以新密市为中心的附近市县,分布着十分广范的石灰岩,由于亿万年的溶蚀、裂隙、溶洞发育,造成了大面积的贫水区。为了农田灌溉和人畜吃水,在石灰岩地区打了许多机井,其中部分出水量小。我们经过了多年实践,创造一套碳酸盐岩井综合洗井新技术。石灰岩的主要化学成分是碳酸盐,这种岩石在地下水的作用下,易于溶解而形成裂隙、溶洞。在石灰岩地区找水是相当困难的,一是渗透于基岩的地下水顺裂隙、溶洞而流走,有些地方根本找不到水;
In the nearby cities and counties around Xinmi City, a very wide range of limestone is distributed. Due to millions of years of erosion, fissures and karst caves, large-scale water-poor areas are created. In order to irrigate farmland and draft, a number of wells were drilled in the limestone area, some of which had small amounts of water. After years of practice, we have created a set of new integrated well washing technologies for carbonate wells. The main chemical composition of limestone is carbonate, the rock in the groundwater, easy to dissolve and the formation of cracks, caves. It is quite difficult to find water in the limestone area. First, groundwater infiltrated into the bedrock flows through the fissures and karst caves, and in some places water can not be found at all.
