiding future compatibility issues.Results of this study consisted in lists and maps of (1) raw resources, (2) technical and economical opportunities and constraints of exploitation, and (3) practical synergies and conflicts of exploitation. In addition, further necessary studies were identified along with synthetic scopes of work.Results were convincing and highly considered by the Geneva Government. For example, geothermal power resources were localised along with possible exploitation technologies and quantified extractable power. Synergies like combined exploitation of geothermal power and groundwater were also identified while conflicts such as spatial occupation were localised and discussed. These examples, among many others, validate this BG innovative method integrating the Deep City concept. 相似文献
