井矿盐类矿石水溶性能系列试验要点探究

Research on the Key Points of Series Test on Water Solubility Energy of Well and Rock Salt Ores

井矿盐类矿石埋藏于地下深处,根据盐类矿石易溶于水的特性,开采一般采用水溶采矿法。水溶性能试验室系列试验是在试验室以岩心样品模拟现场的实际开采,得出开采时所需要的相关参数。本文从试验角度,分析了侧溶、上溶、卤水膨胀率、水不溶残渣的颗粒度分析等水溶性能试验室系列试验的要点和影响因素,为水溶开采的设计提供了依据。

Well and rock salt ores are buried deep underground.According to the characteristics of salt ores being easily soluble in water,water-soluble mining method is generally adopted for mining.The series of water-soluble energy test in laboratory is to simulate the actual mining in the field with core samples in the laboratory to obtain the relevant parameters,the key points and influencing factors of a series of laboratory tests on water solubility,such as swelling rate of side-dissolved brine,granularity analysis of water-insoluble residue,etc.,are analyzed from the experimental point of view,.it provides a basis for the design of water dissolution mining.
