以实现矿山井下热害治理和热能源利用一体化为出发点,阐述利用流体渗流特性开发矿山地下热能的可行性;提出用高压水泵人工制造裂隙,用冷水冲刷地下热岩获取热能的想法;找出矿山井下自然涌水的主要原因;分析岩体裂隙变形的成因、特性,用数据表明建立岩体裂隙变形和渗流关系模型可以在等效连续介质状态下进行;最后建立了岩体裂隙变形与渗流关系模型,得出矿山地下水在岩体中的流动与岩体裂隙变形之间的关系。

In order to realize the integration of underground heat damage treatment and heat energy utilization,the feasibility of taking use of fluid seepage characteristics to utilize underground heat energy is explained,the proposal for using high-pressure pump artificial fracture,with cold water to wash underground hot rocks obtain heat energy is put forward,and the main reasons of natural groundwater bursting are found out.Through analyzing the causes and characteristics of rock mass fracture and deformation,the data indicated that it can be carried out under the state of equivalent continuous medium to establish the relationship model between rock mass fracture deformation and water seepage.Finally relationship model of rock mass fracture deformation and seepage was established to obtain the relationship of groundwater flow and rock mass fracture and deformation.
