砚山县平远干旱盆地地质构造赋水性探论

A DISCUSSION ABOUT THE WATER ABUNDANCE OF GEOLOGICAL STRUCTURE IN THE PINGYUAN DRY BASIN,YANSHAN COUNTY

平远盆地属地质构造和水文地质条件特别复杂的高原裸露型岩溶盆地,洞穴资源十分丰富,但找水十分困难。盆地大水量的水文井与地质构造有关,特别是与断裂构造关系密切。富水块段都处在特殊地质构造位置和水文地质单元上,这些规律性对探索平远盆地找水方向和选择供水井位置大有益处。

The P ological structure and ingyuan basin belongs to the plateau bare karst basin with very complicated gehydrogeological condition, which has very abundant cave resources. However, it is very difficult of searching for water. According to the practice in many years, we discover that all hydrogeological wells with great water yield in Pingyuan dry basin are related to the geological structure, especially the fault structure. All blocks rich in water are in the special geological structural position and hydrogeological unit. these regularities are very helpful in the searching for the water-prospecting direction and selection of the position of water supply well.
