由于基岩裂隙水埋藏、分布的复杂性和不均匀性,常使近在咫尺的相邻水井,涌水量可相差数十倍到上百倍;甚至在同一井位上,可能因井深和井型选择不当而不能成井。为了更加有效的开发利用基岩裂隙水资源,有必要对我国近年来丰富的布井经验加以总结。本文将着重论述在裂隙水及岩溶裂隙水分布区布置水井时,井位、井深、水位和井型确定的一般原理。
As the bedrock fissure water burial, the complexity of the distribution and inhomogeneity, often close to the adjacent wells, the water can be a difference of several times to hundreds of times; even in the same well location, may be due to well depth and well type Improper choice can not be made. In order to develop and utilize the bedrock fissure water resources more effectively, it is necessary to sum up the abundant well drilling experience in our country in recent years. This article will focus on the general principles of well location, well depth, water level and well pattern determination when laying wells in fissure and karst water distributions.
