摘　　要：宁晋石盐田是河北省境内发现的一处大型石盐田。根据宁晋石盐田纪昌庄盐矿4口探采结合井采取的水溶性能试验数据,探讨了本区石盐矿层的溶解特性。结果表明本区石盐矿层水溶法开采条件优越,且在开采初期,应尽量降低向井内循环注入的淡卤水浓度,以加快溶腔的形成速度;正常生产阶段,通过调整卤水浓度,控制溶腔形状,在保证卤井产能的前提下,尽量排出井内残渣,使地下石盐资源得到更充分的开发利用。Ningjin Shiyantian is a large salt mine found in the territory of Hebei Province. According to the water solubility test taken from four exploration and mining combined wells in Ning Jin Shi Yantian Jichang Zhuang mine , this paper solubility of halite deposits in this area. The results show that the halite bed water solution mining condition is superior initial stage of nroduction, it is necessarv to reduce concentration that iniected into the well to improve the rate ofdissolution cavity. In the normal production phase, by adjusting the concentration of brine and controlling the shape of dissolving cavity, we should try to exhaust residue in the well and guarantee halite resources underground is more fully exploited under the premise of ensuring the capacity of brine well.
