在岩溶矿床的开发中,为防治地下水的危害,建造堵水帷幕是一种有效的方法。目前在建造堵水帷幕的课题中,往往偏重于注浆材料及注浆工艺的探讨,对水文地质条件在堵水帷幕建造方面的重要性,尚未得到应有的认识。实践证明,某些矿区因对水文地质条件重视不够,致使建成的帷幕得不到预期效果,因此,对水文地质条件掌握与研究的程度如何,常是能否建好帷幕的关键。 一、水文地质条件对建造堵水帷幕的影响 对建造堵水帷幕起影响的水文地质条主要有如下三个方面。s In the development of karst deposits, in order to prevent the harm of groundwater, building water blocking curtain is an effective method. At present, the construction of water curtains in the subject, tend to focus on the grouting material and grouting process of discussion, the hydrogeological conditions in the construction of water curtains, the importance of not yet get the due recognition. Practice has proved that some mining areas due to lack of attention to the hydrogeological conditions, resulting in the curtain did not get the desired results, therefore, to grasp the extent of hydrogeological conditions and research, is often the key to the curtain. First, the impact of hydrogeological conditions on the construction of water curtain The construction of water curtain closure of the hydrogeological strip mainly in the following three aspects. s
